(4) Calibration
This function is to decrease fluctuation in the rotation speed of the motor handpiece and the difference in torque by
the contra angle head.
1) Lubricate the contra angle head with the spray. (Refer to the “P14 7. (1) Lubricating Contra Angle Head.”)
2) Turn off the power if the power is on.
3) Connect the AC adapter and confirm that the AC IN lamp lights.
4) Turn on the power.
5) Hold down both buttons of the SPEED key simultaneously for more than one second.
6) The LCD panel displays “ ” with the alarm sound.
7) Attach the contra angle head to the motor handpiece and press the MEMORIZE key.
8) If the motor handpiece begins to rotate, leave it as it is until it stops.
9) This process ends, if the rotation stops and the LCD panel display returns to its original state.
10) If you want to stop this process, turn off the power.
(3) Battery Refresh
Nickel-metal-hydride batteries may result in a decrease in charging capacity, if additional charging (repeating a cycle
of short-time use and recharging) is made. (Generally, this phenomenon is called a “memory effect.”) This Battery
Refresh function is to resolve this phenomenon.
1) Turn off the power if the power is on.
2) Connect the AC adapter and confirm that the AC IN lamp lights.
3) Hold down the POWER key for more than one second, while pressing the REVERSE key.
4) The alarm sounds for a length of time, and the refresh mode is activated. At this time, the mark of the remaining
amount of the batteries on the LCD panel is animated in the direction opposite to display at the time of charging.
At the same time, the CHARGE lamp flashes slowly.
5) Leave it as it is. The batteries are discharged and recharged automatically.
6) Hold down the POWER key for a while, when you want to stop this process. (At this time, the power does not turn on.)
• Lubricate the contra angle head before Calibration.
• This function does not operate if AC adapter is not used.
• Do not touch or apply a load to the rotating shaft of the contra angle head. It obstructs accurate measurement.
• This function cannot completely absorb the individual difference of the actual motor handpiece and contra angle head.
NOTICE
• This function is not activated unless this product is powered by the AC adapter.
• If this function is used, all programs will disappear and return to the originally set values. Record the present
program details according as needed.
NOTICE
• This function is not activated, if not driven by the AC adapter.
• It may take up to 5 hours to discharge batteries.
• It takes 5 hours to discharge and 5 hours to recharge. Therefore, total of about 10 hours are required. For
example, if dental treatment is finished at 7 p.m. and the refresh mode is set, the batteries will be fully
charged by 5 a.m. the next morning at the longest.
• This function is not required for each charging. Try this function, if the operating time is shortened even if the
batteries are relatively new.
• Do not repeat activation and deactivation of the refresh mode in a short time. It may result in enhancement of
the memory effect.
• This function is fully effective for solution of a “memory effect.” However, it cannot be solved completely at
one time due to characteristics of batteries. We recommend you repeat this process a few times according
to need.
