Basic Operation
Transmitting with the Radio or the Handset
1. Select the appropriate channel.
2. Check to ensure that the channel is clear before transmitting. The Federal
Communications Commission (FCC) and international regulations require that you not
obstruct the communications of others.
3. Press the PTT key on the microphone or the handset to transmit on the current channel.
The
TX
icon is displayed at the top of the screen.
4. Speak your message and release the PTT key.
NOTE: Five minutes is the maximum amount of time for transmission. After you have pressed
PTT key for ve minutes, PTT is disabled until you release the PTT key.
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 and hold the 25W soft key to broadcast on HI. The radio bypasses the 1 W
transmission requirement when you are pressing the 25W soft key.
Scanning and Saving Channels
IMPORTANT: If you turn on ATIS, the radio cannot scan or save channels. See page 13.
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.
