Radio Shack PRO-94 Skipping a Trunked Bank, Turning the Status Bit Ignore S-Bit On or Off

Skipping a Trunked Bank

You can scan conventional frequencies programmed in the same bank by holding down SRC (LIMIT) for about 2 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.

1.Hold down SCAN until the current status bit ignore setting (ON or OFF) appears.

2.Press 8 to select ON or 9 to select OFF, then press E (SVC).
