2 Notice of installing and using the device
2.1 Please read the instruction manual carefully before the operation.
2.2 When the indicating bar reaches the position of the dial 0.0, and there is
"APEX" on screen, the endo file has reached the anatomical apical foramen. To
guarantee the safety, the work length is clinically obtained by subtracting 0.5-1mm
from the length measured by the Apex locator.
2.3 The scales 0.5 and 1.0 on the screen dial do not indicate that the distance to
the apex is 0.5 mm or 1.0 mm. It just reminds the operator that the file is getting
close to or away from the apical foramen.
2.4 If the screen bar graph suddenly makes a large movement or immediate
display ‘OVER’ in the upper part of the canal, continue slightly towards the apex so
the signal returns to normal.
2.5 In order to prevent leakage or interference between the root canal and
resulting in inaccurate measurements, dry the access cavity with a cotton pellet or
air-blower before each use.
2.6 Use a file size adapted to the root canal diameter. The selected file is too small
for a large root canal might cause the screen digital display is not steady during the
procedure.
2.7 In order to confirm the file clip and measuring wire makes good contact, test
the wire connecting before each use(See 3.1.2).
2.8 The file clip, lip hook and touch probe, Pulp tester probe are reusable. Please
make sure they are autoclaved under high pressure and high temperature before each
operation. The endo files should not be used more than 3 times.
2.9 The batteries must be taken out for storage when the device is not used for a
