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.

Memory Mode
This mode allows recalling and operating the preprogrammed frequency or setting. This unit pro-
vides up to 200 memory channels (80 exclusive channels each for VHF and UHF, from 00 to 79CH
and 40 common channels for VHF and UHF, from 100 to 139), 1 CALL channel each for V and U
(C), 1 program-scan edge memory channel each for V and U (PL) (PH) and 1 VFO automatic

 How to program memory channel (s)
1.Select a frequency to be programmed in the
VFO mode and set the parameters as appropri-
ate. Refer to the next page for programmable
parameters.
2.By pressing FUNC key, [F] and [Memory No.]
icons will appear on the display.
3.Rotate the main dial (or press Mic UP/DOWN
key) to select the desired memory channel num-
ber.
4.An empty channel is shown with a flashing
[Memory No.] icon.
5.By pressing V/M key while [F]icon is on the
display, programming...

Channel name (Alphanumeric) registration function
The memory channels stored in the memory mode can be displayed with an alphanumeric tag
instead of the default frequency display. There are 67 characters available including A-Z, 0-9.
1.In the memory mode, select a channel to be
programmed.
2.Press the H/L key together with the FUNC key.
3.The display shows [A    ] flashing.
4.Rotate the dial to select a character to be pro-
grammed.

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...

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.

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
