■ 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
distortion or spurious signals.
Push [P�AMP/ATT] momentarily to turn the preamp
ON or OFF; hold down for 1 second to turn the
attenuator ON.
