4. Usage
This manual will provide information on the operation modes of the micromotor: “Endodontic mode” and “EMR-interlock endodontic
mode.” For “normal cutting,” refer to the operation instructions for the dental equipment, micromotor and handpiece.
“EMR-interlock endodontic mode” is an operation mode capable of root canal enlargement/preparation in conjunction with the
apex locator. In conjunction with the apex locator, this mode has an automatic rotation control function to prevent the micromotor
from penetrating the apex (apical action) as well as a delicate rotation control function (OGP/OTR). For using this mode, the
equipment should meet all of the following operational requirements:
For details on how to handle the micromotor and handpiece, be sure to read the separate operation instructions and medical
device package insert.

* Shows functions available only when the chair unit has the root canal length
measurement function.
** Only constant speed mode is available when the rotational motion is set to torque
reverse.
***These functions can be changed by setting each memory, but the default is set to OFF.
Unit:
The root canal length measurement function is incorporated.
Micromotor:
TR-S3-R-O (Torx model with light and compatible with root canal
length measurement)
Handpiece:
CA-10RC-ENDO (Torqtech speed-down contra angle model for
endodontic treatment)

Operational requirements of EMR-Interlock endodontic mode
• The EMR-interlock endodontic mode is
not automatically recognized. Be sure
to con
fi
rm that the equipment meets all
operational requirements.
