The battery fitted on the unit is a surface mount CR1220 battery -unlike other memory batteries on computer based hardware, this type does not allow users to simply replace the battery, as the battery holder and battery are one entity that is soldered to the main PCB as illustrated in this image below:

To complicate matters, if this arrangement is disturbed with the power off, all your settings will be lost and cannot be retrieved.

To retain your settings the battery must be changed with the power on, it is for this reason that Klark Teknik strongly recommends only qualified official Klark Teknik service engineers perform this task as there is a personal danger of electrocution as well as damage to the unit.
