OPERATION:
After the unit has been set up and you have made yourself
familiar with the operation functions, you are ready for opera-
tion as follows:
SETTING UP THE UNIT:
1. Unpack the unit and verify that it carries the proper certifica-
tion markings.
2. Open the battery door on the back of the unit using a Phillips
head screwdriver. Install the enclosed 9V battery (for approx.
5 hours of use). The unit will accept three 9V batteries,
resulting in battery life of approximately 15 continuous oper-
ating hours. Close the battery door and secure with screw.
NOTE:
The blinking “target indication is set to the “APEX”
indication at the factory. This setting can be changed upward
by adjustment through the set access opening in the back of
the unit. This does not change the performance of the unit
as programmed based on collected clinical data. It does pro-
vide a means to accommodate a preference for a different
“target” indication from the canal.
3. Connect the Cable Assembly to the connector jack on the
side of the unit.
4. Connect one lip probe to the gray receptacle jack on the
cable assembly.
5. Connect one Autoclavable E-ZHook
TM
file clip assembly to
the white receptacle jack on the cable assembly.

OPERATION (Continued):
1. Press the power switch in the upper right hand corner of the
unit. The power indictor will turn red and yellow during self-
test. Successful completion of self-test is signified with a
quick sequence of light illumination on the front panel and an
audible indication if sound is turned on. The power indicator
will turn green indicating the unit is ready for normal opera-
tion. The self-test sequence should take only a few seconds
to complete.
2. Attach the stainless steel lip probe securely to the patient’s
lip at the corner of the mouth. Secure contact to the patient’s
oral mucosa is crucial for an accurate measurement reading.
3. Attach the file clip assembly to a file or reamer. Attach the file
clip to the upper part of the file near the handle. The cutting
part of a file can damage the file clip.
4. Verify all cable assembly connections are secure to the lip
clip, file clip and the unit. A poor connection can prevent
accurate measurement. Do not pull on the cords of the cable
assembly when attaching or removing the clips or when dis-
connecting the cable assembly from the unit. This could
compromise the electrical connection integrity inside the
cable assembly.
5. Insert the file (usually size 10) into the root canal until the
unit indicates one bar above apex target. Advance the file
with slow clockwise turns until Apex is indicated.
6. Illuminating the red L.E.D. bar at the bottom of the indicator
column with a solid audio tone, if sound is activated, indi-
cates perforation.
7. Turn the file with slow counterclockwise turns until the unit
indicates one bar above apex target again. This procedure
will provide assurance that the apical constriction has been
identified and the indication is not due to a non-apical con-
striction inside the canal.
8. Position the file marker on the surface of the tooth as a refer-
ence to determine the canal’s working length.
9. Press the power switch again to turn the unit off. The unit will
automatically turn off after 20 minutes of no display activity.
10.Always take an x-ray to check the results.
