SETTING UP THE S170i

GETTING STARTED Before you make the first connection to your S170i, you should have the arrangement of your listening room/home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital questions of loudspeaker placement and listening/viewing positions is beyond our scope here. Suffice it to say that these two questions will influence your systems ultimate performance every bit as powerfully as your selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you, and to recommend reference materials.
ENGLISH FRANAIS DEUTSCH ESPAOL ITALIANO PORTUGUS SVENSKA 12

DEALING WITH HUM AND NOISE The S170i requires a grounded (3-prong) AC outlet. Employing a 3-to-2 adapter to eliminate the ground prong will not compromise electrical safety, but it may increase susceptibility to hum and noise. Hum and noise sometimes prove a challenge in complex, multichannel audio systems. Note these considerations to help prevent hum and noise problems: Power all your systems audio component from AC outlets originating from the same circuit of your house wiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on the same circuit. It may be useful to power video displays (and computers!) from outlets on another circuit, especially if that circuit is supplied from the other leg of the house wiring. Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure. A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, lowresistance contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging, since the gold (or copper) contact-plating of typical cable connectors, even very highquality ones, is very thin and easily worn. Track down hum/noise problems one component at a time, working backwards from the power amplifier(s). That is: Connect the speakers to the power amplifier only, and check for hum. Then connect the preamplifier alone (with no other components connected to the preamp) to the power and check for hum. Then connect one source component (a CD player, for example) to the preamplifier, and check for hum. At each stage, if hum/noise appears, examine the audio cabling and AC-power routing of the new component. In some cases, moving the new components AC cord to a different outlet, or installing a ground-lift (3-to-2-prong adapter) on its power cord, will eliminate the hum.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
The S170i preamplifier employs a simple, self-explanatory system of on-screen display menus that will appear on the systems video monitor/TV, useful both during setup and in day-to-day operation. While the OSDs are always helpful, it is also perfectly possible to operate (or even set up) the S170i without them, because the same basic data is always shown, though sometimes in shortened format, on the preamps own front-panel readout. DISPLAYING THE MENUS Once a video monitor (TV) is connected to the Monitor Output of the S170i, pressing the left or right cursor keys of the HTR 2 remote will access the S170is OSD (On Screen Display) where all system setup parameters can be easily adjusted using the up and down and [ENTER] keys. If the OSD does not appear, check your Monitor Out connections, and/or the settings of the <Video format> and <OSD display> items of the <Display setup> menu (see below) using the S170is frontpanel readout. NAVIGATING THE OSD AND MAKING CHANGES Use the remotes [Cursor ] keys to move up or down among any OSD menus list of items; use the [Cursor ] keys to change the value (setting) of any item; use remotes [Enter] key to select an OSD menu item. Selecting <Exit> from the Menu Page saves any changes you have made and departs that menu for the next higher level (or, from the Main Menu, turns the OSD off).

CONFIGURING THE S170i

You may set up your S170is levels, modes, and options in any order; it is not necessary to follow the order employed here. However, it is advisable to begin by configuring the S170is on-screen display options, since certain of these will affect the options made available to other setup routines. DISPLAY SETUP From the S170i OSDs Main menu, select the <Display setup> item using the remotes [Cursor ], and [Enter] keys. Using the [Cursor ] keys, set: <TV system> to NTSC for North American use, or PAL. for European use. Using the same remote keys, set: FRANAIS DEUTSCH ESPAOL ITALIANO PORTUGUS SVENSKA 14 <Superimpose> to On or Off. When Off is selected, on-screen menus will appear against a blue background, obscuring the current video program (if any); when On is selected menus will appear in white text superimposed upon the current video program (if any). <Temporary disp.> to Full, Simple, or Off. This controls how much information the S170i will display, monetarily, in on-screen text whenever powering on, selecting or changing a source or listening mode, or changing types of input signals. In Full mode a complete screen of data including input-name, audio-signal input, type, format, and listening mode, and video-signal type and input; in Simple mode, only input-name will appear. In Off mode no temporary on-screen info will be displayed. <Video format> to Auto, SVideo, or Compos. (composite-video). This controls which S170i video outputs will be active when a video input is selected; in Auto mode, the output mode will be selected according to the format of the incoming signal, with S-Video taking precedence where a source is connected via both formats. Note that the S170i preamplifier passes video signals even when it is switched to Standby. This permits video sources such as TeleText or Web-TV devices to be used even when the balance of the system is off. <OSD output> to Both, SVideo, Compos. (composite-video), or Off. This controls which video outputs will carry the S170is on-screen displays and menus. When Both is selected OSDs will be present on both the S-Video and composite-video Monitor Outputs; selecting SVideo or Compos. confines on-screen displays to each output alone, and Off disables on-screen displays altogether. (In all cases, basic data remains readable via the S170is front-panel readout, so you can, for example, see what youre doing even with OSDs set to Off.) NOTE THAT: OSDs do not appear on the component-video output Enabling OSD for a video output causes the video source signals in that format to pass through the OSD circuitry. Critical videophiles may wish to disable the OSD on the SVideo output for the most critical viewing/recording functions. <Distance units> to Feet or Meters. This selects by which measurement units you will enter your speaker-setup dimensions on the S170is <Delay setup> menu page (see below). ENGLISH

