13. Operation
13.1 The handpiece powers up when it detects motion, i.e. when the user picks it up. If not in use, it will shut
down again after a minute.
13.2 Load the DPA with prophy paste and depress the foot pedal slowly to avoid splatter. The DPA (motor) will
only rotate in one direction.
13.3 Adjust pressure on the foot pedal to control the rotation speed of the DPA throughout the procedure.
13.4 Follow standard prophylaxis procedures as you would with any corded prophy device.
13.5 Applying excessive force to the polishing surface may slow or stop the rotation of the DPA and result in
ineffective polishing.
13.6 The Handpiece Cradle should be placed on the instrument tray so that the Handpiece may be placed in it to
avoid the handpiece possibly rolling and falling off the tray during a prophylaxis procedure.
NOTES:
• If the handpiece seems to be losing power, recharge as
soon as possible.
• If the handpiece battery is completely discharged, the
three LEDs will blink and the unit will shut down. The
handpiece must be put in the charging base before it’s
able to operate again.
