Do you have any cables plugged into the CAT jack or data jack? That can cause problems if RF gets back into those cables.

Has anyone else ever experienced a random factory reset like this? Any other potential cause?

ESD. A ?static discharge will wipe out the EEPROM.? 24LC128 right beside the microprocessor. ?I have done it myself on the bench here on a Cold Feb Afternoon. ? It is winter. Dry.?

Too bad a simple Reed-Solomon subroutine, built in, couldn’t solve this dilemena.
Most well written software has what is called a hook routine where if the processor encounters? corrupted data it jumps to a safe start point rather than lockup with no way out. I suspect in the case of the 857 it is the non volatile part of the software where it will reload the factory default. The volatile part part of software can be corrupted by RF getting into the radio, common mode currents etc. Doing a reset is a good thing although it's annoying but warns you there is possibly an external problem.

Typical mobile installation. 12v direct from the battery/ground. Remote head. No tuner. Only connected (at the time) for vhf/uhf. Been installed like this since July of last year and no problems. Rotate it the radio b/t three vehicles and last programmed it via CHIRP 5 years ago and never saw anything like this before.

Tim,
I have 3 and have never had that happen that I can remember, give us a bit more info on your set-up may be helpful, I.E. power hookup are you running a tuner and so on.

I realize this is an old post , but...
Here is my version of the problem:
1. power on button shows RED
2. display flashes "TOT"
3. pressing power button? clears everything
4. pressing power button resumes normal opertion
5. display? reads? 13.6V? += .1 V
?
Suspect - lousy / lossy power connector - not surprising.
?
Main question
what the heck is flashing "TOT" telling ?

Re: blinking display on power up
Maybe your MENU 084 is not at OFF but as a
value ?

Re: FT857 remote operation?
Bart,
I connect to the radio with a USB dongle made doe the Yeasu Radios. It works with my laptop. When I connected it to my Android phone via an OTB cable he com port is detected but I cannot control with the pRXTX free version. HAs anyone controlled their Yaeus Ft-817, 818, 857 or 897 with the free version?
