Calibration
Make sure the original contra-angle is installed before to launch the motor
calibration.
OFF: No action.
ON: Start motor calibration
The motor must be calibrated before the first use and after lubrification.
Beeper volume
The device sound volume can be adjusted from Vol. 0 to Vol. 4.
Vol.0: Mute.
Restore Defaults
OFF: No action.
ON: Device parameters returns to original setting.

Torque overload protection
During operation, if the measured torque load exceeds the torque limit, the motor will
automatically reverse the direction of rotation. The motor returns to initial Operation mode (CW)
when the torque load goes back below the torque limit.
4.7.1
Warnings
a)
In reciprocation motion mode (REC), when the load value is higher than the torque limit:
i.
if the Forward angle is greater than the Reverse angle, the motor automatically
switches to counterclockwise rotation (reverse direction).
ii.
if the Reverse angle is greater than the Forward angle, the motor automatically
switches to clockwise rotation (forward direction).
b)
The auto-reverse protection is not available for CCW and ATR modes.
c)
The auto-reverse protection might not work properly in case of low battery level.
d)
Under continuous load, the motor may stop automatically due to overheat. In that case,
the device must be powered OFF enough time to naturally cool down.

Apex locator limitations
Not all conditions are ideal for root canal length evaluation. Accurate signal cannot be obtained
if the root canal shows the conditions listed below.
