We recommend you set SQUELCH to the position shown here before select- ing a trunked bank.

Note: Change this setting as neces- sary to get the best performance in your area.

PROGRAMMING

TRUNKED

FREQUENCIES

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

•Valid trunked system frequencies are as shown below.

Motorola system: 935.0125–939.9875 MHz (in 12.5 kHz steps) 851.0000–868.9875 MHz (in 12.5 kHz steps) 406.0000–512.0000 MHz (in 12.5 kHz steps) 137.0000–174.0000 MHz (in 5 kHz steps)

Ericsson EDACS system: 900.0000–956.000 MHz (in 12.5 kHz steps)

806.0000–899.9875 MHz (in 12.5 kHz steps, except cellular frequencies)

406.0000–512.0000 MHz (in 12.5 kHz steps) 137.0000–174.0000 MHz (in 5 kHz steps)

•You can use any of your scanner’s banks as either a trunk scanning 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.Set the scanner for conventional scanning, then hold down TRUNK until the scanner beeps twice. BANK, TRUNK, and the bank numbers flash.

2.Press a number key to select the bank for the trunked system’s fre- quencies. To select a bank between 11 and 20, press SHIFT then the number keys. The scan- ner displays one of six system types.

3.Use ▲ or ▼ to select the system type, then press E.
