The LED´s show the position of the file tip:
Blue section (3 blue LEDs): coronal- median zone
Green/yellow section
(3 green/1 yellow LEDs): section from apical constriction to apical foramen
Red LED:
the apical foramen has been passed (over-instrumentation!)
Determine the apex at the 3rd green LED.
Audible warnings
While the file moves forward in the canal, the LEDs will be lit from the first blue to the third
green, accompanied by an intermittent acoustic signal at a frequency which increases the
closer the file is to the apex.
The yellow LED is accompanied by a continuous acoustic signal and the red LED by a very
strong intermittent acoustic signal.
NOTE
• A specific LED lit does not represent the working length in millimeters.
• To achieve precise measuring results, it is necessary to use files with the same diameter
as the apex. Files that are too small with respect to the true size of the apex can result in
unstable measurements.
Apical Auto–Stop
On delivery the apical auto-stop is inactive as default setting.

If this automatic function at the apex shall be activated, take the following steps:
• Press the MENU button and scroll with the + key until APEX appears at the left on the
display (marked with the arrow).
• Press the key until the arrow has jumped to the very right to “OFF”.
• Press the + key to switch from “OFF” to “ON” and confirm with the CONFIRM key.
If activated, the apical auto-stop makes sure that the rotating file tip automatically stops
when reaching the apex. By releasing the foot pedal and then again pressing the foot pedal
the file will automatically move into the reverse motion and shortly afterwards the file will
automatically move into the forward motion.
