INFORMATION
Before inserting the new battery, wait about 30 seconds. Please make sure, that the contacts
are metallically bright and free from coverings which result from bleeding or gassing batteries.
Grip the new batteries only with plastic forceps, if possible not with the hand due to the forma-
tion of oxide and never with metal forceps in order to avoid a short circuit. In most cases the
round cell will be inserted into the digital display with the marking upside. After inserting the
round cell, the battery compartment has to be closed again.
