Optional components
There is no sound.
• Refer to General item “There is no sound.” on
page 47 and check the condition of the system.
• Connect the component properly (see page 45)
while checking:
– if the cords are connected properly.
– if the cord plugs are firmly inserted all the way.
• Turn on the connected component.
• Refer to the operating instructions supplied with
the connected component and start playing.
The sound is distorted.
• Set the volume of the connected component
lower.
The sound from the component connected to the
AUDIO IN MD (VIDEO) jacks is distorted.
• If “VIDEO” appears when you press
FUNCTION repeatedly, switch the function to
“MD” (see the tip for “Listening to audio from a
connected component” on page 46).
Tuner
Severe hum or noise/stations cannot be
received.
• Set the proper band and frequency (see page 33).
• Connect the antenna properly (see page 9).
• Find a place and an orientation that provide good
reception, then set up the antenna again. If you
cannot obtain good reception, we recommend
you connect a commercially available external
antenna.
• The supplied FM lead antenna receives signals
along its entire length, so make sure you extend
it fully.
• Locate the antennas as far away from the speaker
cords as possible.
• Consult your nearest Sony dealer if the supplied
AM antenna has come off the plastic stand.
• Try turning off surrounding electrical
equipments.
A stereo FM program cannot be received in
stereo.
