Before you get started

Turn off the power to all components before making any connections. Do not connect the AC power cord until all of the connections are completed. Be sure to make connections firmly to avoid hum and noise. When connecting an audio/video cord, be sure to match the color-coded pins to the appropriate jacks on the components: yellow (video) to yellow; white (left, audio) to white; and red (right, audio) to red. When you connect optical digital cords, insert the cord plugs straight in until they click into place. Do not bend or tie the optical digital cord.

Using the Radio Data System (RDS)
This receiver also allows you to use RDS (Radio Data System), which enables radio stations to send additional information along with the regular program signal. You can use the following convenient RDS features:
Displaying RDS information Scanning preset stations by program type
If there is an emergency announcement by government authorities, ALARM flashes in the display. When the message consists of 9 characters or more, the message scrolls across the display. If a station does not provide a particular RDS service, NO XXX (such as NO PTY) appears in the display.
Scanning preset stations by program type
You can tune in preset stations according to a program type that you specify. The receiver scans for stations in its preset memory currently broadcasting the specified program type.
Note that RDS is operable only for FM stations.*
* Not all FM stations provide RDS service, nor do they provide the same types of services. If you are not familiar with the RDS services in your area, check with your local radio stations for details.

Precautions

On safety
Should any solid object or liquid fall into the cabinet, unplug the receiver and have it checked by qualified personnel before operating it any further.
If you encounter color irregularity on a nearby TV screen
This speaker system is magnetically shielded to allow it to be installed near a TV set. However, color irregularities may still be observed on certain types of TV sets.
If color irregularity is observed.

On power sources

Before operating the unit, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the receiver. The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the receiver itself has been turned off. If you are not going to use the receiver for a long time, be sure to disconnect the receiver from the wall outlet. To disconnect the AC power cord, grasp the plug itself; never pull the cord. (Models of area code U, CA only) One blade of the plug is wider than the other for the purpose of safety and will fit into the wall outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer. AC power cord must be changed only at the qualified service shop.
Turn off the TV set once, then turn it on again after 15 to 30 minutes.
If color irregularity is observed again.
Place the speaker further away from the TV set.

If howling occurs

Reposition the speakers or turn down the volume on the receiver.

On cleaning

Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine. If you have any question or problem concerning your receiver, please consult your nearest Sony dealer.

Troubleshooting

If you experience any of the following difficulties while using the receiver, use this troubleshooting guide to help you remedy the problem. Also, see Checking the connections on page 21 to verify that the connections are correct. Should any problem persist, consult your nearest Sony dealer.
There is no sound or only a very low-level sound no matter which component is selected.

On heat buildup

Although the unit heats up during operation, this is not a malfunction. If you continuously use this unit at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet.

On placement

Place the receiver in a location with adequate ventilation to prevent heat buildup and prolong the life of the receiver. Do not place the receiver near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock. Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions. Use caution when placing the unit or speakers on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result.

On operation

Before connecting other components, be sure to turn off and unplug the receiver.
Check that the speakers and components are connected securely and correctly. Check that both the receiver and all the components are turned on. Check that the MASTER VOLUME control is not set at VOL MIN. Press MUTING to cancel the muting function. Check that the handphones are not connected. The protective device on the receiver has been activated because of a short circuit (PROTECT flashes). Turn off the receiver, eliminate the short-circuit problem and turn on the power again.
There is no sound from a specific component.
There is no sound from the active sub woofer.
Check that the component is connected correctly to the audio input jacks for that component. Check that the cord(s) used for the connection is (are) fully inserted into the jacks on both the receiver and the component. Check that you have selected the correct component on the receiver.
There is no sound from one of the front speakers.
There is no sound output from the SUB WOOFER terminal depending on the sound field (page 58).
The surround effect cannot be obtained.
Make sure the sound field function is on (press MODE).
Dolby Digital or DTS multi channel sound is not reproduced.
Connect a pair of headphones to the PHONES jack to verify that sound is output from the headphones (page 22). If only one channel is output from the headphones, the component may not be connected to the receiver correctly. Check that all the cords are fully inserted into the jacks on both the receiver and the component. If both channels are output from the headphones, the front speaker may not be connected to the receiver correctly. Check the connection of the front speaker which is not outputting any sound.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Unleaded solder Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

LEAKAGE

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
To Exposed Metal Parts on Set
: LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
