As I said it did clean up ok, gonna do some more, this week.
Just was odd, it has never occured in the many many many years that I've had them. Maybe the heat and humidity this past month.

Motorola has released another firmware update for the DTR 600/700/720 models. The DTR720 is not sold in the USA and I assume it is the Latin America version.
The CPS was also updated to include the new features. The latest CPS rev is R07.02.

DTR700 Digital Two Way Radio - Motorola Solutions
DTR series radios are now more reliable than ever - enabling interference free, private communications to help your team stay focused while keeping communications private. With its slim and rugged design the DTR700 digital two-way radio is IP54 rated and operates at 900 MHz.www.motorolasolutions.com
I found this while browsing Motorola's site for new stuff.

There is no mention of any fixes for the strange lockup behavior I have encountered a few times.
Looks like I will be doing another update to the firmware in my DTR700 fleet tonight.![]()
I successfully updated the firmware in my DTR700 fleet. I played around with the Manager Mode features. Remote Monitor, Remote Disable, and Remote Enable all work as advertised. I found the Manager Mode features in the DTR700 also works with the legacy DTR410/550/650 models. I tested the DTR700 Manager Mode features with one of my DTR650 radios. I was able to remotely monitor and remotely disable and enable the DTR650 from my DTR700, and vice versa. The DTR700 Manager Mode features appear to be backward compatible with the legacy DTRs.
Now for the BAD news. One of my DTR700 radios exhibited the occasional strange lockup behavior that I posted about earlier. The firmware update did not fix this behavior. I was out and about with the wife today and we were using a pair of DTR700 radios and mine locked up and played dead for a few minutes. The radio appears to be brain dead except for the display which appears normal. There is no response from the keypad or PTT or any buttons and no transmit or receive. It does send an acknowledgement to another radio talking to it to allow the other radio to continue transmitting but nothing is heard out of the dead DTR700. Pressing and holding PTT several times over about a minute eventually caused the radio to reset and reboot itself and then everything was OK after that.
The lockup happened after I got out of my car and right when I pulled the radio out of my coat pocket. We tested the radios only a minute or so earlier and everything was OK before getting out of the car. It was windy and cold and dry today. Very low relative humidity. I'm thinking the radio took a zap of electrostatic discharge (ESD) when I pulled the radio out of my coat pocket. If it actually is an ESD problem, i.e., has poor immunity to ESD, this is a hardware issue and something that might not be fixable with a firmware update.
One of my DTR700 locked up yesterday just as you described. I too have the latest firmware. I ended up pulling the battery to reset it.
Pressing and holding the power button several times for several seconds at a time or pressing and holding PTT multiple times will eventually cause the radio to reset. A software watchdog timer probably expires and forces a reset. The behavior appears to be due to a software crash. It does not appear to be ESD related like I thought earlier.
You should complain to your Motorola dealer and request that they forward your complaint to Motorola. This is the ONLY way to get Motorola to respond to their customers. Motorola will not respond at all if you try to contact them directly. All reports of problems or requests for enhancements have to come through their dealers. I don't like it but that's how Motorola chooses to do business.
I forwarded my report(s) of the lockup behavior to my Motorola dealer who then forwarded it to Motorola. Hopefully Motorola will debug this and fix it with a FW update. The lockup behavior was there with the earlier firmware. It may have been there from day one but I didn't notice it right away.
Any replies from Motorola or the dealer? I am interested to know the answer.

But that quirk makes it an unreliable radio. Mother M should address it. It's not like these radios are CCRs. It's a niche radio system to begin with and this is something major that would keep people from purchasing them.![]()
I agree 100%. Motorola needs to address the lockup behavior. The best we can do is complain to our Motorola dealers about it so Motorola hears about it and decides to dedicate some engineering resources to it.
Currently running a fleet of about 35 DTR-700s, latest firmware loaded. None have exhibited this lockup behavior after about a month of use. This is my first time hearing about such a problem. Will definetly pay more attention and report back with any findings.

After experiencing a few more random lockups with my DTR700s and having to pull the battery once, I did a little experimenting. The random lockup behavior appears to be due to a software crash of some sort. I tried disabling the battery save feature in the CPS to see if that makes any difference. I have had the battery save features in other radios sometimes cause little quirks in the radio's operation.
The help file in the CPS warns that disabling the battery save function will shorten battery life on a charge by about 20%. So far after a week of playing around with my DTR700 radios with the battery save function disabled, no more lockups have occurred. The battery life on a charge is still acceptable. Time will tell if I experience anymore lockup behavior or not.
I have been running my DTR700 fleet for a while with the battery saver disabled to help debug and understand the lockup behavior. My DTR700 fleet is among the first batch of them built in December 2018 and has the lockup behavior. The behavior is tough to repeat but happens on every one of them.I had an interesting conversation today with Ken at North Georgia Communications about the LEX L11 Mission Critical LTE device in the other thread and we got to talking about the DTRs and DTR700 in particular. I mentioned the lockup behavior I've run into and he said Motorola is aware of the issue and has been working on it. Ken mentioned that the issue has been fixed in later built DTR700s. I don't have any details or range of build dates affected. I assume the DTR600 has the same issue.Motorola MOTOTRBO (TM) Products, Sales and Solutions

My DTR700 fleet is among the first batch of DTR700 in the USA and they have a December 2018 build date. FL2WAYRF may have a more recent build of 35 DTR700 radios that already have Motorola's fix in place.
My DTR700 fleet seems to be working better with the battery save feature disabled. (The default in the CPS is ON) Time will tell if I encounter any more lockups.
The one downside IMO is inability (at least per the manual) to operate the radios on RX while in the charger.
Not sure how true that is anymore. We have a fleet of DTR700's. I use mine all day, place it in the charger (still on) and it charges overnight. Pick it up in the morning and keep going, rarely ever reboot it. It was sitting in my charger for the last 4 months (on and receiving) and I pick it up in the morning and still works like a charm. Haven't had any battery issues. Probably not "ideal" or "recommended" but just my real-world experience, haven't seen any issues.You shouldn't be doing that anyway. That's a great way to destroy the batteries.

I am happy to report NO more random lockups have occurred after disabling the battery saver with the CPS. I have given my DTR700s some heavy use when my wife and I are out shopping to try get lockups to occur. My wife is not a ham but she absolutely LOVES using these radios when we are out shopping or doing whatever. She specifically DOES NOT want to use FRS bubble pack radios instead of the DTRs because the DTRs simply work so much better. (LOL) She is not a ham but fully "gets it" when it comes to using high quality radios to stay in touch during our day to day activities.
Disabling the battery saver in the CPS appears to be effective as a workaround. Battery life on a charge is about 20% shorter as Motorola warns in the Help file in the CPS. The slightly shorter battery life on a charge has not been a problem, even with heavy duty use throughout the day. The battery saver only affects the standby time.
My gut says there was a hardware issue in the early DTR600/700s that created the random lockup behavior, something that can't be fixed in firmware. All of my DTR700s have the latest FW after I updated them a while back and still had the lockup behavior. I suspect the issue was addressed by a chip change, i.e., through a revision of Silicon in later built DTRs.
If you have early build DTR600/700 radios and are encountering random lockups, try disabling the battery saver in the CPS.
