4.1 Connecting file clip, lip
hook and extension cord
Connect file clip, extension cord
and lip hook to APEX locator as
shown in the picture. Also, use
both extension cords according to
actual situation.
NOTE
Please use the original file clip
and lip hook that manufactured
by Sifary. Because the size of the
unoriginal file clip and lip hook
are different, it may damage the
APEX locator or cause deviation
of measurement accuracy.

6.1 Charge
Display the present remaining
amount of the battery.
Less than 15% remains, please
charge.

device must be recharged within 30
days, otherwise the battery will be
damaged.

6Operation
Page 14 / 41
Charging indication appears on the
screen, and flashes slowly, when
battery is fully charged or in a state
near full charge, the flash will stop.
Fully charged will take about 4-5
hours, depending on residual
battery power and battery state.
It can be recharged 300-500 times,
depending on the operating
conditions of the device.
WARNING
Do not change the battery, only
trained technician or distributor can
change the battery, the electronic
parts will be damaged if use a
wrong battery or install with a
wrong way.

6.2 Function checking of APEX locator
After turning on, insert the
tester into the APEX locator.
Clamp the groove of tester
with file clip.
The measuring bar on the
screen flashes at point 02, 03
or 04.
Recommend to test the APEX
locator with tester once a
week.
NOTE
If the measurements are not
expected, check that the tester is
connected properly. If the normal
connection still does not show the
expected value, please stop using
the device and contact the local
dealer for processing.

6Operation
Page 16 / 41
Confirm the device with short
touch file clip and lip hook
before.
Confirm that the tester is not
installed on the APEX locator.
Then connect the file clip, lip
hook and extension cord
according to chapter 5.1.
Finally, touch the lip hook with
exposed metal position on file
clip, the measurement on the
screen should be shown as -
2.
NOTE
If the measurement shown is not -
2, check that the connection is
normal. If the normal connection
still does not show the expected
value, please stop using the
device and contact the local dealer
for processing.

6.3 Operation and not suitable condition
Press the back cover of the file clip to make
the hook of the file clip stick out. And hook the
metal handle of the root canal file. Release the
pressure and use the elasticity of the file clip
to complete the connection between the file
clip and the root canal file.
NOTE
When connecting the root canal file, make
sure that the file clip and the root canal file
handle are basically perpendicular, otherwise
the chuck of the file clip will be easily
damaged.
This equipment does not include the root canal
file. We need to buy another suitable model
according to the clinical needs. The metal part
of the root canal file should be well conductive.
When the file clip can’t enter the patient’s
mouth, the file clip can be replaced by the
extension cord with the touch probe. Press the
touch probe on the metal handle of the root
canal file to complete the connection between
the touch probe and the root canal file.

6Operation
Page 18 / 41
Hook the lips to the patient's lips. Ensure
contact with the lips fully. Then the root canal
file is slowly inserted into the unblocked root
canal.
If the patient is fitted with a metal crown or
other conductive devices, the root canal file
clip and the metal part of the file clip should not
be in contact with it, so as to avoid causing
wrong measurement results.
APEX locator should be fixed in patient’s collar
with the clip.
NOTE
To prevent measurement errors caused by
conduction between the gums or adjacent root
canals, dry the pulp chamber floor with cotton
balls or other means before testing.
Using the correct number and taper of the
canal file, make it fully contact with the canal
wall, is conducive to accurate measurement.
As the root canal file is inserted, the
measurement bar on the screen lights up from
top to bottom.
When displayed as shown in figure 1, the

6Operation

value of the reference range is 2, indicating
that the distance from the tip of the tooth root
is about 2mm at this time. At the same time,
theAPEX locator emits a "di" alarm sound at a
long interval.
When displayed as shown in figure 2, it means
that the distance from the tip of the tooth root
is close, about 1.5 mm, and the time interval of
"di~di~" alarm sound emitted by the APEX
locator becomes shorter.
When displayed as shown in figure 3, it means
that it reaches the tip of the tooth root. The
measured value is 00, which is the actual
length of the root canal to be measured.
When displayed as shown in figure 4, it means
that the root canal file has gone beyond the tip
of the tooth, and the main body emits a very
urgent "di~~" alarm sound.
NOTE
The tip of the tooth root position (measured
value: 00) measured by this device is the
Major/Anatomic apical foramen. In clinical
practice, in order to prevent surgical failure
caused by piercing the root apical orifice, 0.5-
