Radio Shack PRO-94 owner manual Setting Squelch for the Trunking Mode, Storing Trunked Frequencies

Page 40

To scan both trunking and conventional banks, select the banks you wish to be active with trunking off, then press TRUNK. The scanner begins scanning. To return to conventional scanning, press TRUNK again.

SETTING SQUELCH FOR THE TRUNKING MODE

Your scanner’s squelch setting is automatically adjusted during trunking, which means it is not necessary to man- ually adjust squelch while scanning trunked transmis- sions. However, the squelch setting can affect how fast your scanner acquires the data channel, and, in some in- stances, can prevent your scanner from acquiring the data channel at all.

We recommend you set SQUELCH fully clockwise before selecting a trunked bank.

Note: Change this setting as needed for the best perfor- mance in your area.

STORING TRUNKED FREQUENCIES

Follow these steps to select, program, and store trunked frequencies.

1.Press PROG then TRUNK. TRUNK appears and one or more bank numbers flash.

2.Press the number key (1–10) of the desired target

storage bank. Select one of the trunk systems by repeatedly pressing 8 or 9 to select a trunking system type, then press E (SVC). The scanner then automatically selects the first channel in the selected bank.

Note: You can select from the following six systems:
