SYSTEM SCAN
22
display always changes to the system of the call and usually changes to
the group of the call. The selected system or group can be changed while
scanning by simply pressing the system or group select switch. Scanning
then halts and the selected system or group changes. Scanning resumes
1 second after a switch is released.
Some transceivers may be programmed so that the conventional and
some Multi-Net systems may not be scanned. If this is the case with your
transceiver, your system operator will tell you which systems are not
scanned.
Scan Resume Delay
After a message is received or transmitted in the scan mode, there is
a delay period of 1-7 seconds before scanning resumes. The exact length
of this delay is programmed by your system operator. When a message is
received, this delay prevents another message from being received before
a response can be made. If a response is not made during this delay
period, the selected system and group may have to be changed (refer to
next section). When a message is transmitted, this delay ensures that a
response to your message is heard instead of some other message occur-
ring on another system or group.
Transmitting In Scan
When you transmit while scanning (dashes in both the system and
group displays), the transmission always occurs on the revert system/
group. This is the system and group that were displayed when scanning
was turned on. To display the revert system and group while scanning,
temporarily halt scanning by pressing the SCN key, Auxiliary switch, or
PTT switch. If a message is received while scanning, scanning stops and
the system and group of the call are displayed. If the transmitter is keyed
to respond to this call, Floating/Fixed Revert programming determines
the system and group on which the transmission occurs:
Floating - When Floating Revert is programmed, you can always
respond to the call without having to change the selected system/
group as long as you do so before the scan resume delay expires (see
