DTMF

DTMF means Dual Tone Multi Frequency and is
used when the radio is required to operate in a
radio system with an interface to public or private
telephone systems (PSTN or PABX).
To enter the DTMF mode, press DTMF function
button (13e), the General Display will show the
DTMF icon . Your radio may be programmed to
automatically send an access code which connects
you to the telephone system. You will hear the
access code, after which you will hear the dialling
tone. Dial the required number directly from the
keypad.
If your system does not have an automatic access
code, on entering the DTMF mode dial the required
number directly from the keypad.
When the number is completed a ringing or busy
tone is heard and the conversation is handled as
described in "Communication Procedure".
To disconnect from the telephone system, either
press the DTMF button or manually dial a specified
disconnect number, depending on your system
configuration.
To exit the DTMF mode, press the Clear button for
longer than 2 seconds.
