OLED display a) Customized program sequence number 1-9, totally 9 programs b) Operation mode c) Battery consumption d) Set speed e) Set torque f) File system g) Operation mode h) Torque setting i) Real-time torque Protective function of automatic reverse During operation, if the load value exceeds the preset torque value, the file rotation mode will automatically change to Reverse Mode. And the file would return to normal rotation mode when the load is below the preset torque value again. a) Clockwise rotation: Load value is lower than preset torque value b) Counterclockwise rotation: Load value is higher than preset torque value. c) Clockwise rotation: Load value is lower than preset torque value again. INDICATION: The device is suitable for shaping the root canals during root canal treatment & an advantage in replacing the hand files to rotary endodontics. CONTRAINDICATION: Patients with implanted pacemakers (or other electrical equipment).
