1750 Hz tone
To access some European repeaters, the transceiver must
transmit a 1750 Hz tone burst signal.
• This tone can be used as a ‘Call signal’ in countries out of Europe.
First, set the DTMF TX key to
“t-CALL” in the Set mode.
➥
While continuing to push
[PTT]
, push and hold
[MONI]
(BAND) for 1 or 2 sec. to transmit a 1750 Hz tone burst
signal.
■
Setting DTMF transfer speed
The DTMF transfer speed can be selected.
q
While continuing to push
[SET]
, turn the power ON to
enter the Initial set mode.
w
Rotate
[DIAL]
to select the DTMF transfer speed item,
then rotate
[VOL]
to select the transfer speed.
100 : Transfer the DTMF tones at about 100 msec. per
tone. (default)
200 : Transfer the DTMF tones at about 200 msec per
tone.
300 : Transfer the DTMF tones at about 300 msec per
tone.
500 : Transfer the DTMF tones at about 500 msec per
tone.
