Basic Operations
To transmit
1. Set the transmission band to the MAIN side.
2.
Be sure that you are authorized to operate on the
selected frequency. Check the system and monitor
the frequency to make sure that you are not going
to disturb any ongoing communications.
3.
Press the PTT key on the microphone. The TX
lamp (red) illuminates to show the unit is trans-
mitting. If the receiver’s frequency combination
is VHF amateur/accessory RX band such as Air-
band or FM broadcasting, the sub-band RX mutes
due to the nature of receiver circuit design.
4. Speak into the microphone in a normal tone
while keeping the PTT key pressed.
Hold the microphone approximately 5cm away
from your mouth. Speaking too close or
too loud
may result in poor transmitted audio.
5.
Releasing the PTT key will complete the transmis-
sion and the unit will return to the receive Mode.
NOTE: Pressing the DOWN key together with the PTT key will transmit the CALL tone
signal. DR-635E will transmit the Tone Burst signal. See page 39 for details.
The following operation is possible for sub-band while transmitting on the main
side: • Dial • V/M key • CALL key • MHz key • SQL key
IMPORTANT: If you press the PTT key in out-of-TX frequency range, the [OFF] icon
will appear on the display and no transmission will occur.
Check the frequency and/or the offset setting.
Selecting transmission power
1.
Press the H/L key. The transmission power switches
from Hi to Mid, Mid to Lo and then Lo to Hi.
At MID power, the [Mi] icon, and at LOW power,
the [Lo] icon illuminates. Nothing appears on the
display at Hi power. The default is HI power.
The RF meter shows
••
when transmitting at LOW
power,
••••
at MID power and
••••••
at HI power.
IMPORTANT: While operating with High-power output setting, when the internal tem-
perature exceeds certain level, a protection circuit turns the TX power
automatically to MID setting (it resumes high setting automatically when
cool down).
