PRODUCT SAFETY WARNINGS AND CAUTIONS
Consistent function and safe operation of this curing light system is dependent on the user's compliance with
the following safety procedures as well as the specific safety comments and recommendations presented
throughout these Instructions for Use. Users must be qualified medical professionals.
WARNINGS
The Demi Ultra Curing Light is an electric device designed to meet worldwide electrical safety
standards, including U.S., Canada, and Europe, to be safe and effective for all dental
applications. To avoid electric shock:
• Do not attempt to open or alter the unit in any way. Only service centers authorized by Kerr
Corporation may open the unit housing and repair the device.
• Do not introduce any foreign objects into the housing of the unit.
• Use only the Demi Ultra charging dock when recharging this product. Never attempt to use
any other device for recharging.
• Connect the power plug into a suitably grounded and approved outlet. If using an extension
cable, make sure that the ground line is not interrupted.
• Always unplug the charging dock before disinfecting.
• Never use the power supply cord if damaged.
The Demi Ultra Curing Light produces high-output curing energy. Prolonged exposure to the
eyes, exposed skin, oral mucosa, or tissues near the pulp can result in irritation or injury. It is
important to observe the following precautions and procedures:
• Positioning: When curing, position the LED Light Attachment tip directly over the cure
material. Do not place light directly on or toward unprotected gingiva or skin.
• Eye exposure: Do not look directly at the light emitted from this curing unit. Do not
operate this device without suitable eye protection for the operator, assistant, and patient.
Select eye protection that filters blue-violet and ultraviolet light. Securely attach Light
Shield before each use. Avoid prolonged exposure of unprotected eyes to light scatter or
reflected light. If light exposure causes blurring/starring of vision or visual after-image that
persists, consult a physician.
• Skin exposure: Avoid prolonged exposure to skin. If skin rash, sensitization or other
reaction occurs, discontinue use and seek medical attention.
• Oral mucosa exposure: Avoid prolonged exposure to oral soft tissues. Prolonged exposure
may cause soft tissue irritation or burns. Most minor reactions require only thorough
cleansing and palliative treatment. If irritation persists, seek medical attention.
• Continuous operation of the curing light by performing repeated and sequential curing
cycles can lead to device overheating. This excessive heat and radiation can result in damage
to pulp and soft tissue when contacted or in close proximity to the LED Light Attachment.
Exposure times given in these instructions must be observed to avoid any such damage.
If a longer cure is needed, perform polymerization at intermittent intervals.
