■ Preamp and attenuator

The preamp amplifies received signals in the receiver
input (front end) circuit to improve the S/N ratio and
sensitivity. Turn this function ON when receiving weak
signals.
The attenuator prevents a strong undesired signal
near the desired frequency or near your location,
such as from a broadcast station, from causing dis-
tortion or spurious signals.
Push [P.AMP/ATT] momentarily to turn the preamp
ON and OFF; push and hold for 1 sec. to turn the at-
tenuator ON.
