Maintenance and Care
Replacement of the Battery
Never place the handpiece in the charger without the
battery inserted in the handpiece!
Use 3M ESPE batteries only! The use of other manu-
facturer batteries or non-rechargeable batteries/
primary batteries is a potential hazard and may
damage the device.
Rotate the lid at the lower end of the handpiece
counterclockwise until it hits the stop, and then
remove the lid.
Push a small spatula or similar aid between the
cylinders of the battery until the snap-lock releases
so that the battery protrudes slightly from the hand-
piece body.

Use a different power
outlet.
Have the charger repaired.
Push the (replacement) battery into the handpiece
proceeding along the direction shown by the arrow
until the battery locks into place.
Replace the lid and close by rotating clockwise.
Insert the handpiece into the unit to completely
charge the new battery for its first use.
- The red LED of the charger illuminates after
approx. 2 sec; please see also "LED Display of
the Charger". The battery charging process is
complete once the red LED is turned off.
- Note: the new battery attains full capacity only
after several charging/discharging cycles.
Therefore, the battery charge may initially be
sufficient for a smaller number of exposures only.
