Got my pcm9x soaking wet (flying in the rain) stupid I know, anyway it died on me the next day just as I fired up my BGX powered Diabolo, luckily the engine stopped while I had hold of the model.
Got home and removed the back cover and dried it out, there were water drops everywhere, switched back on and all I had was a blank screen and a series of beeps, thinking I had permantly killed something started to panic but then thought perhaps the processor circuitry needs to be re-initialised as there were the beeps, I found by holding down one of the front buttons (can't remember which one) the TX fired back into life and the screen came back on - phew !.
But after re-programming one of the Model Memories (All my 10 Model setups were gone) found everything seems to be working fine but on the main display instead of where it should display the model name it says UNAJUST which is highlighted. So I sent a mail to macgregor service dept and they say it sounds like the memory battery has died but I don't think so because it has held the Model setup I have just programmed Does any body know what this UNAJUST means

UNADJUST on the 9X is indicative that the lithium has died and that the processor has lost its reference settings ( A-D Converter offset, stick gain offsets ).

The fact that the system had a "dead" display and restored itself after you pressed the clear button verifies the above.

The main battery will charge up the memory and the system will retain it for a few days, but that will be lost shortly.

Send it in to me and I will fit a new Lithium and recalibrate the system and hopefully no other damage has been done.

pcm9x problem reply
Thanks Mac_Man for your quick reply

I assume you are a macgregor employee from your location

I am a electronics engineer aswell and was wondering if I could replace the lithium myself rather than send the tx back just for that (due to loss of flying time etc) but was wondering how/what would need to be recalibrated ?

thanks
