Basic Operation
Bypassing the LO (1 W) Transmission Power Setting
In the USA frequency band, transmissions on Channels 13 and 67 are required to be low-
power (1 watt) by default. You can bypass this power setting by pressing the 25W soft key
during transmission.
1. If you are on USA Channels 13 or 67, when you press the PTT key, the screen displays
a message to press 25W to bypass the 1 W transmission requirement.
2. Press the 25W soft key to broadcast on HI. The radio bypasses the 1 W transmission
requirement until you release the PTT key.
Scanning and Saving Channels
IMPORTANT: If you turn on ATIS, the radio cannot scan or save channels. See page 12.
Scanning All Channels
When you scan channels, the radio searches for channels that are broadcasting. If a channel
is broadcasting, the radio pauses on that channel until the broadcast stops. After four
seconds of inactivity on the channel, the radio resumes scanning.
1. Select SCAN > ALL.
2. Choose from the following options:
SKIP—this option is displayed if active channels are detected. When you select
this option, the system resumes the scan and does not include that channel in
subsequent passes.
+CH16—Channel 16 is scanned every other channel (for example: 21, 16, 22, 16,
and so on). “ALL SCAN +CH16” is displayed on the screen.
-CH16—Channel 16 is scanned in its normal order (for example, 14, 15, 16, 17, and
so on). “ALL SCAN” is displayed on the screen.
EXIT—returns you to Home screen. The system ends the current scan and continues
to receive on the channel where you ended the scan.
Saving Channels
You can save any channel other than the WX (weather) channels to the transceiver memory.
You can scan your saved channels separately from scanning all of the channels that radio
receives. There is no limit to the number of channels you can save.
To save a channel:
1. Select SCAN.
2. Turn the Channel knob to access different channels.
3. To save a channel, select SAV CH. A star on the top of the screen denotes a saved
channel.
