SCANNING A TRUNKED BANK

You can scan one trunked bank at a time. Once you have stored frequen- cies for a trunked system in one or more of the 20 available banks, and you are scanning non-trunked fre- quencies, follow these steps to begin trunk scanning.

1.Turn on the scanner and begin scanning in conventional mode.

2.Press TRUNK. The indicators for all banks that have been pro- grammed with trunked frequen- cies flash, and TRUNK and BANK appear.

4.Use the number keys to activate the trunked bank you want to

scan. appears under the selected bank’s number.

5.Press SEARCH. As the scanner searches for the trunk’s data channel (the channel that con- trols the trunk), SEARCH flashes. When the scanner finds the data channel, it begins trunk scanning.

If you entered all of the trunk’s fre- quencies, you should be able to follow conversations between broadcasters even when they change frequencies. IDs which represent different service groups appear.

Note: To see the bank currently in use (for about 5 seconds), press
