Part No. 001-7600-001
The scan lists are user programmable if the
key is available. Pressing this key changes the
status of the displayed channel in the current scan list
only. The display indicates “SC ON” if the channel
was just added to the scan list and “SC OF” if it was
just deleted. In addition, the scan list status is indicated
by the decimal point in the display. This indicator is on
when the displayed channel is scanned. The decimal
point flashes when scanning is occurring.
The scan list status of a channel can be changed
while scanning only when listening to a message on
the channel. The current status of all the lists is stored
in memory. Therefore, the status of the various scan
lists does not change when power is turned off.
3.6.3 PRIORITY CHANNEL SAMPLING
Priority channel sampling ensures that messages
on priority channels are not missed while listening to
messages on other channels. If priority sampling is
used, a priority A channel is designated by program-
ming. If the key is available, pressing that key
selects the priority A channel. This key also may be
programmed so that if it is pressed and held, the prior-
ity A channel changes to the current channel.
Sampling of the priority A channel occurs only
when scanning is enabled. It does not occur while
transmitting. When the priority channel is sampled
while listening to a message on another channel, a
series of “ticks” are heard. These ticks are brief inter-
ruptions of the audio signal that occur while the trans-
ceiver changes channels to check the priority channel.
Another priority channel also can be programmed
that can be quickly selected by the key. This
channel is programmed only to allow quick selection
and is not sampled while listening to a non-priority
channel.
