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

covering the ID owner of each signal is half the fun of
trunk scanning!

Turning a Trunked Bank On or Off

Press during trunk scanning. The selected
DATA (ALT)
trunked banks appear. Press the bank number ( – ), to
0 9
turn the desired bank on or off.

Skipping a Trunked Bank

You can skip to the next trunked bank during scanning
by holding down for about 3 seconds.

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 talkgroup IDs.
The last four bits of a Motorola Type II talkgroup ID (a
binary 16-bit code) are the status bits. In some sys-
tems, status bits identify special situations (such as an
emergency status).
Your scanner is preset to assume that the status bits in
a talkgroup ID are set to 0 and ignores them. For exam-
ple, when the scanner receives the talkgroup ID
010111001110 0011, it reads the ID as 010111001110
0000 and converts the first 12 bits of the ID to 23776
(the talkgroup ID). However, since the status bit value
is 3 (0011 converted to decimal equals 3), the ID is ac-
tually 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 prop-
er fleet map.
Important: If you are scanning any system other than
a Motorola Type I system, be sure status bit ignore is
ON
set to or you will miss some transmissions.
