To Transmit And Receive
The radio uses the UHF-CB Channels.
For your reference a list of the available
channels and corresponding frequencies
is printed on p.27 - p.29. (Channels 22
and 23 are for telemetry and
telecommand applications, channels 61,
62 and 63 are for future use. TX is
inhibited on these channels.)
The maximum RF transmit power of
UH820SX-NB is 2W. (see Transmit Power Select, p.15.)
1. Before you transmit, listen for activity on the selected channel.
2. When the channel is clear;
- Press
(PTT)
to transmit at the selected hi/lo transmit power,
or
- Press
(BOOST)
to transmit at the maximum transmit power, regardless of
the hi/lo transmit power setting.
TX
appears on the LCD during transmit. If transmit
power is on low setting then
HI
appears when
(BOOST)
is pressed.
Hold the radio with microphone approximately
5 cm in front of your mouth with the antenna at
approximately 45° angle away from your head.
Speak in a clear, normal conversational voice.
4. When you have finished speaking, release
(PTT)
or
(BOOST)
and listen
for a response then TX disappears on the LCD.
RX
