will become active for voice communication after the tone
sequence is complete.
Tone encode will be transmitted with Channel Guard,
if one is defined, and tones are always transmitted in
clear voice mode, even if the channel is set for digital or
private (see
VOICE MODES
). Digital or private voice
transmission will resume normally after the tone trans-
mission.
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 pro-
gramming) whether or not it is in the scan list. Each
conventional system’s channel scan list is retained in
memory when the radio is turned off or when the battery
pack is removed.
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 decoding en-
abled. Fewer channels will result in a faster scan rate. If
programmed 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 receives 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-pri-
ority channel is being received, the display name is
updated, or comes on and the received channel is
