When to replace batteries
Under normal use, the batteries should last for about 6
months. When the remote no longer operates the
receiver, replace both batteries with new ones.
Before you get started
Notes
• Do not leave the remote in an extremely hot or humid
place.
• Turn off the power to all components before making
any connections.
• Do not connect the AC power cords until all of the
connections are completed.
• Be sure to make connections firmly to avoid hum
and noise.
• When connecting an audio cable, be sure to match
the color-coded pins to the appropriate jacks on the
components: White (left, audio) to White; and Red
(right, audio) to Red.
• Do not use a new battery with an old one.
• Do not expose the remote sensor to direct sunlight or
lighting apparatuses. Doing so may cause a malfunction.
• If you don’t use the remote for an extended period of time,
remove the batteries to avoid possible damage from
battery leakage and corrosion.

If an FM stereo program is distorted
The STEREO indicator flashes. Press FM MODE to
change to monaural (MONO). You will not have the
stereo effect but the distortion will be reduced. To
return to stereo mode, press this button again.
Receiving Broadcasts
This receiver lets you enter a station’s frequency
directly by using the numeric buttons (direct tuning). If
you don’t know the frequency of the station you want,
see “Receiving broadcasts by scanning stations
(automatic tuning)” on this page.
If you cannot tune in a station and the entered
numbers are flashing
Make sure you’ve entered the right frequency. If not,
press DIRECT and re-enter the frequency you want.
If the entered numbers still flash, the frequency is not
used in your area.
Before you begin, make sure you have:
• Connected an FM/ AM antenna to the receiver as
indicated on page 5.
• Selected the appropriate speaker system. (See
“Selecting the speaker system” on page 7.)
To watch FM simulcast TV programs
Make sure that you tune in the simulcast program both
on the TV (or the VCR) and on the receiver.

Tuning preset stations (preset tuning)
Presetting Radio Stations
You can tune directly to a preset station by entering its
preset number. If you don’t know which stations are
preset on which numbers, you can tune by scanning
the preset stations.
You’ll most likely want to preset the receiver with the
radio stations you listen to often so that you don’t have
to tune in the station every time. The receiver can store
a total of 30 FM or AM stations. You can store the
stations on preset numbers combining 3 characters (A,
B, C) and numbers (0 - 9). For example, you can store a
station as preset number A1, B6 or C9, etc.

persist, consult your nearest Sony dealer.
Recording cannot be made.
Check that the components are connected
correctly.
/
There’s no sound or only a very low-level sound is heard.
The remote does not function.
/
/
/
/
/
Check that the speakers and components are
connected securely.
Make sure you select the correct component
on the receiver.
Make sure you set the SPEAKERS selector
correctly.
Press MUTING on the remote if the MUTING
indicator turns on.
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.
/
/
/
/
Point the remote at the remote sensor g on
the receiver.
Remove the obstacles in the path of the
remote and the receiver.
Replace both batteries in the remote with new
ones if they are weak.
Make sure you select the correct function on
the remote.
The left and right sounds are unbalanced or reversed.
/
Check that the speakers and components are
connected correctly and securely.
Adjust the BALANCE control.
/
Severe hum or noise is heard.
/
Check that the speakers and components are
connected securely.
/
Check that the connecting cords are away
from a transformer or motor, and at least 10
feet (3 meters) away from a TV set or
fluorescent light.
/
/
/
Place your TV away from the audio
components.
Make sure you connect a ground wire to the
antenna ground terminal.
The plugs and jacks are dirty. Wipe them
with a cloth slightly moistened with alcohol.
Radio stations cannot be tuned in.
/
/
/
/
Check that the antennas are connected
securely. Adjust the antennas and connect an
outdoor antenna if necessary.
The signal strength of the stations is too weak
(when you tune in with automatic tuning).
Use direct tuning.
Make sure you set the tuning interval
correctly (when you tune in AM stations with
automatic tuning) (see pages 9 and 13).
