Changing Batteries
Prepare small screwdrivers
1. Turn off the power of the motor handpiece.
2. Remove the rubber cover from the battery cover with
a thin flatblade screwdriver. (Fig. 13)
3. Remove the screw fixing the battery cover with a
screwdriver. (Fig. 14)
4. Remove the battery cover by sliding it toward the
charging terminal. (Fig. 15)
5. Remove old batteries.
6. Insert new batteries according to the polarity mark-
ing in the battery box. A mix-up between the plus
and minus sides will not allow operation of the hand-
piece.
7. Attach the battery cover.
8. Tighten the screw with a screwdriver. Do not over-
tighten it.
9. Insert the rubber cover back into the screw hole of
the battery cover in the originally inserted direction.
Changing of batteries is now completed. Charge them
fully before use.
CAUTION
- Do not misplace the rubber cover and screw.
- The used nickel metal hydride batteries are recyclable, but their disposal may sometimes not be permit-
ted by the respective country. Return them to your dealer.

12. Error Code
If the motor handpiece stops due to an abnormality such as a malfunction, overload, break or wrong use, it
automatically checks the state of the control unit and detects the cause of the abnormality and displays an
error code on the LCD panel. If an error code is displayed, turn on the power again and check whether the
same error code is displayed. If the same error code is displayed, take action by referring to the instructions
provided in the "Check/Remedy" column in the following table.
