5
C, it will automatically return to the previously set grade.

3.2 Ultrasonic system
3.2.1 Scaling
1) Turn on the power switch and pick up the ultrasonic
handpiece, afterwards the panel will automatically shift
to Ultrasonic mode.
2) Press the G button to enter Scaling mode.
3) Select the tip and tighten it on the handpiece by
torque wrench.
4) When stepping on the button A, tip vibrates with LED
on and water emits; Release the button, vibration and water stop, LED will be off 10 seconds later.
5) The handpiece is generally held in a pen-holding position.
6) The frequency is extremely high when the machine is on working. It can remove the tartar with the tips softly stroke on the teeth
surface like erasing motion. DO NOT stay long or put overmuch pressure on the teeth.
7) Vibrating intensity: Adjust the vibrating intensity according to your need. The setting power is level 3, please adjust the vibrating
intensity according to the teeth sensitivity and hardness of calculus during clinical application.
8) Water volume: Please adjust the volume on the panel.
9) During clinical scaling, please keep the side of the tip adapt to the tooth surface horizontally, with light lateral pressure to allow the
tip vibrate freely.
10) After operation, please keep device working for 30s with water to flush the handpiece and tips; Remove the tip and get it sterilized.
3.2.2 Periodontal treatment
1) Use a torque wrench to tighten the periodontal treatment tip to the ultrasonic handpiece. Click the P button on panel to enter the
periodontal treatment mode.
2) The operation and adjustment methods are similar to Scaling mode.
3.2.3 Endodontic irrigation
1) Tighten the endo file to the handpiece by endo wrench.
2) Click on the E button and enter the Endo mode.
3) The default power is level 1 under Endo mode, operator can adjust the power according to the need in clinical treatment.
4) Select the appropriate Endo file and slowly place it into the root canal of the patients teeth. Step on the foot pedal to start
ultrasonic endodontic irrigation.
5) During clinical cleansing, the file should not be pressed too tightly when it is in the root canal
6) Do not step on the pedal before the file is in the root canal.
7) The suggested power range for endodontic irrigation is level 1-level 5.
3.3 Air polishing system
1) Add appropriate amount of powder to the powder tank (the amount of powder added should be between "Max" and "Min" marked
on the the tank), then tighten the upper cover of the powder tank, and fix the powder tank on the main unit.
2) Pick up the Air polishing handpiece, afterwards the panel will automatically shift to Air polishing mode.
3) Adjust the water volume and air pressure, aim the nozzle at a pool, press the foot button A, and confirm that the nozzle can spray
gas, powder and water spray normally before use.
4) Before Air polishing treatment, please wear goggles and veil on the face of the patient. Users should wear goggles or a protective
mask.
5) The handpiece is generally held in a pen-holding position.
6) Adjust the water volume and air pressure to an appropriate level. The recommended water volume starts at level 5 and the air
pressure starts at level 3. According to the sensitivity of the patient's teeth and hardness of the dental plaque, adjust the water
volume and air pressure at any time during the clinical process; increasing the air pressure will enhance cleaning effect, but will
weaken the polishing effect; increasing the amount of water will enhance the polishing effect, but will weaken the cleaning effect.
7) The nozzle should be aligned with the tooth surface during the cleansing, but avoid direct contact. Keep the nozzle and the tooth
surface at a distance of 3-5mm at 30-60 angle. The smaller the angle, the larger the cleaning area; during the cleansing, please
Perform a small circular motion on the surface of the tooth.
8) The air/powder mixture reflected from the tooth surface should be evacuated by using a strong suction device on the dental unit
during treatment.
9) After treatment, adjust the water volume to the maximum level, and polish the surface of teeth.
3. 4 Cleaning Mode
It is recommended to flush and disinfect the pipeline of the device every day. "Cleaning" mode allows cleaning and disinfection of the
pipeline to reduce the accumulation of crystals and the number of bacteria in the pipeline.
1) Fill a water bottle with distilled water or demineralized water.
2) Pick up the ultrasonic handpiece, point the handpiece at the sink, click the Cleaning button on the screen, and press the button D
on foot pedal to start cleaning the pipeline. Then, the pedal can be released.
3) After cleaning for 30 seconds, the device will automatically stop the Cleaning mode. You can also press the button D on foot pedal
again in the Cleaning mode or click Purge on the screen to stop cleaning.
4) After cleaning, put the ultrasonic handpiece back into the bracket. And then, pick up the air polishing handpiece, point the
handpiece nozzle at the pool, and click the Cleaning button again, so that the device will automatically blow out the residual powder
in the pipeline and release the high pressure gas in powder tank.
5) After cleaning for 20 seconds, the device will automatically exit the Cleaning mode. You can also click Purge on the screen to stop
cleaning.
3.5 Setting
1) Click "ON" /"OFF" to turn on or off the heating function. (According to the actual water output, the water temperature is different).
2) Click the "Settings" button at the bottom right corner of the screen to enter the "System Settings" interface
3) Click Calibration button, the system will automatically calibrate the air pressure to the value set in the program
4) The Bluetooth pedal has been matched to the machine, any subsequent replacement of foot pedal or main unit needs to make
new pair.
