SETTING THE SCANNER TO THE TRUNK TRACKING MODE

Press TRUNK to switch between the scanner’s conventional and trunk tracking modes.

SETTING SQUELCH FOR THE TRUNK TRACKING MODE

Your scanner’s squelch setting is au- tomatically adjusted in the trunking mode, which means you do not need to manually adjust squelch while tracking trunked transmissions. How- ever, the squelch setting can affect how fast your scanner acquires the data channel, and, in some instances, can prevent your scanner from acquir- ing the data channel at all.

We recommend you set SQUELCH to this position before selecting a trunked bank.

Note: You can change this setting, if necessary, to provide better perfor- mance in your area.

PROGRAMMING

TRUNKED

FREQUENCIES

Before you program your scanner to track a trunked system, consider the following:

Valid trunked system frequencies range from 851.0000–868.9875 in 12.5 kHz steps.

You can use any of your scanner’s banks as either a trunk tracking bank or conventional scanning bank, but you cannot mix the two.

The scanner only scans one trunked system at a time. Al- though you can store frequencies for more than one trunked system in one of your scanner’s banks, the scanner only scans the fre- quencies associated with the first data channel it finds.

Before scanning a trunked system’s transmissions, you must store the trunked system’s frequencies in one of the banks in your scanner by following these steps.

1.Hold down TRUNK until the scanner beeps twice. BANK, TRUNK, and the bank numbers flash.
