Installation and Connection
- The adaptor should be disconnected from the charger before connecting the power cable
to prevent an electric shock.
- Keep away from sources of ignition to avoid fire or explosion.
- Protect the handpiece, charger, and battery from any liquid to avoid electric shock or
functional error.
- Place the charger on a flat and stable surface. Do not drop handpiece or charger in order to
avoid internal defect that may cause overheating or fire.
- Do not place the electrical cord near a gas burner or sources of heat.
Should the cord catch on fire, replace with a new one to avoid short-circuit.
- Do not use or leave the unit in areas of high temperature or exposed to direct sunlight;
internal circuit defect may cause overheating or fire.
- Securely connect the dust-free power plug to the outlet.
Use this device in well ventilated areas. Overheating may cause fire.
- Do not touch the terminal areas of charger or battery with fingers or conductive objects,
such as metal wire or safety-pin. It may cause electric shock or fire.
- Do not use any charger other than supplied. It may result in electric shock or fire.
- Do not plug the power cord with wet hands. This may result in an electric shock.
- In case of fluid leak from battery or partial discoloration/deformation of the handpiece,
immediately discontinue use.
- Place the battery in correct direction when charging. Wrong directed placement may
cause malfunction, explosion, or fire.
- In case of partial discoloration of the charger, immediately disconnect the power plug
and repair the charger.
- In case battery fluid contacts the eye, immediately flush with copious amount of clean
water and seek medical attention.
- Do not use this product on patients with a history of cataract, retinal damage or allergic
reaction to light.
- Do not use this product on a person with a pacemaker as it may cause malfunction of
the pacemaker.
- Avoid exposing the light on intraoral soft tissue as it may affect the soft tissue.
- Do not put the battery on the charger upside down. This may cause an explosion or fire.
- Disconnect the power cord by grasping the power plug to avoid injuries or burns.
- Avoid damage or use of unnecessary force on the power cord. This may cause an electric
shock or fire.
- Should battery fluid contact the skin or clothes, immediately wash it off with copious
amounts of water to avoid skin damage.
- Take the battery out of the handpice if it won't be used for more than 1 week.
- Connect the power plug only when battery is being charged. Insulation degradation may
cause electric shock or fire.
- Do not use this product for any purposes other than dental use.
- Use only the battery supplied to avoid fluid leak or explosion.
- Never disassemble or overhaul the product. Unusual performance may cause injuries,
electric shock, or fire.
- Ensure that charger and battery are always separated from the handpiece prior to cleaning.
- If the OLED screen malfunctions, remove the battery from the handpiece and reinsert it.
