Hello, this is my new trouble.
I’ve just replaced the battery and my DM42 doesn’t work anymore; if I attach the USB cable it switches on, only with battery no. Any suggestions?
Thanks for your help.

Re: Issues after replacing battery
May not be an issue, but is the battery in the correct orientation?
Do you have a way to test the voltage of the battery?

May be a bad battery nevertheless. Please see the thread about checking coin cells (under Discuss).

A CR2032 battery cell should measure at least 3.3 volts when new.
