Most radios have time out timers, or TOT. They are there to protect the radio, and to protect resources like repeaters and links.
A timeout timer will stop the radio from transmitting if the PTT is held down for too long. How long is too long? Well, that’s up to each operator. I use 60 seconds on most of my radios.
I recently started working with a Hytera PD782 DMR radio. This is a commercial radio and offers some extra features related to the time out timer.
The think I want to highlight here is the pre-alarm for the TOT. This is an alarm you can have go off a few seconds before the TOT cuts off your transmission. I have mine set to 5 seconds.
