For information of everybody it has been confirmed that the problem of my ET 9000 was due to battery cell 3V dead , i asked to my reseller who gave me that company to repair the box:

elicom gmbh email: emde@elicom.de tel: 069-33997596-0

 

it costs me 58 € (including 17 € of delivery cost) .

 

Thanks for the information, link stored for the unforeseen future ;(

 

That makes a the purchasing price 58 Euro's more for a feature that the customer did not wanted and needed.

I wil keep it in mind when I buy my next box, probably not an Xtrend

You can change battery if you solder on a second battery holder to put new battery inplace before removal. In case old battery short the new battery it might be better to solder on two new battery holders via zener diodes. And move to using one of those when the supplied battery is still at 3volts. I am 1,3 volts after just 2 years, so for me it is too late. They not stay above 1,8 volts for the arm processor to survive it's memory of key codes.

Or you might try have the box on and powered up when you change battery. According to arm processor specification that memory of keys is powered from other supply when processor is running from external power. Battery is only in use when box is off. All at your own risk, but by studying the design this is my conclusion.
