Description
DTMF Speed
is the speed to send out the DTMF codes. Transmission speed of the DTMF code can be
configured by entering the number of digits to be sent per second. The transceiver sends the DTMF code at the
configured speed.
The number of digits of the DTMF code to be sent per second can be selected from 6, 8, 10, or 15 by using
KPG-D6/ D6N.
The following are durations for Digit Time (transmission duration) and Gap Time (silent duration) depending on
the selected value.

Description
First Digit Time
is the function to extend the length of time to send the first digit of the DTMF code when the
transceiver starts sending the DTMF code.
Extending the transmission time of the first digit of the DTMF code helps the receiving transceiver easily
recognize the incoming DTMF code in order to avoid failure in receiving the DTMF code while the transceiver is
in the battery saver mode or scanning.
The length of time to send the first digit of the DTMF code is the sum of the transmission time configured in
DTMF Speed and the
First Digit Time
.
Transmission time for the 1st digit of DTMF = value configured in DTMF Speed (Digit Time) + value
configured in First Digit Time
Example: First Digit Time: 100 ms, Encode Code: 123

Description
First Digit Delay Time
is the length of time from when the transceiver starts transmitting until the transceiver
starts sending the first digit of the DTMF code.
The transceiver transmits an unmodulated signal until the length of time configured in
First Digit Delay Time
elapses.
