Scan Modes
Scanning is a Dealer programmable feature that allows you to monitor
a number of channels. Your Dealer will help you define a channel
"scan list" to be programmed into a scan channel (any channel, 1-4 on
model SP-130) or (any channel, 1-16 on model SP-140). Once that
channel location is selected, scan is initiated.
Normal Channel Scan
Once the scan list is programmed you can initiate scan. Simply
move the channel selector knob to the scan channel position
and the radio will start to scan. The top panel LED can be
programmed to flash green as the radio is scanning.
If a conversation is detected on any of the channels in the scan
list, the radio will stop on that channel and you will be able to
hear the conversation. If programmed for normal scan TX you
will be able to transmit on that active channel during the pro-
grammable scan delay time. The scan delay time is the amount of
time the radio will stay on that channel once activity has ceased
(Dealer programmable, 4-7 seconds is typical). The radio will
resume scanning once the scan delay time has expired. Scanning
will continue until the channel is changed.
Priority Channel Scan
A single channel may be programmed as the "Priority" channel.
The radio will constantly monitor this channel while scanning
and when the radio has stopped on an active channel. If a call
is detected on the "Priority" channel, the radio will automatically
move to, and remain on, the "Priority" channel for as long as the
priority conversation takes place. "Priority" channel activity takes
precedence over all other conversations.
NOTE: "Priority" channel scan and "look back" require that the
radio leave the active channel for a fraction of a second (at regular
intervals) to check the priority channel for a message. Depending
upon how the radio is programmed (scan speed, etc.) this may or
may not be noticeable as "breaks" on the active channel for that
ssame fraction of a second.
