SETTING SQUELCH FOR THE

TRUNK TRACKING MODE

Your scanner’s squelch setting is automatically adjust-

ed during trunk tracking, which means it is not neces-

sary to manually adjust squelch while tracking trunked

transmissions. However, the squelch setting can affect

how fast your scanner acquires the data channel, and,

in some instances, can prevent your scanner from ac-

quiring 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 pro-

vide better performance in your area.

STORING TRUNKED

FREQUENCIES

Before you set up your scanner to track a trunked sys-

tem, 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. Although you can store frequencies for more

than one trunked system in one of your scanner’s

banks, the scanner only scans the frequencies

associated with the first data channel it finds.
