3. Refer to "Initial Set-up" 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 main display unit. The power and the display
of both turn on.
5. Check that [EAL] appears on the main screen of the motor
handpiece. Motor handpiece and main unit are connected
correctly. If the [EAL] does not appear on the screen,
check the Troubleshooting Guide.

Setting the Linkage
Set the motor operation options when using the device in
conjunction with the Apex Connect.
1. On the main screen of the motor handpiece, press the
button for 2 seconds. The linkage settings appear.
2. Press the [ ] button until the desired menu appears, then
press the [ / ] button to select a value.
3. [Auto start & stop]: Set whether to operate the motor
depending on the location of the file.
• [On]: The motor operates when the file is inserted into the
root canal, and the motor stops when the file is pulled out
from the root canal.
• [Off]: The motor does not run even if the file is inserted
into the root canal. Regardless of where the file is, the
[Main] button to operate the motor can be pressed.
4. [Apical action]: When the Apex Locator measurement
approaches the APEX reference value during root canal
instrumentation, the speed of motor and the torque of the
motor decrease so that the root canal does not instrument
deeper than the set value.
[Speed slowdown]: When the Apex Locator measurement
•
approaches the APEX reference value, the motor's
rotational speed decreases.
• [Torque slowdown]: When the Apex Locator
measurement approaches the APEX reference value, the
motor's torque limit decreases.
• [Off]: The motor operates the same regardless of whether
or not the Apex Locator measurement approaches the APEX
reference value.
5. Press the [Main] button. The settings are saved, and the
device returns to the main screen.

Using Linkage
1. 1. Refer to "USING THE DEVICE > Basic functions" in the
Elements Connect Endodontic Motor Instructions for use to
set the memory number and the motor operation method.
2. Place the lip hook on the lip opposite the tooth to be
worked on.
3. Slowly insert the Ni-Ti file into the root canal. The root canal
length is measured, and the Apex Locator measurement is
displayed in the

NOTE:
To measure root canal length only,
be set to [Off]. For more information on how to set the motor
operation, refer to "Setting the Linkage" in this manual.

reference value, an alarm will beep rapidly.
• If the reading reaches or passes the value of the APEX
reference value, the alarm will beep continuously, and the
screen will blink.

direction of the current setting.
• The motor rotates in the opposite direction only while the
button is pressed and stops when released.
• Here, the operation screen does not appear on the display,
and the main screen remains on.
5. To end use, press any two buttons on the motor handpiece
at the same time for 2 seconds, then press and hold the
button on the Apex Connect Unit. The power and the display
of both are turned off.

• These values represent the APEX reference value and the
measurements taken by the Apex Locator at the file' s
current location. The measured value is also displayed
numerically on the right side of the screen.
• When the measured value reaches the APEX reference
value, the motor operates as follows.
• [R&S]: The motor stops after rotating in the opposite
direction of the current setting.
• [REV]: The motor rotates in the direction opposite to the
current setting. It then rotates in the set direction again.
It is the torque value of the motor in operation and the torque
limit value set in the memory.