AUDIO SETUP The <Audio setup> menu enables you to modify tone-control settings and other listening options. Modifications you make on this menu will remain in affect until changed again, or until a Preset containing different settings is recalled (see below). DOLBY/DTS SETUP From the <Audio Setup> menu, select the <Dolby/DTS setup> item using the remotes [Cursor ] keys, then press [Enter], this will show a sub menu with the following choices to adjust the music modes of the Dolby and DTS surround decoders: <PL II Panorama> select <Off> or <On> When selected <On> the Panorama setting wraps the sound of the Front Left and Right speakers around you for an exciting effect. <PL II Center Width> select <Min.> <1> <2> <3> <4> <5> <6> <Max.> Center Width allows you to gradually spread the Center channel sound into the Front Left and Right speakers. At the widest <Max.> setting all the Center speaker sound is mixed to the Left and Right speakers. This control may help achieve a more spacious sound, or a better blend of the front image. <PL II Dimension> select <0> <1> <2> <3> Dimension adjusts the front/back balance to taste. <Neo:6 Center Image> select <Min.> <1> <2> <3> <4> <Max.> Center Image allows you to gradually spread the Center channel sound into the Front Left and Right speakers. PRESET SETUP The S170i incorporates five Presets, memory locations in which you may store five different combinations of tone-control and relative center/surround/subwoofer channel levels to suit different requirements. For example: You might configure Preset 1 for movie-surround with tone controls set to zero and relative channel levels left at their calibrated points, but set Preset 2 for music-surround listening with slightly elevated surround- and subwoofer-channel levels, slightly reduced center-channel levels, and modified bass or treble. Presets may be configured in any way, for any purpose you see fit. CONFIGURING PRESETS From the <Audio setup> menu, use the remotes [Cursor ] and [Enter] keys to select the <Preset setup> item. Using the same keys, select the Preset to be configured on the <Preset> item; then invoke the bass and treble settings desired for that preset using the same keys. With the same keys again, set the relative levels of Center, Surround, and Subwoofer channels for that preset. NOTE THAT: If surround-back speaker(s) are configured as present in the <Speaker setup> OSD menu (below), their levels will be controlled along with the surround-channels levels. Once configured, a Preset remains unchanged until you edit it via the <Preset setup> OSD menu. A Preset applies regardless of what source is selected, or what listening mode is in operation Cycling the S170i through its Standby mode will cancel any previously selected Preset, reverting both tone and all level settings to those set on the HTR 2 remotes LEVELS or MODE/MULTI.S screens (below), or via the S170i preamps <Audio setup> (above) OSD menu. If you would like to be able to set all channel-levels and tone-control values to zero without cycling through Standby, set one Preset to all zeroes. Channel levels stored in presets (are added to the setup levels established on the S170i preamps <Levels setup> OSD menu. For example: if your <Level setup> establishes <Center> at -3 dB and you dial in a Preset center-channel level of +2 dB, the net overall effect will be a center-channel level of -1 dB. By contrast, tone-control settings override <Audio setup> tone levels entirely. RECALLING PRESETS To implement the preset at any time, sequentially press the HTR 2s [AV PRESET] key and the corresponding numeral key <1 - 5>. Cycling the S170i through Standby mode will release the preset. the number of the preset invoked will appear briefly on the OSD and the S170is front-panel display.

