works according to the channel settings.
• When CTCSS/DCS is on in Chain Search, Fine Tune, or Signal Stalker
I, the scanner searches for CTCSS/DCS codes.
• The CTCSS/DCS feature does not apply to the AIR band or Weather
Scan.
For more information, see
“Programming CTCSS/DCS Codes”
on p. 60.
Setting Priority
The priority feature lets you scan through the channels and still not miss
important or interesting calls on specific channels. You can program one
stored channel in each bank as a priority channel. If the priority feature
is turned on, as the scanner scans the bank, it checks that bank’s priority
channel for activity every 2 seconds.
The scanner automatically designates each bank’s first channel as its priority
channel. Follow these steps to select a different channel in a bank as the
priority channel.
1. From Manual Mode, press ENT/PGM .
2. Enter the channel number you want to select as the priority channel, and
then press
PRI .
“P”
appears to the left of the selected channel frequency.
