If your radio is programmed for Talkback Scan, press PTT while a channel is
active or while scan delay time remains, you will be responding on the transmit
frequency of the received channel. The ‘RX’ indicator will be shown in the display
while scan delay time remains.
Talkback Scan will not work if Priority Scan is on and your radio is also
programmed to transmit on the Priority 1 channel.
3.5.7 priority Scan (pri)
Priority Scan enables the radio to receive on any channel while monitoring for a message on the
designated priority channel(s). The radio samples each priority channel at a preset rate (.25-2.0
seconds) regardless of activity on any other channel. Priority Scan operates only while the radio is not
transmitting and can be used in combination with scan operation.
Up to two priority channels can be on a radio wide (Global) or per-zone basis, programmable via PC.
When Global Priority channels are enabled, zone priority selections are disabled.
If priority channels are assigned on a per-zone basis, the radio monitors the priority channels in the
currently selected zone. If priority channels are programmed on a Global basis the radio will monitor the
assigned channels regardless of the currently selected zone.

When Priority Scan is on, the display flashes SCN. If a message is received on a
priority channel, the Priority Indicator appears, and the radio receiver locks onto
that channel for the duration of the transmission, unless a higher priority channel
interrupts.
The two channels, designated as PR1 and PR2, are periodically sampled for
activity, even if a different transmission is being monitored. Activity on PR2
preempts activity on any of the non-priority channels. Receptions on PR1 have
priority over any other channel, including PR2.
Either priority channel can be programmed as a fixed channel, tied to the
Channel Selector knob, or programmed OFF. If the radio is programmed to
