'■ Standard model
■ Basic model
Time-out Timer (TOT) is the function to restrict the duration for the transceiver to continuously transmit.
This function is used to prevent a user from occupying a repeater or frequency which is shared with other users.
The transceiver automatically stops transmitting and releases the channel if it continuously transmits longer than
the configured time.
Time-out Timer can be configured for each zone.
Also, timers, such as TOT Pre-alert, TOT Rekey Time, and TOT Reset Time, relevant to Time-out Timer can
be configured.
TOT Pre-alert
TOT Pre-alert is the function to notify a user that a continuous transmission is about to end by the Time-out
Timer. A TOT Pre-alert Tone (3 beeps) sounds from the transceiver before the transceiver stops the
continuous transmission by the Time-out Timer.
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.
TOT Reset Time
TOT Reset Time is the time required to initialize and reset the elapsed time for Time-out Timer.
