Problems and remedies (continued)
Tuner
There is severe hum or noise ("TUNED" or
"STEREO" flashes).
• Set the proper band and frequency (see page 13).
• Connect the antenna properly (see page 7).
• 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 wire 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 wire has come off the plastic stand.
• Try turning off surrounding electrical equipment.
A stereo FM program cannot be received in
stereo.
• Press FM MODE on the remote until "MONO"
disappears.
• See "There is severe hum or noise ("TUNED" or
"STEREO" flashes).", and check the antenna
condition.
