TRANSMIT WITH SCAN ON
When operating in Scan mode, the radio transmits on the channel
selected by the Channel Selector knob.
Select a transmit channel by turning the Channel Selector knob.
Press and hold the PTT switch and talk in a normal voice. When the PTT
switch is released, the radio continues to monitor the selected channel
for the preset scan delay time before it resumes scanning.
Talkback Scan
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.
Talkback Scan will not work if Priority Scan is also on and your radio is
programmed to always transmit on the Priority 1 channel.
CHANGE THE SCAN LIST
The radio can be programmed to enable the user to add or remove
channels from the scan list. If user changes are enabled, follow these
steps to change the scan list:
Turn Scan and Priority Scan off.
Select a channel to be added or removed from the scan list by turning
the Channel Selector knob. If the channel is already on the scan list,
SCN appears in the display.
Press and hold the SCN button for more than 1 second to toggle the
channel on or off the scan list.
PRIORITY SCAN
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.
When Priority Scan is on, the PR annunciator illuminates, and the display
flashes SCN (alphanumeric mode) or two flashing bars (numeric mode).
If a message is received on a priority channel, the Priority indicator
illuminates, and the radio receiver locks onto that channel for the
duration of the transmission, unless a higher priority channel interrupts.
Priority Scan can be used in combination with Code Guard with:
Priority Scan on (arrow appears above PRI button)
Code Guard Disable off (no arrow above CG button)
The priority channel(s) programmed 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 Code Guard value
is present. If the signal contains the proper Code 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.
DUAL PRIORITY SCAN
In each group, up to two of the sixteen channels can be designated as
priority channels. These two, PR1 and PR2, are periodically tested for
activity, even if a different transmission is being listened to. Activity on
PR2 preempts activity on any of the non-priority channels. Receptions
on PR1 have priority over any other channel in the group, 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 transmit on the first priority channel, transmissions will occur on PR1,
if PR1 isn’t programmed OFF, when operating in Dual Priority Scan
mode.
If PR1 is a fixed channel, and changes to the 1
st
priority channel are
allowed, the user can move the channel selector to a new channel and
press and hold the PRI button for more than 1 second to choose a new
PR1 channel.
Dual Priority Scan is automatically disabled when Group Scan is on.
