Basic Operations
Shift Direction and Offset frequency setting
Conventional repeaters are operated in the DUPLEX mode, which receives an incoming
signal on one frequency and re-transmits on another. The difference between these two fre-
quencies is called the offset frequency. The offset is variable between 0 to 99.995MHz on
this unit.

1.After pressing the FUNC key, and pressing the
MHz key while [F] appears on the display, the
display will show the current status of the off-
set frequency and the shift direction. By repeat-
edly pressing the MHz key, shift direction will
be changed as shown to the right.
2.By rotating the dial (or by pressing the UP/
DOWN key) while the shift frequency is dis-
played, one click will change the frequency by
one channel step.
3.After pressing the FUNC key, rotating the dial
will change the frequency by 1MHz depend-
ing on which direction the dial is rotated (or if
the Mic UP/DOWN key is pressed).

Basic Operations
CALL mode
This is a memory mode that allows the transceiver to quickly recall the assigned memory channel
by simply pressing the CALL key, regardless of the current status of the unit.
The default setting is 145.00MHz/433.00MHz, and one CALL channel is available on each band.
To recall a CALL channel
Select the desired VHF or UHF band by pressing the BAND key.
1.Press the CALL key. The C icon appears on the
display and the transceiver enters the CALL
mode. In this mode, the main dial or the Mic
UP/DOWN keys cannot change the frequency
or memory channels.
2.Press CALL key again or press V/M key to exit
CALL mode.
3.No scan functions are available in the CALL
mode.
To store a desired setting in the CALL channel, follow the memory mode programming instruc-
tions and assign your selected settings to memory channel C. The call channel can be modif ied but
cannot be eliminated or hidden.
To receive signals
1.Be sure to have the unit connected to the ap-
propriate antenna, powered on, set the audio
volume and squelch level properly on both the
MAIN and SUB bands.
2.Select the desired band by pressing the BAND
key and browse frequencies or select desired
frequency to listen to ongoing communications.
The S-meter shows relative signal strength
when the transceiver detects an incoming sig-
nal, and the RX display lamp (green) turns on.
3.If the S-meter indicates an incoming signal but
nothing is heard from the speaker, check the
audio level, squelch level, and CTCSS/DCS de-
coding status, which are explained elsewhere
in this manual.

Basic Operations
IMPORTANT: The Monitor function only operates on the MAIN band. The Monitor func-
tion operates irrespective of Tone squelch/DCS function setting.
Reverse function
This function is for monitoring the transmission frequency
instead of receiving frequency in repeater operation. This tech-
nique is commonly used to check if it is possible to commu-
nicate without using a repeater by monitoring the accessing
station’s signal strength.
When -5.000MHz SHIFT is set
1.Keep pressing the SQL key for more than 1 sec-
ond while SHIFT is set.
[R] icon illuminates on the display to indicate
that the reverse function is activated and the

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 transmitting. The SUB-
band audio mutes during the transmission. If the receiver’s
frequency combination is VHF amateur/accessory RX
band such as Air-band or FM broadcasting, the transmission
becomes prohibted due to the nature of receiver circuit
design. To be able to transmit, please exit from the
accessory RX frequency on the SUB-band side, and
replace the SUB-band frequency with one of other bands.
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-620E will transmit the Tone Burst signal. See page 39 for details.
IMPORTANT: If you press the PTT key while out of the transmission frequency range,
the [OFF] icon will appear on the display and no transmission will occur.
