When an optional XM Connect & Play module is connected and activated, and when there is sufficient signal strength for the XM system to operate, this button has a different set of functions than when traditional AM or FM radio is in use. See page 41 for more information on XM Radio operation. 9 Front-Panel Door: To open the door so that the front-panel jacks and controls behind this door may be accessed, gently pull the door down and toward you, using either upper corner of the door. ) Volume Control: Turn this knob clockwise to increase the volume, counterclockwise to decrease the volume. If the AVR 645 is muted, adjusting the volume control will automatically release the unit from the silenced condition. ! Input Indicators: One of these indicators will light to identify the currently selected input. Note that the entire list will light briefly each time the unit is turned on, as a test. @ Speaker/Channel Input Indicators: These indicators are multipurpose, indicating both the speaker type selected for each channel and the incoming datasignal configuration. The left, center, right, right surround and left surround speaker indicators are composed of three boxes, while the subwoofer is indicated by one box. The center box lights when a small speaker is selected, and the two outer boxes light when large speakers are selected. When none of the boxes are lit for the center, surround or subwoofer channels, no speaker has been assigned that position. The letters inside each box display the active input channels. For standard analog inputs, only the L and R will light, indicating a stereo input. For a digital source, the indicators will light to display the channels being received at the digital input. When the letters flash, the digital input has been interrupted. (See page 40 for more information on the Channel Indicators.) # Upper Display Line: Depending on the units status, a variety of messages will appear here. In normal operation, this line will show the current input source and identify whether an analog or digital input is in use. When the tuner is selected as the input, this line will identify the station as AM or FM and show the frequency and preset number, if any. When an XM Connect & Play module is connected and activated, and when there is sufficient signal strength for the XM system to operate, the XM channel number and signal strength will appear here. $ Lower Display Line: Depending on the units status, a variety of messages will appear here. In normal operation, the current surround mode will appear on this line. When an XM-Ready module is connected and activated, and when there is sufficient signal strength for the XM system to operate, a variety of messages and information, including the XM channel title name, the current artist and track title, the XM Radio channel category and, when available, local traffic and weather information, will appear here. % Surround Mode Indicators: One of these indicators will light to show the surround mode in use. Depending on the specific combination of input sources and surround mode selected, more than one indicator may light. (See page 38 for more information.) ^ Remote Sensor Window: The sensor behind this window receives infrared signals from the remote control. Aim the remote control at this area, and do not block or cover it unless an external remote sensor is installed.

System and Power Connections
The AVR 645 is designed for flexible use with multiroom systems, external control components and power amplifiers. Main Room Remote Control Extension If the receiver is placed behind a solid or smokedglass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, an optional remote sensor may be used. Connect the output of the remote sensor to the IR Input. If other components are also prevented from receiving remote commands, only one sensor is needed. Simply use this units sensor or a remote eye by running a connection from the IR Output to the Remote IR Input jack on Harman Kardon or other compatible equipment. If other Harman Kardon-compatible source equipment is part of the main room installation, the IR Output Jack on the rear panel should be connected to the IR IN jack on source equipment. This will enable the remote room location to control source equipment functions. When a remote IR sensor is used to control nonHarman Kardon source equipment, we recommend that you make a hard-wire connection or use an optional, external IR blaster connected to the Full Carrier IR Output B. If you are in doubt as to which IR Output jack to use for the equipment in your system, contact your dealer or installer, or the manufacturers support site and ask whether the unit to be controlled uses full carrier IR commands. When full carrier commands are used, make the connection to the Full Carrier IR Output. Otherwise, make the connection to the IR Output. NOTE: All remotely controlled components must be linked together in a daisy chain. Connect the IR OUT jack of one unit to the IR IN of the next to establish this chain.

