Notes

•

The attenuator is very effective at reducing strong signal overload interference when using the scanner in areas close to cellular telephone transmitting facilities, like the tower shown on Page 67.

•

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 will apply 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.
