* and # Digit Time is the function to extend the transmission time for the * tone and # tone of when
the DTMF code is sent out.
Since * tone and # tone are more frequently used for special tasks than 0 to 9 tones, this function is
used for the receiving transceiver to easily recognize the incoming DTMF code.
The length of time to transmit the * tone and # tone is the sum of the transmission time configured in DTMF
Speed and the * and # Digit Time.
Transmission time for the * tone and # tone of DTMF = value configured in DTMF Speed
(Digit Time) + value configured in * and # Digit Time
Example: * and # Digit Time: 100 ms, Encode Code: *01
-
If the first digit of the DTMF code is the * tone or # tone, the transceiver compares the extension time
configured in First Digit Time with the extension time configured in * and # Digit Time, and uses the longer
extension time to send the first digit.

D Code Assignment is the function to select whether the D Code is used for the D tone of DTMF or a dialing
pause (unmodulated transmission).

2-tone signaling uses a pair of 2 different tone frequencies in series for an individual call.
2-tone is a signaling system that can receive a signal with squelch disabled only when 2 tone signals in series
sent from the transmitting transceiver match the tone signals preconfigured for the receiving transceiver.
2-tone consists of 2 tone signals in series with 2 different frequencies within the frequency range between 288.5
Hz and 3106.0 Hz. These 2 tone signals are sent in series with the carrier wave.
