Scanning
This feature will support three different scanning types. Dealer programming enables the required
scan type.
Normal Scan
Priority Scan
Priority Look-back
The user activates scanning by a short press on the Pre-programmed Scan button, once the radio
has enabled scan, it will traverse through the pre-programmed scan list. The time spent on
receiving a channel in the scan list is referred to as the Scan Speed Time (programmable from
0.05sec to 2.0sec in 0.01sec increments). When an incoming call is detected and decoded,
scanning stops and the radio will un-mute. After the call has ended, the radio enters Scan Delay
/ Wait Time Mode for a pre-programmed period of time (0 to 15 seconds in 1-second
increments). If the radio receives a call from the same caller before the Scan Delay expires, the
radio will re-enter the Scan Delay Mode and that period of time will reset. If the user is permitted
to respond to the caller, the Scan Delay will be reset. When the Scan delay expires, the radio
resumes scanning.
Normal Scan
Any number of channels can be entered into the scan list. This will be equal to or less than the
number of programmed channels. The flashing green LED will stop when ‘CARRIER’ or ‘CARRIER
AND CORRECT TONE’ is detected. During scan delay, the LED shall remain clear. When Scan
Delay expires and Scan Speed resumes, the LED shall also resume flashing green.
Basic Radio Operation
Priority Scan
A priority channel can be allocated using the PM200/250 programmer. The priority channel will be
part of the list of channels that make up the scan list. The priority channel when used with other
scanned channels will operate as follows:
P1→S1→P1→S2→P1→S3→P1→S4→P1, etc.
Priority Look Back Scan
One channel can be programmed by the dealer to be the Priority channel, which will enable
‘Look-Back’. Pressing the Scan button shall activate Priority Look-Back. The Priority Look-Back
causes the radio to periodically ‘Look-Back’ to the priority channel for the presence of a carrier
regardless of the channel that the user may be on. The frequency that the radio will ‘Look-Back’
