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 commu-
nications.
3.
Press the PTT key on the microphone.
TX display lamp (red) illuminates to show the
unit is transmitting.
4.
Speak into the microphone in a normal tone
while keeping the PTT key pressed.
Hold the microphone approximately 5cm away
from your mouth. Keeping this distance too
close or speaking too loud may result in poor
audio.
5.
Releasing the PTT key will complete the trans-
mission and the unit will be back for receiving.
NOTE:
Pressing the DOWN key together with the PTT key will transmit the CALL tone
signal. DR-620E will transmit the Tone Burst signal. See page 39 for details.
IMPORTANT: If you press the PTT key out of the transmission frequency range, [OFF]
icon will appear on the display. Transmission is not possible in this while.
