Hello,

Is this problem fixed?

Yes it is, definitely, for me at least.
Try to contact David, he will probably have you try some measurements on your unit.

In the meantime you can try changing to one of the four different settings of Power OFF mode (shift + 0 [setup], 5, 2, 7) and see if it makes a difference.
The magic number for me is "1".

Good luck!

This is my magic number as well. FWIW, my board is V3, Copyright Date 2017.

Hi all

I received my DM42 around two month ago and i realy like it. But the battery consumption is a nightmare.

It takes two batteries within these two month but was not seriously used. To be honest, with the second battery it was only switched on to check the battery voltage and then switched off again. I did this only once a day.

When the DM42 was out off power from the first battery (didn't show any live signal) i replaced the battery and checked the voltage with a multimeter. It shows 2.5 Volt which is very high for an empty battery.

With the second battery this behaviour was observed, too. I activated the voltage display in the DM42. Last time the calculator was alive the voltage was around 2.6V.

Obviously a calcuator with this amount of battery consumtion is not acceptable if one want to use it seriously.
I tried changing the POWER OFF mode to 1 (from default 3) but it seems not to show any difference (quite subjective observation, of course).

Does anyone have a suggestion how to get rid of this problem?

My Firmware is DMCP v3.13 (IFC 3.10) and the Program is 3.13/2.0.24. Hardware SN: 03910

Kind regards
Andreas

Contact David @ swissmicros
He will probably ask you to make some test on your unit (or find its version, maybe) and give you hints on solving this problem.
In the meanwhile you can try to cycle through the various settings in Power Off mode and check if you see any difference.
