MAINTENANCE
Battery/Coin cell
The battery on the KarL4 is necessary for the date and time as well as for protecting the digital
keys. If it is necessary to change the battery, this must always be done with the power on, i.e.,
with the MDB cable plugged in and the machine switched on or the battery plugged in.
