Hooking up the system

Perform the following procedure 1 to 5 to hook up your system using the supplied cords and accessories.

MHC-GX40 only

1. Connect the front speakers.
   Connect the speaker cords to the SPEAKER jacks as shown below.
   

2. Connect the sub woofer speaker. (MHC-GX40 only)
   Connect the speaker cords to the SUB WOOFER OUT jack and SUB WOOFER CONTROL jack as shown below.
   
   Hooking up the system (continued)

3. Connect the FM/AM antennas.
   **** Set up the AM loop antenna, then connect it
   
   
   

4. For models with a voltage selector, set VOLTAGE SELECTOR to the local power line voltage.
   
   Middle Eastern models: 120 – 127 V

5. Connect the power cord to a wall outlet.
   The demonstration appears in the display. When you press ?/1, the system turns on and the demonstration automatically ends. If the supplied adapter on the plug does not fit your wall outlet, detach it from the plug (only for models equipped with an adapter)
   

To connect optional components
See page 24.
To attach the front speaker pads
Attach the supplied front speaker pads to the bottom of the speakers to stabilize the speakers and prevent them from slipping.

Note
Keep the speaker cords away from the antennas to prevent noise.

Placing the sub w oofer (MHC-GX40 only)
Since the human ear cannot detect the direction and position where the bass sound being reproduced by a woofer (below 150 Hz) comes from, you can place the woofer wherever you like in your room. To obtain a better bass reproduction, we recommend you to place the woofer on a solid floor where the resonance is unlikely to occur.

Notes

• Always place the woofer vertically, keeping a few centimeters from away the wall.
• If the woofer is placed in the center of a room, the bass could be extremely weakened. This is due to the influence of the standing wave of the room. If this happened, move the woofer away from the center of a room or eliminate the cause of the standing wave, by placing a bookshelf on the wall, etc

When carrying this system
Perform the following procedure to protect the CD mechanism.

What is the Radio Data System?
Radio Data System (RDS) is a broadcasting service that allows radio stations to send additional information along with the regular program signal. This tuner offers convenient RDS features like station name display and location of stations by program type. RDS is available only on FM stations.*

Note
RDS may not work properly if the station you tuned in is not transmitting the RDS signal properly or if the signal is weak.

• Not all FM stations provide RDS service, nor do they provide the same types of services. If you are not familiar with the RDS system, check with your local radio stations for details on RDS services in your area.

• The record/playback heads are magnetized (see “Demagnetizing the tape heads” on page 28)

The tape does not erase completely.

• The record/playback heads are magnetized (see “Demagnetizing the tape heads” on page 28).

There is excessive wow or flutter, or the sound drops out.

• The capstans or pinch rollers are dirty (see “Cleaning the tape heads” on page 28).

Noise increases or the high frequencies are erased.

• The record/playback heads are magnetized (see “Demagnetizing the tape heads” on page 28).

Tuner

There is severe hum or noise (“TUNED” or “STEREO” flashes in the display).

• Adjust the antenna.
• The signal strength is too weak. Connect the external antenna.

A stereo FM program cannot be received in stereo.

• Press STEREO/MONO on the remote repeatedly until “MONO” disappears.

If other troubles not described above occur, reset the system as follow s:

1. Unplug the power cord.
2. Plug the power cord back in.
3. Press , GROOVE, and ?/1 at the same time.
4. Press to turn on the system. The system is reset to the factory settings. All the settings you made are cleared.

Messages

One of the following messages may appear or flash in the display during operation.

NO DISC

• There is no CD on the disc tray

OVER

• You have reached the end of the CD.

“PROTECT” and “PUSH POWER” appear alternately.

• A strong signal was input. Press to turn off the system, leave the system turned off for a while, then press again to turn on the system. If “PROTECT” and “PUSH POWER” appear alternately even after the system is turned on again, press  to turn off the system and check the speaker cord.

Additional Information

Precautions

On operating voltage
Before operating the system, check that the operating voltage of your system is identical with the voltage of your local power supply.

On safety

• The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

• Unplug the system from the wall outlet (mains) if it is not to be used for an extended period of time. To disconnect the cord (mains lead), pull it out by the plug. Never pull the cord itself.

• Should any solid object or liquid fall into the component, unplug the system and have it checked by qualified personnel before operating it any further.

• The AC power cord must be changed only at a qualified service shop.
  On placement

• Do not place the system in an inclined position.

• Do not place the system in locations where it is

  • Extremely hot or cold
  • Dusty or dirty
  • Very humid
  • Subject to vibrations
  • Subject to direct sunlight.

On heat build up

• Although the system heats up during operation, this is not a malfunction.
• Place the system in a location with adequate ventilation to prevent heat build up in the system.
• If you continuously use this system at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet.
• To prevent a malfunction, do not cover the ventilation hole for the cooling fan.

On operation

• If the system is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lens inside the CD player. Should this occur, the system will not operate properly. Remove the CD and leave the system turned on for about an hour until the moisture evaporates.
• When you move the system, take out any discs.

If you have any questions or problems concerning your stereo system, please consult your nearest Sony dealer.

Notes on CDs

• Before playing, clean the CD with a cleaning cloth. Wipe the CD from the center out.
• Do not use solvents.
• Do not expose the CD to direct sunlight or heat sources

Note on CD-R/CD-RW playback

Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the drive’s characteristics. Besides, the discs, which are not yet finalized at the end of recording, cannot be played back.

Cleaning the cabinet
Use a soft cloth slightly moistened with mild detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded over, break off the cassette tab from side A or B as illustrated. If you later want to reuse the tape for recording, cover the broken tab with adhesive tape.

Before placing a cassette in the tape
deck Take up any slack in the tape. Otherwise the tape may get entangled in the parts of the tape deck and become damaged.
When using a tape longer than 90 minutes
The tape is very elastic. Do not change the tape operations such as play, stop, and fast-winding frequently. The tape may get entangled in the tape deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use. Be sure to clean the tape heads before you start an important recording or after playing an old tape. Use a separately sold dry-type or wet-type cleaning cassette. For details, refer to the instructions of the cleaning cassette.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that have contact with the tape every 20 to 30 hours of use with a separately sold demagnetizing cassette. For details, refer to the instructions of the demagnetizing cassette.