Multiroom Audio Connections The AVR 645 is equipped with multizone capabilities that allow it to send a separate audio source to the remote zone from the one selected for use in the main room. Depending on your systems requirements, three options are available for audio connection: Option 1: Use high-quality, shielded audio interconnect cable from the AVR 645s location to the remote room. In the remote room, connect the interconnect cable to a stereo power amplifier. The amplifier will be connected to the rooms speakers. At the AVR 645, plug the audio interconnect cables into the Multiroom Audio Outputs 8 on the AVR 645s rear panel. Option 2: Connect the Multiroom Audio Outputs 8 on the AVR 645 to the inputs of an optional stereo power amplifier. Run high-quality speaker wire from the amplifier to the speakers in the remote room. Option 3: Taking advantage of the AVR 645s built-in seven-channel amplifier, it is possible to use two of the amplifier channels to power speakers in the remote room. When using this option, you will not be able to use the full 7.1-channel capabilities of the AVR 645 in the main listening room, but you will be able to add another listening room without external power amplifiers. To use the internal amplifiers to power a remote zone, connect the speakers for the remote room location to the Surround Back/Multiroom Speaker Outputs. Before using the remote room, you will need to configure the amplifiers for surround operation by changing a setting in the MULTIROOM menu, following the instructions shown on page 46. NOTE: For all options, you may connect an optional IR sensor in the remote room to the AVR 645 via an appropriate cable. Connect the sensors cable to the Multiroom IR Input e on the AVR 645 and use the ZR 10 remote to control the room volume. You may install an optional volume control between the output of the amplifiers and the speakers in options 1 and 2. A-BUS Installation Connections The AVR 645 is among the few receivers available that offer built-in A-BUS/READY operation. When used with an optional A-BUS product, you have all the benefits of remote zone operation without the need for an external power amplifier. To use the AVR 645 with an approved A-BUS product, simply connect it to the AVR 645 using standard Category 5 wiring that is properly rated for the specific in-wall installation. Terminate the wiring at the receiver end to a standard RJ-45 connector in compliance with the instructions furnished with the A-BUS product. No further installation or adjustment is needed, as the A-BUS jack on the AVR 645 routes the signals to their

move to that line; otherwise, press it again to move to the DOLBY SURR SETUP line and skip to the instructions for that setting. The SURROUND CONFIG line is your gateway to a broad range of surround mode configurations. To continue, press the Set Button p to go to the main SURROUND CONFIG menu (Figure 7).

Figure 7

The LOGIC 7 GLOBAL line is the only item on this menu page that is menu-specific, and it allows you to select whether or not Logic 7 will be the default surround mode for any incoming audio signal. The default setting is OFF, which chooses the native mode. Press the / Navigation Buttons D so that ON appears, to activate the global Logic 7 setting for this input. The remaining five items in this menu are global settings that take you to a submenu listing the individual surround modes available within the selected mode group. To select a surround mode list, press the / Navigation Buttons D until the onscreen cursor is pointing to the desired mode, and then press the Set Button p. Within each menu, press the / Navigation Buttons D to move the cursor up and down through the list, and then press the / Navigation Buttons D to turn the mode ON or OFF. When a mode is ON, the mode will appear in all menu selections whenever you are changing the surround mode. When a mode is OFF, the mode will not appear. Some modes, such as Dolby Digital, DTS and the Stereo mode in the PCM menus, are not defeatable. A complete list of the AVR 645s surround modes is found on page 60, but here are some items that will help you decide which modes you want included in your setup, and which modes you may wish to turn off. The DOLBY MULT CONFIG group contains the surround modes available when a multichannel Dolby Digital, encoded source is present. This includes both the discrete Dolby Digital modes, which cannot be turned off, as well as other modes which may be applied as post-processing on the source and system speaker configuration.

Figure 6

The first line on the menu allows you to select the input for which the specific surround settings will be applied. Press the / Navigation Buttons D to select the input source to be configured. The AUDIO IN-PORT and AUDIO IN lines are for display only and may not be changed through the SURROUND SETUP menu. The AUDIO IN-PORT displays the physical connection source for the current active input, and the AUDIO IN line shows the signal type present. Note that an UNLOCK message in the AUDIO IN line indicates that a digital physical input source has been selected, but that no data stream is present. When the input selection has been made, press the / Navigation Buttons D to move to the next configuration line. The ADC SAMPLING line is where you determine whether the units upsampling feature is turned on or off. The default setting of 48kHz puts the feature in a bypass, or off, mode and will pass digital audio data through the DSP at its native sample rate. To process incoming 44.1kHz signals at a higher resolution, upsampled 96kHz sample rate, press the / Navigation Buttons D once so that 96kHz is highlighted.

