(4) Preparatory Operations
1. Hold down the POWER key for more than one second
to turn on the power.
2. Keep holding down the PROGRAM key until program
No. suitable for file to be used is displayed.
3. When changing the set value of speed, torque, gear
ratio or auto reverse, press the SELECT key, select the
setting item and press the UP/DOWN key to change.
(5) Operation
If you press the ON/OFF key briefly, the motor handpiece
starts. If you re-press the key, it stops. (Alternate
operation)
If you hold down the ON/OFF key for more than one
second, the motor handpiece starts while the key is
pressed. If you release the key, it stops. (Intermittent
operation)
Auto Reverse Function
Auto reverse setting can be changed by pressing the SELECT key for one second or longer
while the motor handpiece stops. As the auto reverse mark flashes while the SELECT key is
kept pressed, press the UP/DOWN key to adjust it.
: Auto Reverse
: Auto Stop
: Auto Reverse OFF (flashes while the SELECT key is kept pressed, and goes out
when it is released)
The alarm will sound when it becomes a value of half of a torque limit set up during motor
handpiece rotation, and the alarm will change near the torque limit value. (Load alarm) When it
continues applying a load and it exceeds the torque limit value you can select mode from the
following three modes.
• 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 overheating. 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)
CAUTION
The GEAR RATIO key is fast-forwarded, when it is
continuously held down.

AUTO REVERSING
The handpiece stop that it reaches for the loaded value, the file rotates in reverse. When a load
is removed, the file returns to normal rotation (forward rotation) automatically

AUTO STOP
The motor handpiece starts in reverse. When a load is removed, the motor handpiece stops. If
you want it to rotate (forward-rotate) again, re-press the ON/OFF Key or re-step.
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.
