Common Radio Features

PL Defeat

With this feature, you can override any coded squelch (DPL, PL, or network ID) that might be programmed to a channel.

Place the preprogrammed PL Defeat switch in the PL Defeat position. You can now hear any activity on the channel. The radio is muted if no activity is present.

When this feature is active,

the Carrier Squelch statusC indicator (C) will be

displayed.
