• The motor handpiece is designed with the commercially available AAA nickel metal hydride
batteries (rechargeable). Ni-Cad batteries can also be used, but the charging time and operating
time become significantly shorter since the charging current differs.
• The motor handpiece consumes electricity very slightly even when the power is off. In addition,
fully-charged rechargeable batteries, in general, discharge gradually over time even though it is
not used. It is recommended to recharge the batteries just before use.
• When the motor handpiece automatically stops by detecting a low battery voltage, leaving it for a
while and turning on the power again may not detect the low voltage immediately. This is not a
failure, but is due to battery characteristics. Since the voltage drop does not coincide with the
remaining battery capacity, consider it only as a yardstick.
• Recharge rechargeable batteries after they deplete as much as possible. Repeated short-time use
and subsequent recharging may shorten their operating time due to a "memory effect." Batteries
may recover after repeating complete discharge and full charge a few fimes.
• If you do not use the product for a long period of time, remove the batteries from the
motor handpiece.
NOTICE
• Compact body.
• Operable continuously for approx. one hour at rated load. (Dependent upon conditions.)
• Operation panel values are memorized.
• Normal operation of the motor handpiece includes pressing the switch turns on the handpiece
and re-pressing the switch turns it off. In addition, temporary operation is available : pressing
and holding the switch turns on the handpiece and releasing the switch turns it off.
• The motor handpiece softly starts.
• Energy savings. The power of the motor handpiece automatically turns off after 10 minutes of
non-use. (Auto power-off function)
• The battery lamp indicates low battery voltage.
• The built in feedback circuit keeps the rotation at a constant speed even when a load is applied to
the motor handpiece changes.
• The contra heads provided for this product are all autoclavable at 135ºC (excluding the motor
handpiece).
