TRANSMIT DELAY

For each of the four interface channels, a knob is provided on the front panel to
set the amount of time that audio will be delayed before it is transmitted. The
Transmit Delay is adjustable as follows:

Table 1: Transmit Delay Switch Positions

In many trunking radio systems, the delay from keying a transmitter to having a
voice channel ready for use may be variable. The Automatic Transmit Delay
setting is useful in this situation to provide the minimum delay necessary for a
complete voice transmission. When set to automatically delay the transmitted
voice, the TW-60 listens for the tones the two way radio is producing and delays
the transmission of the voice until the tones stop.
