Timeout Timers on Hytera DMR Radios

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.

Take a look at the video for more details.
