voice channel or during trunking delay
time. Therefore the priority check seems
random during peak hours. Do not over-
estimate the priority check during trunk-
ing operation.

• If you program a weather channel as the

priority channel, the scanner stays in the
priority channel only when the scanner
detects the weather alert tone.

To program a frequency in the priority chan-
nel:

1. Press 

MAN

.

2. Use the number keys to enter the chan-

nel number which contains the fre-
quency you want to program as the
priority channel. Then press 

MAN

 again.

3. Enter the desired frequency, then press

ENTER

.

Note: This scanner cannot set a channel as
the priority channel if the channel's receive
mode is MOT or ED.

To program a weather channel as the priority
channel:

1. Press

 and the scanner sounds an

alert. The scanner sounds the alert for five
minutes when it receives the weather alert
signal. After five minutes the alert stops and
the scanner beeps every ten seconds. Press
any key to stop the sound. The scanner is
ready to receive a new signal.

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.
