Safety Precautions
WARNING: If you neglect these safety precautions, you may cause personal injury such as electric shock, re or
damage to the product.
1.Use a separate, grounded power outlet. Never use wet hands to unplug the power cord.
2.Please put the power plug into the socket easy to pull out, to make sure it can be pulled out in emergency. Please do not use
other than the specied voltage.
3.Do not damage, modify, pull, over bend or twist the power cord, do not place heavy objects on the power cord.
4.Do not place the product on unstable workbenches, such as shaky tables, bevels, or vibrations.
5.Keep the scaler clean before and after operation. The scaling tip, wrench and handpiece (detachable) must be sterilized before
each treatment.
6.The tip must be tightened to the handpiece with torque wrench. While scaler is working, the heat of scaling tip may become
higher if there is no water owing out, make sure the irrigation is good.
7.Don't twist or rub the tip. Change a new one when the tip is damaged or worn excessively.
8.Don't screw the scaling tip while stepping on the foot switch.
9.Don't use impure water source, and be sure not to use normal brine instead of pure water source.
10.If use the water source without hydraulic pressure, the water surface should be one meter higher than the head of the patient.
11.Don't knock or rub the handpiece. Do not pull the cable while the device is working, to avoid damage to the cable.
12.After operating, turn o󰀨 electrical source, and then pull out the plug.
13.The screw thread of the scaling tips produced by other manufacturers is maybe coarse, rusty and collapsed, which will
damage the screw thread of the handpiece irretrievably. Please use our scaling tip.
14.This equipment is only applicable to the corresponding type of power adapter produced by our company.

Field strengths from xed RF transmitters, as determined by an electromagnetic site
survey,ashould be less than the compliance level in each frequency range.b
Interference may occur In the vicinity of equipment marked with the following
symbol:
NOTE 1 At 80 MHz end 800 MHz. the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is a󰀨ected by absorption and reection from structures,
objects and people.
a Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey should be
considered. If the measured eld strength in the location in which the Ultrasonic scaler are used exceeds the applicable RF compliance level
above, the model Ultrasonic scaler should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Ultrasonic scaler.
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3V/m.

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