casts.
Transmitting station is too far away.
9 Try reducing the treble sound by using the treble con-
trol.
© Try changing the location, height and/or direction of
the antenna.
e if an indoor antenna is being used, change to an out-
door antenna.
© Try using an antenna with more elements.

While listening to AM broadcasts
Nearby building or mountain.
@ Try changing the location, height and/or direction of

Problems noted at all times
Unit is being used at the same time as the televi-
sion set.
Interference from adjacent broadcast signals.
The AM loop antenna connection wires are too
close to the power cord.
The power supply frequency from the power cord
is modulated and heard from the speakers.
© Turn off the television set, or use this unit farther
away from it.
© Try reducing the treble sound by using the treble con-
trol.

less than the indicated rated impedance of this unit
are used or under severe use, such as loud vol-
ume, excessive power and in an excessively hot
environment.
® Switch off the power, and after determining and cor-
tacting the cause, switch on the power once again.
