DTMF Speed

This is a speed to send DTMF code.
Select the speed from the dropdown list.
Range 6, 8, 10, 15 digit/s
Default 6 digit/s
6.7.2

First Digit Delay Time

This is a delay time between the time when TKR-750/850/
751/851 starts transmitting and the time when it sends the
DTMF code.
Configure the duration by the spin buttons or directly
enter the value to configure the duration.
Range 100 - 1000 ms
In steps of 50 ms
Default 100 ms
6.7.3

First Digit Time

This is a duration time to transmit the first digit of the
DTMF code. Select the duration from the dropdown list.
This function ensures the recognition of the first digit of
the DTMF code detection for the receiving transceiver
using the Power Saver or Scan functions.
The duration of the first digit of the DTMF is obtained by
adding the transmission time configured in the DTMF
Speed and the First Digit Time.

* and # Digit Time

This is a duration time to transmit the "*" tone and the "#"
tone of the DTMF code. Select the delay time from the
dropdown list.
In some case, these tone is used for special function,
such as Connecting tone and Disconnecting tone. To
extend these tone transmitting time, it allows to receive
them correctly.
The time of the "*" tone and the "#" tone is obtained by
adding the transmission time configuring the DTMF
Speed to the "*" and "#" Digit Time.

Range 0, 100, 500, 1000 ms
Default 0 ms
Note: When the first digit of the DTMF code is "*" tone or "#" tone,
TKR-750/850/751/851 compares the duration time to
transmit the first digit configured in the First Digit Time with
the "*"and "# "Digit Time and uses the longer delay time to
transmit. (Refer to 6.7.3 First Digit Time.)
