An important note about your radio !
Some of the radio/button functions discussed next will only operate in
your radio if so programmed by your dealer, or after the installation of
certain internal optional units. In this way, the radio’s operation can be
simplified and customized specifically for the user according to net-
work requirements. If pressing a button on your radio does not result
in the same function described in this manual, or if you are uncertain
of the functions your particular radio is configured with, contact your
dealer. See “

Scanning
Scanning allows you to sequentially check for calls on all or only those
channels you select. To start scanning, Pressing and holding the
S/DW
button more than 2 seconds (but less than 4 seconds). A beep then sounds
and the display will clear and show “
SCAN
”. Scanning will pause when a
signal is received, at which time the channel number (or alphanumeric
tag) will be displayed. A small “
S
” will be displayed above the channel,
indicating the scanner is still active, but paused.
During this pause, you can press the
PTT
switch and talk to the station.
Otherwise, scanning will resume a few seconds after the signal is no longer
present. While scanning, if you momentarily press the
PTT
switch, opera-
tion automatically shifts to a default channel. This default channel can be
set to the priority channel (both “
P
” and “
S/DW
” are displayed), last-
busy channel, or home channel, depending on how your radio was pro-
grammed .
To stop scanning, simply press
S/DW
momentarily again. Operation will
return to the channel that was last selected when scanning was activated.
If enabled by dealer programming , you may select only the channels you
want to scan, and have others skipped-over by performing the following
routine.
Turn the radio OFF, then depress the S/DW button while turning the radio
back ON again. “