The SPL meter should be placed at the primary listening position, at approximately the height of the seated listeners head. A tripod is very useful, but with a little duct-tape almost anything-a pole lamp, music-stand, or ladder-backed chair, for example-can do as well. Just be sure that no large acoustically reflective surfaces obstruct or are near the microphone element. Orient the meter with its microphone (usually at one end) pointing straight up toward the ceiling (not forward toward the speakers) and make sure that its C weighting scale is selected. To calibrate your system to play at the same objective loudness as a high-quality commercial cinema, set the meter to display 75 dB SPL. (On Radio Shack meters this necessitates either setting the meter to its 80 dB range and taking your readings at the -5 point, or selecting the 70 dB range and reading at the +5 point. This 75 dB SPL point is the official cinema (and THX) reference level. However, we note that no law requires you to use this level, and in fact this reference seems too loud for some users for home cinema playback. Many people find that calibrating to 70 dB SPL instead turns out just about right. CONFIGURING LEVELS From the OSD Main menu, select the <Level setup> item using the remotes [Cursor ], and [Enter] keys. Activate the test-noise signal with the remotes [Test] key(next to the [Volume up] key); you will here a surf noise that cycles through your speakers, beginning with the left-front. (If you do not hear the testnoise, check your Audio Connections (above), and your <Speaker setup> OSD menu settings, (above.) On the left-most column of the OSD youll see an > pointing toward <Left> (if the is at some other line, use the remotes [Cursor ] keys to move it to <Left>.) Now use the remotes [Cursor ] keys to adjust the noise output from the Left (left-front) speaker; the test-noise will automatically move there and the level offset reading on the right will change by 0.5 dB increments. If you are using an SPL meter, adjust the Left output to produce a reading of 75 dB SPL C-weighted (or whatever other reference level you have chosen to adopt) If you are balancing levels by ear you will have to choose one speaker-usually the center-as a reference and adjust each of the others so that is sounds as loud as the reference. Using the remotes [Cursor ] and [Cursor ] keys, adjust each speaker in turn to produce the same SPL meter reading (or subjective loudness), within 1 dB or better; the S170is ability to calibrate outputs by 0.5 dB steps should facilitate this precision. NOTE THAT: All speakers must be in their final locations before level-setting. Your subwoofer (if any) should be set with its integral crossover defeated, or set to its highest-possible frequency. Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always calibrate to exactly the same level offset readings. If you are particularly meticulous, you may wish to come back and re-check your level setup after completing the Delay setup routine (below). DELAY SETUP Your systems channel-delay settings are a subtle but important refinement of your setup. By informing the S170i of the loudspeaker-to-listener dimensions of each speaker, it will automatically impose the correct delays for each channel, optimizing imaging, intelligibility, and surround-sound ambience. Enter your dimensions with precision within about 1 foot/30 cm. CONFIGURING DELAYS From the OSD Main menu, select the <Delay setup> item using the remotes [Cursor ], and [Enter] keys. Using the [Cursor ] keys, set <Right> to the distance between your principal listening position and the front surface of the front-right loudspeaker. Using the same remote keys, set the remaining speakers, each to the distances of your system layout. Where a particular speaker is not present in your system, None will be displayed and no distance setting will be possible.

TRIGGER SETUP The S170i is equipped with 3 12-volt trigger outputs that may be used to turn on, activate, or otherwise control ancillary components or systems, such as power amplifiers, projector-lifts, lighting systems, and more. Their function could be as simple as powering up and down your NAD S250 power amplifier, or as complex as readying an entire home-theater room for use. For more technical information on the S170is 12-volt trigger outputs, see Appendix 1, or consult your installing NAD audio specialist. Simple 12-Volt Trigger Configuration Example: Powering the NAD S250 Power Amplifier The following example employs the S170is 12V Trigger #1 to turn the S250 amplifier on and off in concert with the preamplifier. Using the 12V Trigger cable supplied with the S170i connect the S170is rear panel 12V Triggers jack marked #1 to the 12V Trigger input jack on the power amplifier. Note that this custom cable provides an 1/8th-inch mini-plug on one end for the S170i, and a special, DC-style plug on the other to fit the S250 amplifiers trigger input. From the OSD Main menu, select the <Trigger setup> item using the remotes [Cursor ], and [Enter] keys. The <Trigger 1> listings should appear as follows (these are the defaults): polarity Posit. delay No duration Infin. If any other settings are in place, use the remotes [Cursor to the above conditions. ] and [Cursor ] keys to change them

