19 Function Reference (FUNC) Version: 1.01 USA7 TOT (TIME OUT TIMER)This function limits the continuous transmission time(TOT). Therefore, this function is used to prevent acertain user from occupying a channel for long time whensharing the same channel with other parties.The transmission automatically terminates when TKR-750/850/751/851 continues to transmit for more than theconfigured time and returns to the reception mode. TheWarning Alert Tone (Refer to 9 Tone.) beeps until the PTTsignal input is disabled.You can configure this function to the Repeater PTT, theExternal PTT, and the Local Mic PTT.Note: The TOT of the Repeater PTT/External PTT is different fromthe PTT of the Local Mic PTT.
