Product function and usage

Scaling function

Usage

• Open the packing box, make sure that all the parts and accessories are complete according to the packing list. Take the main unit out of the box and put it on a stable plane.
• Turn the water control switch to the max based on symbol as shown as 3.5.2[note 1].
• Insert the plug of the foot switch to its socket(picture 2).
• Connect one end of the water line to the water entrance, and the other end to the pure water source(picture 3).
• Screw the scaling tip tightly to handpiece by torque wrench, then connect the handpiece and the connector of cable correctly.
• Insert the plug of the power source to its socket ,then get through to the electricity (picture 2).
• Switch on the main unit, then the scaling indicator and the first five lights of power regulator shine.
• Select a suitable scaling tip as you need, screw it on the handpiece tightly by the torque wrench(picture 5).
• The normal frequency is extremely high. Under the normal working state of scaling tips , a light touch and a certain to-and-fro motion will eliminate the tartar without heating. Overexertion and long-time lingering are forbidden.
• Vibrating intensity: Adjust the vibration intensity as you need, generally turn the knob to the middle grade. According to patients’ different sensitivity and the rigidity of the gingival tartar, adjust the vibration intensity during the clinical treatment.
• Water volume adjust: Step on the foot switch, and the tip begins to vibrate, then turn the water control switch to form fine spray to cool down the handpiece and clean the teeth.
• The handpiece can be handled in the same gesture as a pen in hand.
• During the clinical treatment, be sure not to make the end of tip touch the teeth vertically and not to make the tip overexert on the surface of the teeth in case of hurting the teeth and damaging the tip.
• After finishing operation, keep the machine working for 30 seconds on the water supply condition in order to clean the handpiece and the scaling tip.
• Unscrew the scaling tip and pull out handpiece, then sterilize them.

Notice

• Don’t pull out the handpiece when the foot switch is stepped on and the machine is vibrating.

Instruction for main components of detachable handpiece (showed in picture 4)：

• Nipple: The nipple can be removed. You can screw out the nipple and clean the pole with alcohol termly.
• Handpiece seal：The seal can be removed and cleaned with alcohol termly.
• Handpiece: The main part of the whole handpiece, can be autoclaved under the high temperature and pressure.
• The connector of the cable：Connect the handpiece with the water source and power supply of the main unit.

Notice

• Keep dry when the detachable handpiece connect to the connector of the cable.

2.1.3 Torque wrench use instruction (showed in picture 5)

• The torque wrench’s structure is designed in special way which can control the strength of the scaling tip’s installation properly and correctly. It also can guarantee the operator screw or unscrew the scaling tip effectively and keep their hands away from being scratched.

Operation

1. Take the scaling tip into the torque wrench; operate as showed in picture 5.
2. Tip installation: Hold the handpiece turn the tip toward direction as showed In picture 5 with the torque wrench. Turn two more circles when the tip stops, then the tip is installed.
3. Tip uninstallation: Hold the handpiece, turn the wrench toward anti-clockwise direction.
4. Sterilize it in sterilizer after each treatment.
5. The torque wrench must be cooled naturally after sterilization to avoid scald when using next time.
6. Keep the torque wrench in a cool, dry and ventilated place and be clean.

Precaution

The following sterilizing methods are forbidden.

1. Braise in liquor;
2. Dip in iodine,alcohol or glutaraldehyde;
3. Torrefy in oven or microwave oven.

Notice

• We are not responsible for any damage of the torque wrench directly or indirectly made by any way in the above items.

Endo function

• Usage process
  1. Fix endochuck to handpiece by endo wrench.
  2. Unscrew the screw cap on the endochuck.

  6. When ultrasonic scaler turns into endo function, only the first lead light is on and the power is at 1st grade. Put the ultrasonic file into the patient’s root canal slowly, step on the foot switch, then make endo treatment. During the treatment, turn up the power gradually according to the needs.
• Notice
  1. When fixing endochuck, it must be screwed down.
  2. The screw on the endochuck must be screwed down.
  3. Don’t press it too much when the ultrasonic file in root canal.
  4. Don’t start up the foot switch until the ultrasonic file is in root canal.
  5. The power range is supposed from 1st to 5th grades.

Sterilization And Maintenance

Sterilization of detachable handpiece

Autoclaved in high temperature/pressure:

• 1210C/1bar(0.1MPa), 20 minutes
• 1350C/2.2bar (0.22MPa), 18minutes
• Pull out the handpiece and unscrew scaling tip and endochuck after each operating.
• Pack the handpiece with sterile gauze or sterile bag before sterilizing.
• Reuse handpiece after it cools naturally in case of burning hand.

Notice

• Clear the cleaning liquid on the handpiece with compressed air before sterilization.
• Be sure that the scaling tip has been unscrewed from the handpiece and it cannot be sterilized with others.
• Please notice whether the outer of the handpiece is damaged during the treatment or sterilization, don’t smear any protective oil on the surface of handpiece.
• There are two waterproof “o” rings at the end of handpiece. Please lubricate them with dental lube frequently, as sterilization and repeated pulling and inserting will reduce their using life. Change a new one once it is damaged or worn excessively.
• The following sterilizing methods are forbidden:
  1. Put handpiece into any liquid for boiling.
  2. Dip handpiece in disinfectors such as iodine, alcohol and glutaraldehyde.
  3. Put handpiece into oven or microwave oven for baking.

Sterilization of scaling tips and endochuck

• All the scaling tips and endochuck can be disinfected with alcohol cotton or disinfected cloth. It’s also ok to disinfect them by ultrasonic cleaner.

Sterilization of torque wrench and endo wrench

• The torque wrench and endo wrench can be disinfected by neutral noncorrosive disinfector for cleaning and sterilizing, or be sterilized in high temperature and pressure.
• The following sterilization ways for torque wrench are forbidden:
  1. Braise in liquor;
  2. Dip in iodine, alcohol or glutaraldehyde;
  3. Torrefy in oven or microwave oven.

Notice

• We are not responsible for any damage of the torque wrench directly or indirectly made by any way in the above items.

Recommended separation distances between portable and mobile RF communications equipment and the model UDS-A

The model UDS-A is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the model UDS-A can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the model UDS-A as recommended below, according to the maximum output power of the communications equipment.

Rated maximum output power of the transmitter

| Separation distance according to frequency of transmitter

m

150kHz to 80MHz d=1.2×P1/2| 80MHz to 800MHz d=1.2×P1/2| 800MHz to 2,5GHz d=2.3×P1/2

100| 12| 12| 23
For transmitters rated at a maximum output power not listed above, the recommended separation distanced in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) accordable to the transmitter manufacturer.

NOTE 1: At 80 MHz and 800 MHz. the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

The device has been tested and homologated in accordance with EN 60601-1-2 for EMC. This does not guarantee in any way that this device will not be effected by electromagnetic interference.
Avoid using the device in high electromagnetic environment.
