It may happen that the device continues to run with internal capacitors during the battery change and therefore does not recognize that a new battery has been inserted. This will also not reset the internal charge counters and the device continues to display "Low Bat" with the new battery.There are two solutions for this:
oAfter the old battery has been removed, wait for about 1 minute. The internal capacitors will be discharged.
oAfter the old battery has been removed, push on the button for 3 s, the capacitors are immediately discharged.
