DT71 Mini Digital Tweezers not booting when placed on the ar

Post by simejis »

***** SO#: 770365 *****

Hello,
can you possibly help on a customer issue with the DT71 tweezers?
The customer told us:
-----
The control unit did not turn on when placed on the arms.
When charging the arms, the red LED lights up and indicates an active charging process.
After several hours, the LED remains red, but the control unit still does not boot when placed on the arms.

The control unit boots when connected to the PC and shows DFU:V3.53; 4.718V.
Also I had success to flash the firmware to version 1.15.
But still no function when connecting the arms.
Tip on a defect of the built-in batteries?
------

Would this require to have the tweezers replaced?

Thank you very much.
Best regards
Adnan

There is a factory reset that might help before we get into replacement.
