Replacing the lithium battery
Clock problems are in most cases
caused by a weak lithium cell. To
replace the cell, open the unit as
described under chapter "fault finding
procedures". Use a small screwdriver
to lift the cell from its socket. Remove
the cell by sliding it away. Replace by
3 Volts cell type CR2025 only.
