Notes:
• Priority WX is only for receiving a weather alert.
• When the scanner detects a 1050 Hz alert tone, priority WX activates and you receive a weather alert.
• If you program a weather frequency into the priority channel and the scanner detects a weather alert
tone on that frequency, the scanner sounds the alert tone.
To turn off the priority feature, press PRI.
Changing the Receive mode
The scanner is preset to the most common AM or FM receive mode for each frequency range. The
preset mode is correct in most cases. However, some amateur radio transmissions and trunked systems
do not operate in the preset mode. If you try to listen to a transmission when the scanner is not set to the
correct receive mode, the transmission might sound weak or distorted.
If you want to listen to trunking transmissions in closed mode, you might have to change the receive
mode.
To change the receive mode, repeatedly press MODE. The receive mode changes as follows:
AM – accesses the AM mode
FM – accesses the FM mode
CT – accesses the FM mode, CTCSS System
DC – accesses the FM mode, DCT System
MO – accesses the FM Mode, Motorola Trunking System (with a 4- or 5-digit ID code)
ED – accesses the FM Mode, EDACS Trunking System (with 4-digit decimal ID code or 5-digit AFS
code)
LT – accesses the FM mode, LTR Trunking System (with 6-digit ID code)
Note: MO (MOT), ED, and LT modes are not available when the scanner tunes up or down through the
frequency ranges in which the trunking operation is not used.
Using the Attenuator
To reduce interference or noise caused by strong signals, you can reduce the scanner’s sensitivity to
these signals.
There are two attenuator modes in your scanner. One is normal attenuator mode in which you set the
attenuator in each channel or each band/group in the search and tune mode. The other is global mode in
which you set the attenuator only once. This setting is applied all the time in every mode.
Press ATT to turn on or off the attenuator while the channel number is indicated or while the scanner is
