Thank you for purchasing the NSK iCare. Please read this Operation Manual carefully before use to become familiar with operation instructions and care & maintenance. Keep this Operation Manual for future reference.

• TO PREVENT ELECTRIC SHOCK, use a main electrical outlet that is earthed. • Be careful not to get water or liquid disinfectant or maintenance oil on the Unit. This could cause short circuits and lead to fire and/or electric shock. • Excessively turning the Main Power Switch ON and OFF may blow a fuse. • When installing the product, provide space of approximately 10cm around the product for easy access to the inlet and the Power Cord. • For safety, install the Unit in a place where the AC power cord can be easily removed. CAUTION • Read this Operation Manual before use to fully understand the product functions and file for future reference. • Do not use iCare to lubricate air scalers (except for NSK Ti-Max S970 series) and Phatelus air motors. The iCare lubricating system is not designed to lubricate those particular products. Maintain air scalers and Phatelus air motors as described in the operation manual for each product. • If blood infiltrates inside a handpiece, iCare may not totally lubricate the internal handpiece components, and internal blood coagulation may cause product failure. In this case, NSK recommends to immediately lubricate those handpieces with PANA SPRAY Plus. • Autoclave handpieces AFTER lubricating with this product. • Place a collector such as a tray under the Unit. • After use, turn off the Power Switch and shut off the air supply (Air Compressor). • Drain water from the Air Compressor and Air Filter at least once a week as required. Moisture from the tank could mix with the Maintenance Oil and defeat the purpose of this device. • Remove the Air Tube and the AC power cord from the Unit if the Unit is not to be used for a long time. • Do not store the Maintenance Oil in contact with halogen, strong acid, alkali, and oxidizing substance or in the same place as these substances. • Use only consumable parts such as maintenance oil, and accessories such as an AC power cord specified by NSK. Other than what we specify may cause product failure due to insufficient lubrication. • This device is for indoor use only. • Keep the Unit on a level surface. • Do not attempt to disassemble the product or tamper with the mechanism except as recommended by NSK in this Operation Manual. • Do not allow any impact on to the product. Do not drop the product. • Should the product function abnormally, cease operation immediately and contact your Authorized NSK Dealer. • Perform regular function and maintenance checks. • If the product is not used for a long period check it is functioning correctly before use. • Installation and use of this product requires special precautions regarding EMC according to the EMC information. • Portable and mobile RF communications equipment can affect Medical Electrical equipment. Do not use RF equipment near the product. • The use of ACCESSORIES such as cables, other than those specified by the manufacturer, with the exception of cables sold by the manufacturer of this product as replacement parts for internal components, may result in increased EMISSIONS or decreased IMMUNITY of this product. • This product should not be used adjacent to, or stacked with, other equipment. If adjacent or stacked use is necessary, this product should be observed to verify normal operation in the configuration in which it will be used. • The system may present a possibility of malfunction when used in the presence of an electromagnetic interference wave. Do not install the system in the vicinity of any device which emits magnetic waves. Turn off the Main Power Switch of the system as an ultrasonic oscillation device or an electrode knife is located close to the vicinity of use. • U.S. Federal law restricts this device to sale by or on the order of a licensed physician. NOTICE • No special training is required for this device. • This product is not intended to perform a hygienic cleaning of the internal parts of the handpiece.

Electromagnetic environment - guidance

RF emissions CISPR11/EN55011

Group 1

The product uses RF energy only for its internal function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.

RF emissions CISPR11/EN55011

Class B

Harmonic emissions EN/IEC61000-3-2

Class A

The product is suitable for use in all establishments, including domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes.

Mains power quality should be that of a typical commercial or hospital environment. If the user of the product requires continued operation during power mains interruptions, it is recommended that the product be powered from an uninterruptible power supply or a battery.

Power frequency (50/60Hz) magnetic field EN/IEC61000-4-8

30A/m

Power frequency magnetic fields should be at levels characteristic of a typical location in a typical commercial or hospital environment.

NOTE: 'Ut' is the AC mains voltage prior to application of the test level. *: eg: "25/30 a cycles" means "25 cycles for a 50Hz test", or "30 cycles for a 60Hz test".

Conducted RF EN/IEC61000-4-6

3Vrms 150kHz to 80MHz

Radiated RF EN/IEC61000-4-3

10V/m 80MHz to 1.0GHz

Portable and mobile RF communications equipment should be used no closer to any part of the product, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.

3V/m 1.4GHz to 2.0GHz

1V/m 2.0GHz to 2.7GHz

Recommended separation distance d = 1.2 P d = 0.35 P 80MHz to 800MHz d = 0.70 P 800MHz to 1.0GHz d = 2.3 P 1.4GHz to 2.0GHz d = 7.0 P 2.0GHz to 2.5GHz Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer, and (d ) is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters as determined by an electromagnetic site survey(a) should be less than the compliance level in each frequency range(b). Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE1: At 80MHz and 800MHz, the higher frequency range applies. NOTE2: 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 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 fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the product is used exceeds the applicable RF compliance level stated above, the product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the product. b: Over the frequency range 150kHz to 80MHz, the field strength should be less than 3V/m.
