Beyond the Basics

To scan a mix of trunking and conventional banks, select the banks you wish to be active, and then press TRUNK. The scanner will instantly begin scanning. You can switch to search mode and the scanner will search for any active IDs on the system.

Note	To switch ID scan or ID search, press SRCH in the trunked
	system.

about multi-track

When more than one trunk system is active (for example two or more trunked systems or a trunked system and one or more conventional frequencies), the scanner jumps between systems/frequencies as follows:

TRUNK SCAN: The scanner moves to a trunked system and looks for IDs in your scan list(s) for up to 1 second. If it ﬁnds no activity on your programmed talk groups, it moves on to conventional channels in the same bank or to the next active bank. If the scanner ﬁnds a talk group in one of your active scan lists, you will begin to hear that communication and the scanner will display the proper talk group number. When the communication ends, the scanner will wait for 2 seconds for any further replies and, if none, the scanner will move to the conventional channels in the same bank or to the next bank.

The scanner will not look for any other IDs within the same trunked system (as this would slow the scan process). If you press the e key while you are listening to one ID, the scanner will check to see if another ID in your scan list is active. It will disregard the ID which you were just monitoring.

TRUNK SEARCH: This mode works similarly to trunk scan. If the scanner ﬁnds any (nonlocked-out) ID when it checks the control channel, you will hear it. You will then hear any replies that follow within 2 seconds. After that, the scanner moves on and does not continuously search the system for additional IDs (on busy systems you would never leave the