At the NEAR FIELD MESSAGE menu, you will see an instruction to place the microphone in a different position than the one used for the initial Far Field measurements. This time, place the microphone close to the speaker to be measured, at a distance of about 2 feet. The top of the microphone should be pointed toward the speaker, rather than pointing up as was done for the Far Field tests. Press the Set Button p to continue. Step 9. You will now see a WARNING message similar to the one shown in Figure 11 except that it will contain an option to return to the NEAR FIELD EQ SELECT menu (Figure 15) as well as the ability to return to the MASTER MENU. If you
Step 12. If a NEAR FIELD ERROR message appears, as shown in Figure 17, make certain that the microphone is about 2 feet from the speaker being tested and that the top of the microphone unit is pointing toward the speaker. You may also have to raise or lower the master volume to achieve accurate readings. After checking these two items, as needed, make certain that the cursor is pointing to the BACK TO NEAR FIELD line and press the Set Button p. This will return you to the NEAR FIELD EQ SELECT menu (Figure 15) where you should repeat Steps 8 through 11, adjusting the mike placement and volume level as needed until the NEAR FIELD COMPLETE menu (Figure 16) appears after the test tone stops.

Speaker Size Menu Although most listeners will prefer to take advantage of the accuracy and speed of EzSet/EQ to make all of the necessary speaker adjustments, advanced users may wish to experiment with how different combinations of settings sound in their home theater environment or to use settings other than those calculated by EzSet/EQ, to accommodate personal listening preferences. The menu system used in your AVR 645 differs somewhat from conventional speaker setup menus in that it consolidates the speaker size and crossover into one convenient menu. Even if you are familiar with making these adjustments, it is strongly recommended that you read the following section of this manual. On the SPEAKER SIZE menu (Figure 19) you have the option to change the type of speaker configured for each of the four position groups, to change the crossover setting for any one of those speakers, to adjust the setting point for the low-pass filter that determines which frequencies are sent to the subwoofer for low-frequency effects (LFE) signals, to change the subwoofer bass redirection mode when the Front Left/Right speakers are set to Large and to change the setting for the subwoofer size. If, as recommended, you have first run the EzSet/EQ system, as shown on pages 2730, the settings established by EzSet/EQ will be displayed as a starting point for any manual adjustments. You may reestablish those settings at any time during an adjustment on this menu by pressing the / Navigation Button n until the cursor is on the EZSET SETTINGS line of the menu and then pressing the / Navigation Button n so that ON is highlighted in reverse video. Note, however, that once this is done, any manual adjustments made will be lost and must be reentered. Speaker Size At each of the four speaker group positions, you have the ability to select the speaker size and, when a Small speaker is selected, the frequency below which low-frequency information is sent to the subwoofer, as opposed to the speakers for the channel being adjusted. For that reason, before making the adjustments on the FRONT L/R, CENTER, SIDE SURR and BACK SURR menu lines, it is important to know the frequency range for the speaker. This information is typically found in the Specifications section of the speakers owners manual. If you cannot find the specification for the lowest frequency the speaker can handle, start with the settings entered by running EzSet/EQ and then try one setting above or below the existing entry. We do not recommend changing the crossover point more than

When there are no speakers available at a specific position, select NONE. When this option is chosen for the Center or Side Surround speakers, the sound that would normally be sent to these channels will be split between the front left and right speakers. Note that when your system does not include Center or Surround speakers, the use of Dolby Virtual Speaker as a surround mode may provide a sound field that simulates the presence of these speakers. (See the appendix for more information on the Dolby Virtual Speaker mode.) Note that when NONE is selected for the Back Surround speakers, the 6.1/7.1 channel surround modes are not available. When this is the case for your system, you may wish to take advantage of the availability of the unused amplifier channel pair to power a second set of speakers in another room. (See page 46 for more information on amplifier configuration.) Once any desired changes have been made to the speaker size and/or crossover, press the / Navigation Button n to move the cursor to any other line on this menu to make a setting change, or go to the BACK TO MANUAL SETUP menu and then press the Set Button p to continue with overall configuration. LFE Low-Pass-Filter Setting The LFE LP FLT line selects the frequency setting below which sounds that may be available from a special low-frequency effects (LFE) track are sent to the subwoofer. In most cases, this setting will be set accurately by EzSet/EQ but, should you wish to make a change from that setting or the 120Hz frequency that is most commonly used in the creation of LFE channels by motion picture sound mixers, after making sure that the SPEAKER SIZE menu (Figure 19) is on the screen, press the / Navigation Button n so that the cursor is pointing to LFE LP FLT. Press the / Navigation Button n to begin the selection process, and note that the warning message (Figure 20) will appear reminding you to rerun EzSet/EQ after all changes have been made. When the SPEAKER SIZE menu returns to the screen, press the / Navigation Button n to make your selection. When the desired setting appears, press the / Navigation Button n to move the cursor to any other line on this menu where you wish to make a setting change, or go to the BACK TO MANUAL SETUP menu and then press the Set Button p to continue with overall configuration. Sub Mode Setting When the Front Left/Right speakers are configured as Large and a subwoofer is detected by EzSet/EQ

Figure 19

To change the setting for any of the four speaker positions, press the / Navigation Button n until the cursor points to the line where you wish to make the change. Press the / Navigation Button n to change the setting, but note that when you do this for the first time in the menu, a warning message (Figure 20) will appear in the on-screen display reminding you to rerun EzSet/EQ after you are finished with any speaker configuration changes. This is necessary to make any level output adjustments needed after the setting changes so that the new configuration will be properly integrated.

