DTMF Tones
DTMF
DTMF tones can be transmitted directly by pressing the
numeric keypad, or the DTMF Button can be used in
conjunction with the numeric keypad to create a DTMF
sequence of up to 3-digits. A DTMF sequence entered
using the DTMF button is stored and displayed, and can
then be transmitted by simply pressing the DISP
dispatch button. DTMF tones are heard on the front-
panel speaker whenever they are being transmitted.
DTMF Disable prevents use of the
DTMF button to create a DTMF
sequence, but does not prevent
sending DTMF directly using the
numeric keypad.
* Disable or # Disable prevents DTMF
characters * or # from being sent
directly whenever the numeric
keypad is pressed.
Keypad Disable prevents DTMF from
being sent directly whenever the
numeric keypad is pressed, but still
allows you to create a DTMF
sequence using the DTMF button.
