PM1500 UHF remote head problem

[firebug24]

Hello all

I have a PM1500 UHF radio (remote head) that has been shutting down (power down) half way thru medical consults. The radio powers up correctly after that.

Any help is appreciated !!

Can you be a little more vague about your problem, please?

The radio is shutting off during TX . The medic has to power up the control head to finish the medical consult.
I set the TOT at 120 seconds but thinking (if this is the problem then I would increase the time more).

You need to dig a little deeper into what is going on. Take a volt meter and watch the high current feed to the radio. Also take a look at the ignition feed voltage on both the yellow and the small red wire for the control head.

the TOT set to 120 seconds should be a good setting. But do you have the alert tone set to indicate the radio has timed out?

It wouldn't take that long to do the simple testing as mentioned above. Might take 2 people to hold the mic and key the transmitter, while the other person looks at the volt meter.

Another thought that come to mind is what is the status of the engine when these radio problems are taking place? Is the vehicle running at an idle? Are all the warning lights turned on? This would make a huge difference in the way your going to do your testing. Maybe the high idle might have to be activated to prevent low vehicle voltage when on scene.

Give the boys on here something to work with to help provide you with some feedback on suggestions.