Figure 22

To provide the maximum flexibility, channel output level adjustments may be made either with or without the internal test tone, and when the tone is in use it may be programmed to automatically circulate among the active channels or to only move from one channel to the next on your command. When the CHANNEL ADJUST menu first appears we recommend that you always run the test tone once the automatic mode to verify that the speakers have been properly connected. To do this, press the / Navigation Button n again until the cursor is on the TEST TONE line and then press the / Navigation Button n until AUTO is in highlighted video. This will cause the test tone to circulate among all of the channels for five seconds at each position. As the test tone circulates, the cursor will flash and move next to each position to indicate where the tone should be coming from. If the tone is coming from a different speaker than the one indicated on the menu screen turn the AVR 645 off using the Main Power Switch A and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is connected to the correct output terminal. When you have verified that all speakers are

Page 34

connected to the correct output terminal, turn the AVR 645 back on and return to this menu to resume the channel adjustment procedure. If any speaker connections were changed we also recommend that you rerun EzSet/EQ before making any manual calibration adjustments. After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left speaker as a reference, press the / Navigation Button n on the remote to bring all speakers to the same volume level. When the / Navigation Button n is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume after five seconds. Continue to adjust the individual channels until the volume level sounds the same from each speaker. Adjustments should be made with the / Navigation Button n on the remote control only, NOT the main volume controls. If you are using a soundpressure level (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow. When all channels have an equal volume level, the adjustment is complete. To exit this menu, press the / Navigation Button n until the cursor is next to the BACK TO MANUAL SETUP line, and then press the Set Button p to return to the MANUAL SETUP menu. In addition to having the test tone circulate automatically, you may also turn the test tone on, but advance it from one channel to the next manually. This allows you to make calibration adjustments, but to have more control over the way the test tone is moved among the channels. To change the tone manually, first make certain that the CHANNEL ADJUST menu is on the screen, following the instructions shown above, and then press the / Navigation Button n until the cursor is on the TEST TONE line. Next, press the / Navigation Button n until MANUAL appears. This will start the test tone from the front left speaker position but, rather than circulating to the next channel every five seconds as is the case in the automatic mode, you must press the / Navigation Button n to change the channel the test tone is being sent to. When you have circulated through all channels the test tone will stop, but you may restart it by returning to the TEST TONE line again and activating manual sequencing. The final option for tone adjustment using the menu system is to not use the internal test tone at all. To do this, simply use the / Navigation Button n to change the channel and then use the / Navigation Button n to change the output level. When making channel output adjustments without the internal test tone we strongly recommend that you use a test disc in the repeat mode on your DVD or CD player so that the signal being used is constant throughout the adjustment process. The output levels may also be adjusted at any time using the remote control and semi-OSD system. To adjust the output levels in this fashion, press the Test Button f. As soon as the button is pressed, the test tone will begin to circulate as indicated earlier. The correct channel from which the test noise should be heard will be shown in the lower third of the video screen and in the Lower Display Line $. While the test noise is circulating, the proper channel position will also be indicated in the Speaker/Channel Input Indicators @ by a blinking letter within the correct channel. To adjust the output level, press the / Navigation Button n until the desired level is shown in the display or on the screen. Once the buttons are released, the test noise will begin to circulate again in five seconds. When all channels have the same output level, press the Test Button f again to complete the process. NOTE: Output level adjustment with the test tone is not available in the Surround Off modes. In addition to the controls for selecting channels and the test tone operation, the settings on this menu also allow you to reset the level settings to either the factory default of 0dB or to reestablish the settings that were entered by running EzSet/EQ. To reset all channel levels to 0dB, press the / Navigation Button n so that the cursor is pointing to the LEVEL RESET line and then press the / Navigation Button n once so that ON appears in highlighted video. To return to the settings established by EzSet/EQ, even if you have made manual changes to the output trims using the steps shown above, press the / Navigation Button n so that the cursor is pointing to the EZSET SETTINGS line and then press the / Navigation Button n once so ON appears in highlighted video. Remember that after turning the EzSet/EQ settings back on you must return to this menu line and change the setting to OFF if you wish to make any manual trim adjustments. The final setting in this menu enables you to have the output levels remain the same for all inputs or to be adjusted differently for each (or any) input. While most listeners prefer to keep the same output levels for all sources, you may wish to raise or lower some channels, particularly the subwoofer output for a specific source such as a CD that is primarily used for music playback. To enter individual settings for a specific channel, first make sure that you have either run EzSet/EQ and/or made any desired manual trim adjustments to set a baseline for all channels. After that is done, press the OSD Button U to exit the menu system and then select the input for which you wish to enter different level settings by using either the Input Source Selector 7 on the front panel or the buttons on the remote that are used to select an input source deXh. Next, return to the CHANNEL ADJUST submenu using the steps outlined above. At the CHANNEL ADJUST menu, press Navigation Button n until the cursor is pointing to the LEVEL TRIM line and then press the / Navigation Button n once so that INDEPENDENT appears in highlighted video. When this setting is active you may change the channel output levels for any input without changing the settings previously established for another.

