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.
Remove the battery from the handpiece.
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.
Place the handpiece in the charger for 12 hours in
order to fully charge the new battery for the first time.
- The yellow LED of the charger illuminates after
approx. 2 sec; please see also "LED Display of the
Charger".
Solution
Clean the light guide and
the protecting glass in the
light guide mounting hole
(please refer to "Cleaning
the Light Guide").
