17 DTMF
The TKR-750/850/751/851 supports DTMF (Dual Tone
Multiple Frequency) Signalling.
The DTMF signalling uses two different frequency tones
simultaneously. DTMF is used to remotely control TKR-
750/850/751/851.
(Refer to 18 Remote Control.)
DTMF signalling uses two different frequencies (high
frequency and low frequency) and consists of (0) - (9),
(A) - (D), (*) and (#) tone.

17.2 First Digit Delay Time
The First Digit Delay Time is a delay time between the
time that the TKR-750/850/751/851 begins to transmit
and the time that it starts to send DTMF code.

" Configuring the First Digit Delay Time (Refer to
FPRG 6.7.2 First Digit Delay Time.)
17.3 First Digit Time
The First Digit Time is a extension time to transmit a first
digit of the DTMF code.
(Refer to 17.6 Decode, 17.7
Frequency.)
The transmitting time of the first digit is obtained by
adding the DTMF Speed to the First Digit Time.

and # Tone of DTMF code.
The transmitting time of * tone and # tone is obtained by

to 17.1 DTMF Speed.)
When the first digit of the DTMF code is "*" tone or "#"
tone, TKR-750/850/751/851 compares the extension time
to transmit the first digit configured in the First Digit Time
with the * and # Digit Time and uses the longer extension
time to transmit.

17.5 Encode
Encode is a DTMF code to be transmitted when the
command is entered from the external device or the
function assigned to an auxiliary port activates/
deactivates.
