Nuisance Channel Delete
If your radio is programmed for Nuisance Channel Delete and Channel
Scan is assigned to a top toggle switch, a Nuisance Channel can be
temporarily removed from the Scan List by sliding up and then back
down. Turn off Scan for at least Þ ve seconds or cycle radio power to
revert to programmed scan list.
Transmitting with Scan On
The radio transmits on the channel selected by the Channel Selector
knob unless Talkback Scan is enabled or “Transmit on Priority 1” is
enabled (see Priority Scan).
When the PTT switch is released, the radio continues to monitor the
selected channel for the preset scan delay time before it resumes
scanning.

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.
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 ß ashes
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 Þ xed channel, tied
to the Channel Selector knob, or programmed OFF. If the radio is
programmed to transmit on PR1, transmissions will occur on the Þ rst
priority channel when operating in Priority Scan Mode.
Priority Scan can be used in combination with Code Guard. If a
message is received on a priority channel, the radio receiver locks on
to the priority channel and checks to see if the proper Channel Guard
value is present. If the signal contains the proper Channel Guard value,
the radio receives the message. Otherwise, the radio will re-check the
channel every 4 seconds, until the activity on the channel ceases.
If enabled the user can use the keypad to change the priority channels.
The Priority Channel selection can be programmed to a programmed
button or as a menu item.
NOTE: To use Zone based Priority Channels set both Global Priority
Channel 1 and 2 to 'OFF'.
