PREPARING THE DEVICE
1Preparation and Use Environment
The environmental information appropriate for using this device
is as follows.
•Appropriate temperature: 10–35°C (50–95°F) / Appropriate
humidity: 30–75% / Atmosphere pressure: 700–1060 hPa
•Do not use the device in a place that it is exposed to direct
sunlight, heat sources, or near a fire.
2Assembly
•Charge the battery sufficiently when using the device for the
first time or after long-term storage.
•Be sure to charge the battery using the power cord and
AC/DC adapter included in the package.
•Sterilize the lip hook and file holder when using the device
for the first time and after every patient.
•Examine the role of each USB connector on the probe cord
and connect to the appropriate device.
•Ensure the file holder and lip hook are properly connected
to the probe cord.
NOTE:
•Refer to “Charging the Battery”on page 3 for more
information on how to charge and replace the battery.
•Refer to “Assembling the Device”on page 3 for more
information on how to mount and remove the lip hook and
file holder.
USING THE DEVICE
1. Refer to “Initial Set-up”to connect the lip hook and file
holder to the device.
2. To turn on, press the [ ] button on the left side of the
device without the file holder and lip hook touching
anything.
PRECAUTION
If the device is powered on while the file holder and lip hook are
touching the object, the calibration function will not start, and
[Er] is displayed on the measurement screen.
3. With the clip of the file holder B touching the lip hook,
ensure that the figures and graphs are activated on the
measurement screen.
4. While holding down the [Push] button on file holder B,
insert the file according to the shape of the clip.
PRECAUTIONS
• Use a stainless-steel hand file (k-file).
• Do not use deformed or damaged files.
5. Gently pull on the file to confirm it is secured.

56
PRECAUTION
If the file is not properly secured to the file holder, the file may
become detached during use and may result in inaccurate readings.
6. Place the lip hook on the lip opposite the tooth to be
worked on.
7. Slowly insert the file into the root canal, checking the
information on the measurement screen.
• Refer to “Measuring Working Length”on to measure
the length of the root canal.
• When measuring with file holder A, confirm that the file is
connected to the metal part under the file handle.
PRECAUTIONS
• When measuring the root canal length, the file length may vary
depending on the operator's viewing angle.
• After root canal instrumentation, the length of the file may differ
from the measured angle of the original working length. After
instrumenting the root canal, check the working length again.
8. When finished, press, and hold the [ ] button for
2 seconds. The display turns off.
9. Press the [Push] button on the file holder B to remove the
file from the clip.
10. Refer to “Disassembling the Device”to remove the lip
hook and file holder from the device.
11. Refer to “Cleaning, Disinfection and Sterilization
Instructions”to manage the device.
1Measuring Working Length
1. Slowly insert the file into the root canal while checking
the readings.
• When the file approaches the APEX reference value, an
alarm beeps.
• When the file reaches or passes the APEX reference
value, the device will sound the alarm continuously and
measurement screen and file holder will flash at the
same time.
• The measured value range and corresponding color will be
shown on the display with the file holder lamp.
See Table Below.
Lamp Color Lamp Status Measured value range (mm)
Blue On 3.0–1.1
Yellow On 1.0–0.1
Red On 0.0– -0.5
2. Once the distance between the file and APEX reaches the
APEX reference value, stop inserting the file, place the
rubber stopper of the file on the reference point of the tooth,
and then remove the file from the tooth.
3. Use an Endo ruler to measure the working length between
the end of the file and the rubber stopper.
NOTE:
Use radiographs to check the working length.
Different results from radiographs than the results obtained from
the measuring device may be shown.This is not a malfunction
of the measuring device. It may be due to the anatomical apex
and/or the physiologic apex may be located coronal to the
radiographic apex, or there was a misalignment of the angle of
the X-ray beam and the film. (See Figure 1)
2Helpful Tips to Avoid Measuring Errors
•Before measuring root canal length, remove any exudates
such as blood from the root canal.
•Before measuring the root canal length, be sure to dry the
pulp chamber around the root canal opening.
•If the root canal is completely dry, the actual length and
measurement may differ. Fill the inside of the root canal
with saline water and measure.
•After inserting the file to approximately half the length of
the root canal, attach the file to the file holder.
•When measuring the root canal length, start working with a
thicker file. If the reading does not reach the APEX point, use
a thinner file to measure the root canal length.
•During root canal length measurement, be mindful of the
errors that may occur if the file touches a metal restoration.
•The presence of necrotic dentition and cementum within
the root canal can affect the measurements. Measure
several times, extending the root canal with a file of the
appropriate thickness.
•If the root canal is not fully formed or is over instrumented,
the measurement of the working length may be shorter
than the actual measurement.
•To obtain a more accurate measurement with minimal error,
measure at least twice.
•If the root canals within the tooth are connected, such as
a multi-root canals or the tooth has a crack, it may affect
the measured value and cause an error. Use a radiograph to
check the structure of the tooth, including cracks
USER ENVIRONMENT SETTINGS
Follow the steps below to set the user environment for the
Apex Connect unit
1. With the device powered on, press, and hold the [ ] button
for about 2 seconds. Entering the settings mode, the figures
and graphs flash on the display.
2. Press the [ ] button to select the APEX reference value, and
then press the [ ] button. The settings are saved, and the
volume icon blinks.
• The APEX reference value is displayed as a line on the graph
on the measurement screen, and this line can be used as an
estimate of the working length of the root canal.

56
• APEX reference value can be set between -0.5 and 1.0 mm.
(Default: 0.0 mm)
• The default setting of the APEX reference value which is 0.0
means that the file has reached the anatomical foramen
(apical constriction) and is approximately 0.5 mm away
from the physiological foramen (apical foramen).
3. Press the [ ] button to select the alarm volume, and then
press the [ ] button. The settings are saved, and the
value flashes.
• Set the alarm volume between 0 and 3. (Default: 2)
4. Press the [ ] button to select the standby time, and then
press the [ ] button. The settings are saved and returned to
the measurement screen.
• Set a standby time so that the device turns off after a
certain period of inactivity.
• The standby time can be set between 2 and 10 minutes, in
2-minute increments. (Default: 4 minutes)
ADVANCED SETTINGS
1Linking the Apex Connect to the Elements
Connect Endodontic Motor
This device can be used in conjunction with Elements Connect
Endodontic Motor, by connecting the two devices, the
instrumentation and enlargement of the root canal can be
performed while checking the working length of the root canal.
PRECAUTIONS
• This device is designed to be compatible with Elements Connect.
Do not connect any device other than Elements Connect.

Sterilization Instructions”.
3. Refer to “BEFORE USE > Using Accessory”in the Elements
Connect Cordless Endodontic Motor Instructions for use
to attach the contra angle and Ni-Ti file to the motor
handpiece.
PRECAUTION
When selecting the proper file length for the procedure, note that
the total working length of the file is reduced by 2mm due to the
deep set insert in the contra angle head and might difficult the
repositioning of the silicone stopper. A longer file might have to
be selected.
4. Press the [Main] button on the motor handpiece and the
[ ] button on the Apex Connect Device. The power and the
