Scanning Conventional Channels

Channels which have been previously added to the scan list on a per system
basis may be scanned. The selected channel is scanned (if enabled through
programming) whether or not it is in the scan list. Each conventional sys-
tem's channel scan list is retained in memory when the radio is turned off.
The scan rate will vary depending upon the number of channels in the scan
list and whether or not the radio is programmed to scan for channels with de-
coding enabled. Fewer channels will result in a faster scan rate. If pro-
grammed for dual-priority scan operation, the priority-one, priority-two and
the remaining scan list channels are scanned. Once a signal is detected and
the correct encoded squelch signal is decoded (if programmed), the radio re-
ceives the message and displays the received scan channel. At the same time,
scanning continues on the priority-one and priority-two channels. Should the
priority-one or priority-two channel carrier, regardless of encoded squelch
decoding, be detected while a non-priority channel is being received, the dis-
play name is updated and the received channel is switched to the priority
channel. Scanning of the priority-one channel will continue if a message is
being received on the priority-two channel.
Adding Channels To A Scan List:
