the scanner beeps every ten seconds. Press
any key to stop the sound. The scanner is

Notes:
• Priority WX is only for receiving a
weather alert.
• When the scanner detects a 1050 Hz
alert tone, priority WX activates and you
hear a weather alert.
• If you program a weather frequency into
the priority channel and the scanner
detects a weather alert tone on that fre-
quency, 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 trans-
missions and trunked systems do not oper-
ate 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.
