hi all
i realy need your help with my HM-801.
Since yesterday suddenly my baterry is not charging and now it is empty so i don't have access to my HM-801.
I check my charger with a volt-meter and got on both pins a measurement of -9.0V.
Each pin of the charger connector to the HM-801 has an inside and outside areas, i measured each pin with the positive probe on the outside and the negative probe on the inside of the pin
Is there a problem with my charger? i would expect the measurement to be +9v and -9v.
I repeated the measurement several times to verify the results.
please help me to identify the source of the problem:
1. is it a problem with my charger?
2. is it a problem with my HM-801 charging circuitry?
3. or is the problem with my battery? (doesn't the device should work with only the charger connected to it?)
and one last thing, I think my firmware is V0.21 but i'm not sure. i saw at the head-direct site that this version fixed a bug with the battery charging controller. http://www.head-direct.com/News/?act=detail&id=214
can any one elaborate about this bug? can it be the source of my problem.
thank you in advance
