AUTO REVERSE OFF
The motor handpiece stops without reverse rotation. If you want it to rotate (forward-rotate) again, re-
press the ON/OFF Key or re-step.
CAUTION
- When the battery charge goes down, the actual load may not reach the preset torque limit value. In this
case this auto reverse function will not be activated.
- If a load is continuously applied to the motor handpiece, it may automatically stop to prevent overheat-
ing. In this case, leave the motor handpiece for a while until it cools down.
- If the ambient temperature is low, the alarm may sound when the motor handpiece rotates, however,
this is not a failure. If the alarm does not stop sounding even when the ambient temperature increases,
clean the contra angle head and perform calibration. (Refer to 6 (3) Calibration)
(6) Completion of Medical Treatment
When the treatment is completed, return the motor handpiece to the handpiece stand and hold down the
POWER key for more than one second to turn off the power.
Auto Power Off
If the key is not operated or approximately 10 minutes passes during rotation with no-load, the power is
automatically turned OFF to save energy and prevent improper operation. However, if load is applied dur-
ing rotation of the motor handpiece, the power is not turned OFF even during no operation.
LAST MEMORY
The last setting used before the power is turned OFF is memorized. The setting when the power is turned
ON next is as that immediately used before the power has been turned OFF.
6. Convenient Function
(1) Program
You can change any preset values and have them memorized to your desired settings (rotation speed,
torque limit value, gear ratio and auto reverse mode)
1. Press the PROGRAM key until it turns to the program number which you want to have memorized.
2. Adjust the rotation speed, torque limit value, gear ratio and auto reverse mode by UP/DOWN key accord-
ing to your needs.
3. Hold down the PROGRAM key for more than one second. When the alarm sounds the settings have been
memorized.
NOTICE
- The program cannot be memorized while the motor handpiece is in motion.
- The program is not memorized unless the PROGRAM key is held down for more than one second. If the
program number is changed by the PROGRAM key, the initially memorized preset values remain. (Cancel
function)
(2) Initialization of Program (Factory-set configuration)
The program can be returned to the original state configured at the time of factory shipment, if setup be-
comes confusing.
1. Turn off the power, when the power is on.
2. Hold down the PROGRAM key and ON/OFF key for more than one second, while pressing the POWER key
at the same time.
3. Release the keys when the LCD panel indicates "
played.
4. Initialization is completed, when "
"is displayed.

", and re-press the PROGRAM key while this is dis-
NOTICE
If this function is used, all programs will disappear and return to the originally set values.
Record the present program details if required before you carry out this operation.
(3) 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. (Refer to the "7 (1) Lubricating Contra Angle Head. " )
2. Turn on the power.
3. Hold down UP/DOWN key simultaneously for more than one second.
4. The LCD panel displays "
" with the alarm sound.
5. Attach the contra angle head to the motor handpiece and press the ON/OFF key. (Remove the bur or
TEST bur.)
6. If the motor handpiece begins to rotate, leave it as it is until it stops.
7. This process ends, if the rotation stops and the LCD panel display returns to its original state.
8. If you want to stop this process, turn off the power.
NOTICE
- This function does not work unless remaining battery capacity is sufficient.
- Perform calibration after cleaning the contra angle head. Residual contamination on the rotating shaft
will impair correct measurement.
- Do not touch or apply a load to the rotating shaft of the contra angle head. It will obstruct accurate
measurement.
- This function cannot completely absorb the individual difference of the actual motor handpiece and
contra angle head.
(4) Alarm Sound Volume Control
Setting alarm sound
You can turn ON/OFF the alarm (load alarm) which sounds near the torque limit value when the motor
handpiece rotates and the alarm during auto reverse (auto reverse sound).
1. Turn off the power
2. While pressing SELECT key, keep pressing POWER key one second or more.
3. The alarm mark
and ON or OFF on the LCD panel, and the sound volume changes.
4. Press the SELECT key to select ON or OFF for alarm sound.
5. Display on the liquid crystal panel (LCD) returns to the original state if no operation is performed for a
while.
NOTICE
The volume setting is memorized automatically to the last setting and remains unchanged even if the pow-
er is turned off.
