Beyond the Basics
•The attenuator is very effective at reducing strong signal overload interference when using the scanner in areas close to cellular telephone transmitting facilities.
•If you turn on the attenuator, the scanner might not receive weak signals.
•Activating the normal attenuator mode on a Motorola or APCO Project 25 trunking control channel applies attenuation to all calls received on that trunking system. You can press ATT during a trunking call or while manually tuned to a system control channel to toggle attenuation on or off for the trunking system.
