TX630
transmitting
To transmit, press and hold the Push-To-Talk
(PTT) switch. The other radio you are talking
to must be set to the same channel (and
CTCSS code if applicable). Hold the TX630
approximately 5 to 8 cms from your face
with the antenna vertical and speak into the
built-in microphone.
While the PTT switch is pressed, the LED
indicator on the upper edge of the radio
will light RED and the icon will appear
on the LCD.
When you have finished speaking, release
the PTT switch to receive incoming signals
(it is not possible to transmit and receive
at the same time). If no further signals are
received, the unit will to revert to
standby mode.
tiP:
The PTT switch can also be used to
transmit a Call Alarm melody. When the Call
Alarm melody is enabled (see Mode settings
for more details on the Call Alarm settings),
pressing the PTT switch twice quickly will call
another party on the same channel and play
the Call Alarm melody in their radio’s speaker.
When this happens, the icon will appear
and the LED indicator will light RED for about
5 seconds.

DUP Button
Duplex operation allows the TX630 to
transmit on a different frequency to that
which it receives. This allows operation
through repeater stations in your area.
Repeaters automatically re-transmit your
signal over a much wider area, providing
greatly increased range. The Duplex mode
only works on channels 1 - 8. With Duplex
selected, your TX630 actually transmits 30
channels higher than it receives.
To switch between Simplex and Duplex
modes, select a duplex channel (1-8) then
briefly press the
DUP
button. When Duplex
mode is selected, ‘DUP’ appears on the
display on that channel.