THX AUDIO SETUP THX Surround EX creates a sixth, center-back channel intended for reproduction by one or more loudspeakers located behind the listening area. With recordings bearing the Dolby Surround EX mark, this delivers a specifically engineered center-back channel that is encoded into the left/right surround channels-precisely as the center channel was encoded into the left/right front channels in matrix-encoded Dolby Surround mixes. However, the THX Surround EX processing will often produce a useful center-back effect even from software that was not, originally, deliberately encoded for EX playback. BASS LIMITER The S170i incorporates a Bass Limiter that you can set to eliminate any chance of your subwoofer producing audible distortion. You will do this by auditioning a built-in test-noise signal the S170i sends to your subwoofer, and increasing the Bass Limiters headroom setting to the point of audible distortion. The Bass Limiter now prevents any program-material signals exceeding this level from being sent to the subwoofer. CONFIGURING THE BASS LIMITER From the <THX Audio setup> menu, use the remotes [Cursor ] and [Enter] keys to select the <Bass limiter setup> item. Using the same keys, set <Bass limiter> to On and <Limiter noise> to On; you will hear a soft rumbling from your subwoofer. (If you do not hear sound from the sub, check your subwoofer audio and power connections, check Speaker Setup, below, and/or check the subwoofers own hardware control settings) Now use the remotes [Cursor ] keys to move to the <Limiter level> item, and [Cursor ] to decrease the limiter setting by 1 dB increments. As you do, the test-noise from the subwoofer will increase in level. Listen for the point at which audible distortions (harshening, clacking, chuffing, or other extraneous elements) become evident, then use [Cursor ] to return (increase) the limiter level by 1 or 2 dB until the distortion ceases. This establishes the distortion-free limit for your current subwoofer setup. It is advisable to return and re-check your Bass Limiter setup after you have completed the Level Setup routines (see below). Even after the Bass Limiter is set you may usefully engage its test-noise to search and destroy the room-rattles that are inevitably excited by high-level subwoofer output. (Window-treatments, electrical wall-plates, and hanging artwork are three common sources.) Should you ever change subwoofers, or reposition your current subwoofer or listening position, you should repeat the Bass Limiter setup routine. With a high-performance subwoofer, this routine can get rather loud. It is often best to await an opportune moment when spouses/children/pets are not at home to perform Bass Limiter setup fully.

BOUNDARY GAIN COMPENSATION This THX Ultra 2 feature compensates for the audio gain (level increase) when the subwoofer is placed against a wall or near a room corner. ENGLISH 21 SVENSKA PORTUGUS ITALIANO ESPAOL DEUTSCH FRANAIS NOTE This feature is only applicable when using a THX Ultra 2 certified subwoofer for which the frequency response and sensitivity are part of the specification. Select <THX Ultra2 Sub> using the remotes [Cursor ] keys, then select <Yes> or <No> using the remotes [Cursor ] keys. Then using the remotes [Cursor ] keys select <Boundary gain comp.>, then select <On> or <Off> using the remotes [Cursor ] keys. NOTE Boundary gain compensation can only be selected if the <THX Ultra2 Sub> menu item is selected to <Yes>. ASA This THX feature adjusts the gain and delay of the Back Surround speakers to compensate for their physical location in the listening room. Choose from three possible locations: together, close, or apart. NOTE You must have two (7.1) Back Surround speakers for this feature to work.

