Scan; Talkback - Motorola PM400 User Manual

SCAN

Your radio is equipped with the Scan feature,
which allows you to search for, lock onto, and
monitor voice activity on channels/talkgroups.
Scan lists are assigned per channel/talkgroup,
by your dealer/programmer. Your radio
automatically switches to a channel/talkgroup,
within that scan list, when it detects activity.
You can also edit these lists through your
radio's menu (see page 36).
• The green LED indicator blinks during scan
mode; it stops blinking when the radio
switches to an active channel/talkgroup.
• The Gsymbol appears on the display
while in scan mode.
• Your dealer/programmer can preprogram
your radio where if the microphone is taken
off-hook while in Scan mode, the scanning
activity becomes suspended until the
microphone is replaced.
There are two ways that your radio scans:
• System Scan (manual)
• Auto Scan (automatic)

TALKBACK

The Talkback feature allows you to respond to
a transmission while scanning. If transmission
is detected on a channel/talkgroup while
scanning, the radio will stop and land on that
channel/talkgroup for a preprogrammed period
of time after activity has ceased. This is
referred to as "hangtime". During this hangtime
you may respond by pressing the PTT button.
Note: The LED scan indicator stops blinking
while the radio is in hangtime. If the PTT
button is not pressed during the prepro-
grammed hangtime, the radio reverts
back to scan.