Figure 23

The letters inside the boxes tell you which channels are receiving an input signal. Since conventional analog audio is only two channels, the L and R letters will light with any analog source. When a digital source is in use, you will see letters displayed that correspond to the number of channels in the incoming data stream, which may be just the L and R for two-channel PCM or 2.0 Dolby Digital material. When a 5.1 signal is being received, the L/C/R/SL/SR indicators will light, with the LFE indication also being shown when an LFE signal is present. All seven indicators, including the SBL/SBR letters, will light for a 7.1 signal, and a horizontal line is shown to connect the SBL/SBR indicators when a 6.1 source is in use. It is important to note that although Dolby Digital, for example, is referred to as a 5.1 system, not all Dolby Digital DVDs or programs are encoded for 5.1. Thus, it is sometimes normal for a DVD with a Dolby Digital soundtrack to trigger only the L and R indicators. NOTE: Many DVD discs are recorded with both 5.1 and 2.0 versions of the same soundtrack. When playing a DVD, always be certain to check the type of material on the disc. Most discs show this information in the form of a listing or icon on the back of the disc jacket. When a disc does offer multiple soundtrack choices, you may have to make some adjustments to your DVD player (usually with the Audio Select button or in a menu screen on the disc) to send a full 5.1 feed to the AVR 645. It is also possible for the type of signal feed to change during the course of a DVDs

Bridge

The AVR 645 is equipped for use with Harman Kardons optional TheBridge iPod docking station. When The Bridge is connected to the AVR and an iPod properly docked, you may use either remote to control the iPod for audio playback while using the front-panel display and on-screen semi-OSD messages to help you locate tracks or view information about the track being played. In addition, connecting an iPod to the AVR 645 through The Bridge also charges the iPods battery. Using the DMP AUTO POWER menu option, as described on page 45, you may even have the AVR 645 automatically turn on with your iPod as a playback source whenever the iPod is turned on.

Changing Devices

In the factory default settings, the AVR remote is programmed so that the commands transmitted correspond to the device selected by pressing one of the Input Selectors 3. This is logical, as you want the remote to control the device you have selected. However, in some circumstances you may have configured your system so that the devices connected to the AVR 645 do not correspond to the default device settings and the legends printed on the remote. For example, if your system has two VCRs you may connect the second VCR to the VID 2 input. There is no problem in doing that, but in normal operation the commands issued after selecting the VID 2 input are for a television, not a VCR. The AVR remote allows you to correct that situation through the Changing Devices process. This enables you to assign the codes from one type of device to a different button. For example, in the steps below, we will explain how to program the VID 2 buttons to provide the commands to operate a VCR. Of course, you may program the remote to have any of the devices take on the code set of any other device, as your system requires. And, with the AVR remotes Rename function, you can even change the way the name of the device appears on the remotes LCD so that you see exactly which commands are being sent. To program the buttons normally assigned to one device for the commands of another, pleasefollow these steps: 1. Press and hold the Program Button O for about three seconds while the message shown in Figure 26 appears in the remotes LCD Information Display 2. Release the button when the red light under the Set Button F appears. 2. The remotes MAIN MENU message (Figure 27), will appear in the LCD and the Set Button F will remain illuminated in red. Press the Navigation Button D twice so that CHANGE DEVICE appears on the bottom line of the LCD screen, as shown in Figure 40. Press the Set Button F to begin the process of reassigning the commands used for a particular device.

