XIV. Scan Modes, continued
Normal Channel Scan, continued
channel during the programmable scan delay time. (The scan delay time
is the amount of time the radio will stay on that channel once activity has
ceased. Dealer programmable, 4-7 seconds is typical). The radio will
resume scanning once the scan delay time has expired, and will continue
to scan until the channel is changed. The LED will flash green.
Priority Channel Scan
A single channel may be programmed as the "Priority" channel. The radio
will constantly monitor this channel while scanning and when the radio has
stopped on an active channel. If a call is detected on the priority channel,
the radio will automatically move to, and remain on, the priority channel
for as long as the priority conversation takes place. Priority channel activity
takes precedence over all other conversations. To activate the Priority scan
mode, press and release the scan button (first button below the P-T-T bar).
The LED will flash green.
XV. Other Scanning Features
Look Back
This feature is ideal for those who do not need scan as defined above, but
want to make sure that they never miss a call on the "Priority" channel if
another channel has been selected. Once a channel has been selected,
the radio will periodically "look back" at the priority channel. If activity is
detected on the priority channel, the radio will move to that channel for
as long as it remains active. To enter the "look back" mode, press and hold
the scan button (first button below the P-T-T bar). Lb / Channel number will
be shown in the display, the LED will flash green.
NOTE: Look back requires that the radio leave the current channel for a
fraction of a second (at regular intervals) to check the priority channel for
activity. Depending upon how the radio is programmed (scan speed, etc.)
this may or may not be noticeable as "breaks" on the current channel for
that same fraction of a second. A transmission will be made on the active
channel at all times.
Scan Channel Delete
To temporarily delete a channel from the scan list, simply press the monitor
button (second button below the P-T-T bar) while scanning and stopped on
the channel to be deleted. This will remove that channel from the scan list
