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.
