setting the scanner to the
trunking mode
simultaneous trunking
The scanner allows you to track up to 10
systems at a time. You can trunk scan or
search and scan conventional frequencies
at the same time. You can also program
conventional frequencies in the same bank
as trunking systems.
After the scanner is nished checking
activity in the trunked system, it scans
other conventional frequencies in the
bank. (Only trunking frequencies are
programmed in trunk mode.)
If a system is inactive for 1 second and
there are no conventional channels in the
bank, the scanner starts scanning the next
selected trunk bank. If you turned DELAY
on, the scanner starts scanning the next
trunk bank after about 2 seconds.
To scan both trunking and conventional
banks, select the banks you wish to be
active with trunking off, then press TRUNK.
The scanner begins scanning. To return
to conventional scanning, press TRUNK
again.
