DTMF side tone When the DTMF code word is been sent, the speaker issues the
corresponding DTMF tones.
PTT ID select ‘None’, ‘Pre Only’, ‘Post Only’ or ‘Pre & Post’.
Group Code You can use the DTMF characters ‘A’, ‘B’, ‘C’, ‘D’, ‘*’ or ‘#’ to set up
a group called ‘universal character code’. If the receiver receives a
valid ID code and one or all of its digits are replaced by the
‘universal character’ group call code, the call will become decoded.
KeyUp Encode The analog channel transmits the PTTID corresponding to the DTMF
code, as the channel is been activated by pressing the PTT.
KeyDown Encode The analog channel transmits the PTTID corresponding to the DTMF
code, as the channel is been deactivated by releasing the PTT.
Auto Reset Time When the signal is decoded correctly, the automatic reset timer
resets the DTMF decoder and mutes the speaker if there is no
communication activity within a certain period of time. You do not
need to perform a manual reset (using the monitor key). The timer
starts running as the carrier drops.
First Digit Time Allows you to set the delay time from the start of transmission to
the first DTMF digit (factor that takes the decoder start time into
account). Increasing this time interval is the same as adding ‘First
Code Duration’.
Digit Duration Allows you to set the delay time from the start of the launch to the
first DTMF digital transmission (considering the factors that start
the decoder's time). Increasing this interval is the same as
increasing the duration of the first code.
*# Digit Time [ms] This parameter is extending the # * sound transmission time. In
some systems, these two codes must be set longer than the
numerical codes.