MAIN MENU CHANGE DEVICE

Figure 47
4. Once the old device type has been selected, you need to tell the remote which set of remote codes to use as a replacement for the device just selected. When the instructions shown in Figure 48 appear, press the / Navigation Button D to scroll through the list of device categories to find the name of the device that you wish to use. The old device name will remain on the left side of the LCD screen, while the replacement device list will scroll to its right. For example, press the Navigation Button D until the display screen reads TV<-VCR to have the VID 2/TV Button transmit the commands used to control a VCR. Press the Set Button F when the desired device combination appears.

5. Once the new device is selected, the remainder of the process will select the codes for the specific brand to be used, and for that reason they are identical to the way a device is programmed using manual entry. Continue the process as outlined in the next few steps, remembering that if the codes for your specific device are not found, you may select any brand and then learn the proper codes into the AVR remote using the process outlined on page 49. To begin the process, start by selecting the brand of device, as shown in Fig. 30. Press the / Navigation Button D until the brand name of the device you are programming into the remote appears on the lower line of the display and then press the Set Button F. 6. The next step is important, as it determines which codes will operate the source device or display. Point the AVR remote at the device being programmed and, following the instructions shown on the remotes LCD Information Display 2, press and release the Numeric Keys c one at a time, starting with the 1 Button c. After you press the 1 Button c, the remotes LCD screen will briefly go blank as the code is

Macro Programming

Macros enable you to easily repeat frequently used combinations of multiple remote control commands with the touch of a single button. Once a macro is programmed, you may send up to 20 commands with one press of the Power On or Macro buttons. This will greatly simplify the process of turning on your system, changing devices or other common tasks. Thanks to the remotes two-line display, it is easier than ever for you to take advantage of the power of macro commands.

Recording a Macro To record a macro into the remotes memory, follow these steps: 1. Press and hold the Program Button y for about three seconds while the message shown in Figure 26 appears in the remotes LCD Information Display 2. Release the button when the red light under the Set Button F appears. 2. The remotes MAIN MENU message (Figure 27), will appear in the LCD and the Set Button F will remain illuminated in red. Press the Navigation Button D so that MACRO appears on the bottom line of the LCD, as shown in Figure 49. Press the Set Button F to enter the main macro menu branch.

in the order you wish them to be transmitted. Remember that when you want to change devices, you must first press the Input Selectors d for that button, and then press the Command or Function key. Since we want to program a series of events that occur each time the Power On button is pressed, press the AVR button. In your specific macro, this is the first command button.

4. Press the Set Button F one more time. The LCD will show the word SAVING on the top line for about 2 seconds and then flash SAVED four times on the bottom line to indicate that the setting has been accepted by the remotes memory. 5. The remotes backlighting will now turn on whenever a button is pressed. To revert to the original setting, follow the four steps shown above, but in Step 3, select the option that has the word NORMAL on the bottom line of the LCD. Additional Notes on Configuring and Operating the Remote When the remote is being programmed, it will automatically time-out if no button is pressed within a 30-second period. The message shown in Figure 91 will appear briefly, and the remote will then exit the feature being programmed and any data entered will be lost.

Backlight Options

The AVR 645s remote has a built-in backlight system that makes it easier to use the remote when the room lighting is dimmed for an optimal home theater experience. To turn the backlighting on, simply press the Light Button z. That button is made from a special glow material that makes it easier to find in dark rooms. This glow feature does not use any battery power, so the glow will fade when the remote is kept in a dark room for an extended period of time. You may recharge it by placing the remote in normal room lighting for a few hours. Once the Light Button z is pressed, the remotes backlighting will remain on for approximately 7 seconds, and when you press any button on the remote while the backlighting is on, the light will stay on for another 7 seconds. However, the remotes Couch function will conserve battery power by turning both the backlighting and the LCD off when any button is pressed for more than 30 seconds. You may also configure the remote so that the backlighting will come on, any time a button is pressed. To set this option, follow these steps:

3. When the DEVICE PRIORITY message appears in the remotes LCD (Figure 88), press the / Navigation Buttons D to select the option that best suits your needs.
The programming or configuration process may also be stopped at any time by pressing the Clear Button 9. The message shown in Figure 91 will appear, the data entered in the current process will be lost and the remote will return to normal operation. Any process that was underway when the button will be pressed must be restarted.
