DTMF
DTMF stands for Dual-Tone Multi-Frequency. Basically DTMF is an advanced
signaling method that uses dual sinusoidal signals for any given code. A good example
of DTMF in use is a touch tone telephone system. In two-way radio systems, DTMF
is mainly used for automation systems and for remote control. For example, DTMF
can be used to remotely activate repeaters by transmitting a specific sequence of
numbers.

The Baofeng BF-F9V2+ allows for full implementation of DTMF. The numerical and
the [SCAN] and [LOCK] buttons correspond to the matching DTMF tones. The
numeric buttons correspond to the same DTMF tones, but to access the A, B, C, &
D codes, the [MENU], [UP], [DOWN], and [EXIT] buttons are used, respectively.
To send DTMF codes, press the buttons corresponding to the message you want to
send while holding down the [PTT] button. See below for the mapping of DTMF
tones to the keypad.
