Operation Panel Details
ON/OFF switch

Battery lamp
Rotation Speed lamp
Power/Rotation Speed Selector switch
Pressing this switch, when the power is on, rotates the motor handpiece, and re-pressing the
switch stops the handpiece. (Normal rotation operation) Pressing and holding the switch for
approx. one second or longer rotates the motor handpiece and releasing the switch stops the
handpiece. (Temporary rotation operation)
· ON/OFF switch
Pressing and holding the power switch for 1 second or longer, when the power is off, turns on the
power, and re-pressing and holding the switch for 2 seconds or longer turns off the power. In
addition, by pressing the switch, when the power is on, the rotation speed can be selected.
· Power/Rotation Speed Selector switch
This lamp lights when the battery charger is connected, and flashes when the battery voltage
lowers. It also flashes when an error occurs. (Refer to "10. OPERATION PANEL DISPLAY" )
· Battery lamp
It lights the set value of the lamp
at the present rotation speed. It
flashes slowly while the motor
handpiece rotates. When two
lamps light simultaneously, it
means that the rotation speed is
between the two lit values. If one
minute passes under a
non-operational condition after
the rotation of the motor
handpiece stops, the lamp for
the presently set values begins
to flash slowly.
