10.1 Initiating Voice Communications (Basic Transmission and Reception)
TOT Pre-alert
TOT Pre-alert tone is used to notify a user that a continuous transmission is about to end by the Time-out Timer. The TOT
Pre-alert Tone sounds from the transceiver before the transceiver stops the continuous transmission by the Time-out
Timer.
Example: Time-out Timer: 30 s, TOT Pre-alert: 4 s
Note
If "Off" is configured for TOT Pre-alert, no TOT Pre-alert tone will sound from the transceiver.
TOT Rekey Time
TOT Rekey Time is the amount of time from when the transceiver stops the transmission by the Time-out Timer until
transmission becomes possible again.
Example: Time-out Timer: 30 s, TOT Rekey Time: 20 s
Note
• If "Off" is configured for TOT Rekey Time, the transceiver will immediately be ready to transmit.
• The timer will be reset if the zone or channel is changed while the TOT Rekey Time is counting down.
TOT Reset Time
TOT Reset Time is the time required to initialize and reset the elapsed time for Time-out Timer.
Example 1: Time-out Timer: 30 s, TOT Reset Time: 10 s