USING THE S170i

You may operate the S170i preamplifier equally from its front panel or via the HTR 2 remote controller. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure to read the section, Front Panel Operations, below. SELECTING SOURCES From the HTR 2 select[AMP]; then use the numeric keys [1 - 10+] also labelled in the same color red as the [AMP] key for [DVD], [SAT], [VCR], VIDEO ], etc. to select directly those sources. NOTE THAT: When an audio-only source is selected, the most recently-selected video signal remains selected, until another audio-video input is selected When you change sources, the OSD will, depending on the Display setup settings (above) momentarily show information about the new input. The level of detail depends on the setting of the <Temporary disp.> item: Full will show all information about the newly selected inputs audio, digital, and video signals; Simple will show only the new input name, and Off will prevent any display from appearing. A newly selected inputs listening mode (Stereo, EARS, Dolby Digital, etc.) will revert to the mode that was employed the last time that input was chosen, except that a multi-channel digital source (Dolby Digital or DTS) source will automatically switch to 5.1/6.1-channel surround, even if the input was last used in another mode such as Stereo or EARS. The Ext5.1 input participates in the S170is source rotation like any other audio-only source. However, since the Ext5.1 input is a straight-through source it does not receive bass-management, tone-control, or any other preamp functions; signals appearing at the rear panels EXTERNAL 5.1 INPUTS pass directly to the corresponding six of the PREAMP ANALOG 7.1 OUTPUTS jacks with no processing other than master-volume control. Bass-management and any other desired processing should be performed by the multichannel external source component. There is an adjustable INPUT LEVEL CONTROL for the analog sources with an INPUT LEVEL METER to make adjustment easy and accurate. This circuit will automatically adjust the individual input to prevent overload of the A/D converter (converter of analog signals to digital, for surround processing) and does not require the user to make any adjustments. But you may want to adjust the input level manually so that each source plays at the same subjective loudness level. Since the automatic adjustment only looks at peak signals, sources with a wide dynamic range (classical music CDs) will sound subjectively softer than sources with a narrow or compressed dynamic range (rock music radio broadcasts). To adjust INPUT LEVEL, first enter the OSD (On Screen Display) by pressing the RIGHT CURSOR KEY and scroll down to SOURCE SETUP with the DOWN ARROW KEY and press ENTER. PORTUGUS SVENSKA 22 From the SOURCE SETUP MENU select ANALOG SENSITIVITY and use the RIGHT/LEFT CURSOR KEY to adjust the INPUT LEVEL. The range of adjustment is -5dB to +10dB. You can also select ANALOG MON to view a vertical bar graph display (with Peak Hold function) of input level. In this mode use the UP/DOWN CURSOR KEY to expand the meter scale from -20dB to 0dB, to -40dB to 0dB. ENGLISH FRANAIS DEUTSCH ESPAOL ITALIANO

DOLBY EX, DTS ES, THX EX, SURROUND 6.1 Multichannel digital recordings (Dolby Digital or DTS) are reproduced via the full suite of front, surround, and one or two back-channel speakers (if selected in <Speaker Setup>). If Dolby Digital EX/DTS ES encoding is present in the original recording its logic is used to derive the back channels; otherwise, the S170i preamplifier derives a single back-channel signal from the left/right surround channels. DOLBY PRO LOGIC Surround-encoded recordings (and stereo recordings that are not encoded ) are reproduced with Pro Logic Dolby Surround decoding, with output to left, center-, and right-front channels and a single monaural surround signal sent to both surround-channel speakers; the surround channels response is rolled off above 7 kHz to discourage localization of surround-speaker locations in DPL mode). Pro Logic mode is best reserved for surround-encoded recordings intended for Dolby Surround or compatible-system reproduction. These include most films on videotape and many on LaserDisc, television/cable programming produced for surround-sound, and most older LaserDiscs. Most DVD recordings, even those that do not exploit multichannel surround, include a Dolby Digital and/or DTS soundtrack in 1- or 2-channel modes; where available, this will usually deliver better performance. With rare exceptions, NADs proprietary EARS listening mode will produce superior results from stereo music recordings than will Pro Logic. DOLBY PRO LOGIC II MOVIE Similar to Dolby Pro Logic, this improved algorithm applies logic after the matrix decoding, rather than before as in Pro Logic, improving image stability and the precision of signal steering. Surround channels are also run full range. DOLBY PRO LOGIC II MUSIC Fine tuned for listening to music, in this mode the surround channels response is rolled off to simulate the acoustic absorption of a typical room. In addition, there are several adjustments that can be made to enhance the listening experience: PL II Panorama When selected the Panorama setting wraps the sound of the Front Left and Right speakers around you for an exciting effect. PL II Center Width Center Width allows you to gradually spread the Center channel sound into the Front Left and Right speakers. At the widest setting all the Center speaker sound is mixed to the Left and Right speakers. This control may help achieve a more spacious sound, or a better blend of the front image. PL II Dimension Dimension adjusts the front/back balance to taste. DTS NEO:6 CINEMA Surround-encoded recordings (and stereo recordings that are not encoded ) are reproduced with DTS Neo:6 Surround decoding, with output to left, center-, and right-front channels, and surround and surround back channels (if selected). DTS NEO:6 MUSIC This music surround mode can be used to create a convincing surround sound experience using front, center, and all selected surround speakers from any 2 channel stereo source. Neo:6 allows the user to adjust the Center Image in six steps. Center Image allows you to gradually spread the Center channel sound into the Front Left and Right speakers.

