I don’t know if the lockup behavior is ESD related or not. I’ve had the lockup behavior happen a couple of times on each of my DTR700 radios in my DTR700 fleet. In one case I had to pull the battery from the radio to reset it. That was before I learned that it will eventually reboot itself if you keep pressing PTT or the power button multiple times after it has lost its mind. The behavior is also independent of operating mode so it doesn’t matter whether it’s operating in a public or private group or Profile ID mode group. The behavior is random like you said.
I learned in another forum that in order to get problem reports and feature requests communicated to the right people inside Motorola, you need to contact your Motorola dealer and have them forward the information along. Motorola will do nothing and not respond if you try to contact them directly. All requests for new features and/or problem reports have to be communicated through a Motorola dealer. I don’t like it but that’s how Motorola chooses to do business.
I recommend contacting your Motorola dealer and report/complain about the DTR600/700 strange lockup behavior and ask that the information be forwarded to Motorola. You are not alone. Hopefully Motorola will address it. Also request that Motorola add automatic gain control (AGC) to the DLR transmit audio like they did in the DTR600/700 models. The DTR600/700 has the best audio thanks to AGC in the Tx audio. The DLRs have the worst audio. The legacy DTR410/550/650 models fall somewhere in between.
I reported the DTR600/700 lockup behavior to my Motorola dealer. I also sent them a feature request to add AGC to the DLR transmit audio to help clean them up.
