Hytera TC-518 [17/25] Battery strength indicator

Time-out Timer (TOT)

Limits the amount of time the radio user can continuously transmit on a channel. If the

user holds down the PTT longer than the preprogrammed time period, the radio will

automatically stop transmitting and generate a warning tone. To stop the warning tone,

release the PTT.

Your dealer may program the alert tone that sounds before the TOT timer nearly expires.
