Hint:
While searching, you may not know exactly to whom the talk group IDs are assigned until you listen
awhile. To locate talk group ID lists for your local police, fire, and other agencies, refer to frequency guides
available at your local RadioShack store or on internet sites such as www.trunkscanner.com. You can also
determine the type of agency you are listening to after a short while, be it a police, fire, or emergency medical
2-way radio user. Once you have identified the type of service, note the associated talk group ID of that unit
for future programming. See “Identifying a Trunked Frequency” on Page XX. Determining the service
associated with a talk group ID might take awhile, but discovering the ID owner of each signal is half the fun of
trunk scanning!

Turning a Trunked Bank On or Off
Press and hold
SCAN/MAUNAL
during trunk scanning. The selected trunked banks appear.
Press the bank number (
0
–
9
), to urn the desired bank on or off.
Skipping a Trunked Bank
You can scan conventional frequencies programmed in the same bank by holding down
about 1 second. If there is no conventional frequency, the scanner
scans the next bank.
Turning the Status Bit Ignore (S-Bit) On or Off
You can set how your scanner works with status bits (also called S-Bits),
letting you control how the scanner interprets and displays talk group IDs.
The last four bits of a Motorola Type II talk group ID (a binary 16-bit code) are the status bits.
In some systems, status bits identify special situations (such as an emergency status).
Your scanner is preset to assume that the status bits in a talk group ID are set to 0
and ignores them. For example, when the scanner receives the talk group ID
010111001110 0011, it reads the ID as 010111001110 0000 and converts the first 12 bits
of the ID to 23776 (the talk group ID). However, since the status bit value is 3
(0011 converted to decimal equals 3), the ID is actually 23779.
If you are scanning a Motorola Type I system and do not have a fleet map for that system,
you might have to turn off status bit ignore in order to determine the proper fleet map.
Important:
If you are scanning any system other than a Motorola Type I system,
be sure status bit ignore is set to
ON
or you will miss some transmissions.
Follow these steps to turn status bit ignore on or off.
1. If you are not in conventional programming mode, press
E/PGM
beforehand. Press

Identifying a Trunked Frequency
While ID scanning (looking for IDs within a trunked system) or performing an ID search,
press
to see the current trunked frequency. (The frequency flashes twice.) Then hold down
