Tuner
The FM reception is poor.
• Use a 75-ohm coaxial cable (not supplied)
to connect the receiver to an outdoor FM
antenna as shown below. If you connect
the receiver to an outdoor antenna, ground
it against lightning. To prevent a gas
explosion, do not connect the ground wire
to a gas pipe.
Radio stations cannot be tuned in.
• Check that the antennas are connected
securely. Adjust the antennas and connect
an external antenna, if necessary.
• The signal strength of the stations is too
weak (when tuning in with automatic
tuning). Use direct tuning.
• Make sure you set the tuning interval
correctly (when tuning in AM stations
with direct tuning).
• No stations have been preset or the preset
stations have been cleared (when tuning by
scanning preset stations). Preset the
stations (page 56).
• Press DISPLAY repeatedly on the receiver
so that the frequency appears on the
display.
Remote commander
The remote does not function.
• Point the remote at the remote sensor on
the receiver.
• Remove any obstacles in the path between
the remote and the receiver.
• Replace all the batteries in the remote with
new ones, if they are weak.
• Make sure you select the correct input on
the remote.
• The AUX button on the remote are not
available for receiver operation.
• When you operate a programmed non-
Sony component, the remote may not
function properly depending on the model
and the maker of the component.
Error messages
If there is a malfunction, the display shows a
message. You can check the condition of the
system by the message. Refer to the following
table to solve the problem. If any problem
persists, consult your nearest Sony dealer.
If an error message appears while you perform
Auto Calibration, see “Error and warning
codes” (page 33) to solve the problem.
DEC. EROR
Appears when a signal the receiver cannot
decode (ex. DTS-CD) is input and “DEC.
PRI.” in the AUDIO menu is set to “DEC.
PCM”. Set it to “DEC. AUTO” (page 42).
PROTECT
Irregular current is output from the
speakers. The receiver will automatically
turn off after a few seconds. Check the
speaker connection and turn on the power
again.
