Skipping A Trunked Bank; Turning The Status Bit Ignore (S-Bit) On Or Off - Radio Shack PRO-94 Owner's Manual

Skipping a Trunked Bank

You can scan conventional frequencies programmed in
the same bank by holding down
seconds. If there is no conventional frequency, the scan-
ner 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 emer-
gency status).
Your scanner is preset to assume that the status bits in a
talk group ID are set to 0 and ignores them. For exam-
ple, 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.
