along with BANK and TRUNK .
2. Use the number keys to enter the number for the
trunked bank you want to scan, then press SRC .

the scanner finds it, it begins trunk tracking.
If you entered all of the trunk’s frequencies, you
should be able to follow conversations between
broadcasters even when they change frequen-
cies. IDs, which represent different service
groups, appear.
3. To return to conventional scanning, press TRUNK
again.
