a weather alert tone in Priority WX mode, Priority Channel! appears for 3 seconds then changes to

• When the scanner detects a 1050 Hz alert tone, priority WX activates and you receive a weather
alert.

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, DCS System
MO – accesses the FM Mode, Motorola Trunking System (with 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)
