The transceiver has 3 methods of transmitting a DTMF code
sequence. Select a desired option in the Set mode.

• kEy
: Transmits the appropriate DTMF code assigned to the
pushed key. (default)
• mEm
:
Transmits the programmed DTMF code sequence in the
DTMF memory channel assigned to the pushed key.
• t-CALL : No DTMF code can be transmitted. However, while
continuing to push
[PTT]
, pushing
[MONI]
(BAND)
transmits a 1750 Hz tone burst signal.
r
Push

to return to the frequency display.
D
Manual DTMF code transmission
First, set the DTMF TX key to
“kEy” in the Set mode.
➥
While continuing to push
[PTT]
, push the desired keys to
transmit a DTMF code sequence manually.
