AUTION

you are cautioned that any change or modifications not pressly approved in this manual could void your authority operate this equipment.

Precautions

On safety

• Operate the unit only on 120 V AC, 60 Hz.
• The name plate indicating operating voltage, power consumption, etc. is located on the rear of the unit.
• Should any solid object or liquid fall into the unit, unplug it and have it checked by qualified personnel before operating it any further.
• Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself.
• One blade of the plug is wider than the other for the purpose of safety and will fit into the power outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer.

On installation

• Place the unit on a level surface.
• Do not install the unit in a location near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.
• Good air circulation is essential to prevent internal heat buildup in the unit. Place the unit in a location with adequate air circulation. Do not place the unit on a soft surface.

On cleaning the cabinet

Clean the cabinet, panel and controls with a soft cloth lightly moistened with mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

On repacking

Do not throw away the carton and the packing material. It makes an ideal container to transport the unit in.

For the customers in the U.S.A.

For detailed precautions, see the leaflet "IMPORTANT SAFEGUARD".

If you have any question or problem concerning your unit, please consult your nearest Sony dealer.

CAUTION

TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS POLARIZED AC PLUG WITH AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.

Connections

Location of Controls

- Connect the AC power cord last. Make sure power is off. - Cord plugs and jacks are color coded. Red plugs and jacks are for right channel (R) and white ones for the left channel (L) - The cable connectors should be fully inserted into the jacks. A loose connection may cause hum and noise. - Keep speaker cords, connecting cords and power cords away from the AM loop antenna and the tuner's antenna lead-in to avoid possible noise pickup.

To change the AM tuning interval The AM tuning interval is preset at the factory to 10 kHz to match the frequency allocation system of your country. To change the interval, proceed as follows. 1 Press the POWER switch to turn on the unit. 2 Set the BAND FM/AM selector to AM. 3 Press the POWER switch to turn off the unit. 4 Hold the TUNING knob in the "+" position, and then press the POWER switch to turn on the unit. To reset the interval, follow the same procedure. Note When the interval is changed, all stored stations will be erased from the memory. After changing the interval, be sure to store the stations again.

Tuning in Automatically Before reception, be sure to connect the supplied AM and EM antenna

Storing Station Frequencies into Memory

How many stations can be stored? Up to 10 stations can be stored in any order for each alphabet (A. B. C). Therefore, 30 stations can be stored in total If you cannot store a station successfully You can store a station only while "MEMORY" is displayed. If the "MEMORY" indicator has gone off, press MEMORY again How long does a station remain stored? • Storing a new station on a used code erases the previously stored one. • The stored station is maintained for approximately one month even if the power remains off.
How long does a station remain stored? a. Spring a new station on a used code era
previously stored one.
• The stored station is maintained for approximately one

Tuning into a Stored Station Directly

Which stations are skipped during memory scanning? The memory scan will skip stations which have a very weak signal. If you cannot scan successfully Turn the TUNING knob while the code indicator is flashing. If the flashing has stopped, press MEMORY SCAN again

Troubleshooting

Before going through the check list below, first refer back to the connection and operating procedures. Should any problem persist after you have made these checks, consult your nearest Sony dealer.

Trouble	Cause	Remedy
No sound.	Switches of the amplifier are wrongly set.	Set them correctly.
Unable to receive stored stations.	Frequency is incorrectly stored.	Store the correct frequency.
STEREO indicator blinks.	Antenna direction and location are not correct.	Check the setting of antenna.
	Different frequency is used from that of the broadcasting station.	Set to the correct frequency.
	Signal is too weak.	Connect an external antenna for FM.
Too many noises.	Picking up noises from other electrical apparatus.	Move the tuner and antenna lead-in wire away from the noise sources.
	Antenna direction and location are not correct.	Check the setting of the antenna.
	Antenna wire collects unnecessary radio waves or noises.	Replace it with a coaxial cable.
	There are working TVs, transceivers and amateur wireless units in the vicinity.	Do not use noise-producing apparatus near the tuner.
	One antenna is used for more than two tuners, or with a TV set.	Use a distributor.
Unable to scan stored stations.	TUNING is not operated.	First press MEMORY SCAN and then turn TUNING.
