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

Cautions:
• Use this product only as specifically explained in this manual. Any use of this product
inconsistent with these Instructions for Use is at the discretion, and is the sole
responsibility of, the practitioner.
• The Demi Ultra should be operated only with the supplied LED Light Attachment or
CAUTION
other Demi Ultra LED Light Attachments when available. Do not attempt to use this
product with other Demetron light guides. This product's warranty does not cover any
damage resulting from the attempted use with any light guides or light attachments
other than original Demi Ultra LED Light Attachments. There are no user-serviceable
parts inside the curing unit. Do not open or tamper with the curing unit.
• Check the LED Light Attachment for adequate light output before each procedure. Failure
to verify output may allow inadequate curing (see Product Testing section). Only the
Demi Ultra built-in radiometer or a Demetron radiometer (part number 910726) should
be used. Other radiometers may give erroneous output data and cannot be relied upon to
test Demi Ultra output.
• The Demi Ultra should not be used on patients, or by users, fitted with implanted or
external medical devices, such as an implanted heart pacemaker, who have been
cautioned in regard to being exposed to small electrical appliances, such as electrical
shavers, hair dryers, etc. In all such cases, contact the prescribing medical device
practitioner prior to exposing a patient, or user, to the Demi Ultra.
• The System must be maintained in a clean, undamaged condition. An unclean or
damaged unit should not be used. Do not attempt to operate a damaged System until it
has been thoroughly inspected and serviced by qualified service person.
• To prevent cross-contamination, use a disposable plastic sleeve over the LED Light
Attachment during each use. Do not allow contact of restorative materials with lens on