MACRO COMMANDS A macro command is a series of two or more (up to 64) remote codes issued automatically from a simple two key-press procedure. You might use a macro to automate a simple command sequence, such as, Turn on the DVD player and then press play. Or you might compile an elaborate macro to power up an entire system, select a source, choose a Listening Mode, and begin playback-again, all from a single key-press. The HTR 2 can store one macro on each of its function keys (these exclude the Device Selector keys). NOTE Macros are independent of the currently selected device. RECORDING MACROS To record a macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR 2 function key to which you wish to assign the macro; the status LED turns green. The macro button will also light up. Now, press the sequence of Control function keys to be recorded into the macro, being sure to first press the requisite Device Selector key for each function (you may switch devices while recording the macro as many times as necesarry). This allows you to create a macro containing commands from more than one Device. When you have finished entering the desired command sequence, press [MACRO] again to store the macro; the Learn LED and [MACRO] key illumination will turn off. NOTE Each macro can store a maximum of 64 command steps. If you exceed this number, the macro will be stored automatically after the 64th command is added. Example: Record a Macro to the [0] key to Turn on the NAD receiver, Turn on the DVD player, Select the DVD Input, and Commence Playback: On the HTR 2, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns steady green. Press [AMP]; press [ON]; press [DVD]; press [ON]; press [AMP]; press [1] (red DVD); press [DVD]; press [play] (the Device Key blinks as each step is added). Press [MACRO] again to exit the macro-record mode. To clear a macro, perform the above steps without entering any functions. EXECUTING MACROS To execute a macro, press and release [MACRO]; its key illumination lights for 5 seconds. While it remains lit, press an HTR 2 key to which a macro has previously been stored ([0] as in the case illustrated above). The corresponding macro will run; as each step executes, its parent Device Selectors key flashes lights briefly; when execution is finished, the [MACRO] key illumination goes out. Pressing any other HTR 2 key while a macro is executing will abort the macro. Remember that you must hold the HTR 2 so that its infrared emitter can activate the target components. NOTE When a macro executes, a 1 second delay is automatically inserted between its commands. If you need more than a 1 second delay between particular commands-for example, to permit a component to power up completely-you can record empty steps into the macro. For example, if the [TITLE] key is not used for your CD player, you could record that command into the macro to insert a delay. KEY-ILLUMINATION TIME-OUT The HTR 2s key-illumination can be set to remain lit for 0-9 seconds. The default value is 5 seconds. To set the illumination time-out, simultaneously press-and-hold for 3 seconds both the HTR 2s [DISP] and the [0-9] key, with the digit corresponding to the desired time-out duration; the Learn LED will flash twice to confirm the new setting. When set to zero, the illumination will not turn on at all. NOTE Key illumination is the biggest drain on the HTR 2s batteries. A short key-illumination time-out will extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further.

FACTORY RESET The HTR 2 can be reset to its factory state, deleting all learned commands, copied and punched-trhough keys, macros, and other setup information, reverting all keys to their pre-programmed library commands. To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 2s [ON] and [RTN] keys; the Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the Learn LED will turn red, indicate the remote has been reset. NOTE You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not reset; should this occur, repeat the full procedure. DELETE MODE The HTR 2 can store learned, copied, and default library commands on any single key. (The default library commands are the pre-programmed NAD codes, such as the native NAD receiver commands on the [AMP] page.) You can delete commands by layers back down to the default library command on any key, removing learned commands, punched-through functions, and copied keys. NOTE The default library commands cannot be deleted, so you need not worry that using Delete Mode might cause irreparable changes. To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired keys Device Selector key and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wish to delete; the Learn LED flashes; the number of times indicates which type of function has become activesee the table below. Press the active Device Selector key again to exit Delete Mode. Flashes 3 Command Type Default Library Command Copied Library Command Learned Command
