· This product needs special precautions regarding EMC and needs to be installed and put into service according to the

EMC information.

· Portable and mobile RF communications equipment can affect this product.

· The use of ACCESSORIES, transducers and cables other than those speciﬁed, with the exception of transducers and

cables sold by the manufacturer of the product as replacement parts for internal components, may result in increased

EMISSIONS or decreased IMMUNITY of it.

· This product should not be used adjacent to or stacked with other equipment and that if adjacent or stacked use is

necessary, it should be observed to verify normal operation in the conﬁguration in which it will be used.

· Use an electrical outlet that is grounded. It may cause electrical shock, if it may not use it.

· When operating the handpiece always consider the safety of the patient.

· The handpiece is designed only for dental clinical use.

· Check the vibration outside the patient´s oral cavity before use. If any abnormalities are found, stop using immediately

and contact your dealer.

· Should this product function abnormally, cease operation immediately and returen it to the dealer for repair.

· Do not force or pull on Power Cord and/or Handpiece Cord. It could cause disconnection.

· Do not exceed Maximum Power Level for Tips. It could damage tooth structure and Tips.

· Check if the Tip has no ﬂush, damages, bending and rust before use. Use new one.

· Always use with pouring enough water, or it may damage tooth plane and overheat the handpiece.

· Do not hit metal or prosthetic crown etc., except for removing them. Tips could break and fall into mouth.

· Do not sharpen and/or bend the Tip. Tips may damage and not generate enough vibration during scaling.

· Do not hit gingiva, mucosa and/or skin directly. It could cause damage and burn.

· During cutting, Tip will gradually wear away, as the Tip wears the stroke will get smaller and cutting power level will

decrease. When level drops too far, change the Tip.

· Be sure to ﬁrmly mount the Tip with provided Wrench, or the Tip will not generate enough vibration.

· Check to see if dust does not stick on the screw of the Tip before use. If not clean, Tips will not generate enough vibration.

· Be sure to turn the Power Switch after mounting the handpiece.

· Be sure to attach NSK genuine Tips when using NSK Varios Ultrasonic Scaler (Varios 750 or Varios 750 LUX) The

problems such as damage, failure and accident of Handpieces resulting from use of Non-NSK Tips are not included in the

· Remove the handpiece after Tip is taken off.

· Do not put liquid such as high acid water in the bottle.

· Implant maintenance scaler tips should be inspected for proper resin coating prior to use and any possible exposure of

the metal core to a dental implant should warrant replacement of the scaler tip.

CAUTION

· During vibration, the handpiece and the handpiece cord may affect computer and LAN cable. Noise could be heard during

operation near a radio receiver.

· Be sure to turn off the Power Switch after use. Remove the power plug and water inside of the control unit if not used for

a long time.

· Users are responsible for operational control, maintenance and inspection.

Clean periodontal pocket at low power. (Set

the level less than “ 2”.)

Carefully insert the

scaler Tip into the

Tip Cover S. Avoid

injuring the ﬁngers.

WARNING

Do not use the Tip Cover S as a Tip change tool.

CAUTION

How to use the Tip Card

1) Place the neck of the Tip in the cut out.

2) Check wear of the Tip.

3) See the green, yellow and red line to check wear of the Tip. *See below what each color means. At NSK we recommend

to replace a Tip when the Tip meets the yellow line (wear of 1mm) to guarantee safe and effective use.

Green: No wear - Tip is OK

Tip replacement is not necessary.

Yellow: Wear of 1mm - Tip is showing some wear

Tip replacement is recommended.

Red: Wear of 2mm - Tip is badly worn

Tip replacement is necessary.

Tips are consumables. The efﬁciency of dental scaling

decreases approximately 25% when the top of the Tip

wears 1 mm and approximately 50% when it wears 2 mm.

In addition, the vibration condition changes owing to the

wear, which may damage a patient’s tooth surface. Check

the Tip wear condition with the Tip Card periodically, and

replace the Tip with a new one in good time.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reﬂection from structures, objects and people.

a Field strengths from ﬁxed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobiles radios, amateur radio, AM and FM radio

broadcast and TV broadcast cannot be predicted theoretically with accuracy.To assess the electromagnetic environment due to ﬁxed RF transmitters, an

electromagnetic site survey should be considered. If the measured ﬁeld strength in the location in which the Varios750 / Varios750LUX is used exceeds the

applicable RF compliance level above, the Varios750 / Varios750LUX should be observed to verity normal operation. If abnormal performance is observed,

additional measures may be necessary, such as reorienting or relocating the Varios750 / Varios750LUX.

b Over the frequency range 150kHz to 80MHz, ﬁeld strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the Varios750 / Varios750LUX.

The Varios750 / Varios750LUX is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the

Varios750 / Varios750LUX can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications

equipment (transmitters) and the Varios750 / Varios750LUX as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d 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) according to the transmitter manufacturer.
