• Make certain there is a match between incoming power
supply and the product electrical requirement. Do not use
the recharger with voltages different than stated in this
manual or labeled on the equipment.
• Do not touch the inside of the battery compartment or
the contact points of the battery charger directly with the
hands or any metal objects. This may cause a breakdown.
• The battery should not be thrown into a fire or heated. It
should not be struck with a sharp object or with force,
disassembled or remodeled. This may cause the battery to
leak, generate heat, ignite or explode.
• Do not allow the battery contact points to touch other
metal objects. Do not carry or store the battery next to
metal objects in order to avoid accidental contact with the
battery contact points.
• Do not charge, use or leave the battery in high
temperatures, near fire or in direct sunlight, etc.
• Store the unit away from flammable materials.
• If the lithium-polymer battery should leak, do not touch
the liquid. In case of skin contact, flush immediately with
tap water because the liquid may be corrosive and cause
skin irritation or damage.
• If any liquid leaks from the battery and comes into contact
with the eyes, do not rub. Flush immediately with tap
water and seek medical attention. The liquid may cause
eye irritation or damage.
• Voltage is present in the charging station and battery
packs: do not open! Operate only in dry conditions. Never
manipulate with wet hands as this may cause an electrical
shock.
• If the battery or unit should begin to smoke, emit a bad
odour, deform or discolor during irradiation, charging or
storage, then discontinue usage immediately. Continued
usage may cause the battery to leak, and/or the unit to
generate heat, ignite or explode.
• Avoid sudden or strong impacts to the handpiece. This
may cause a breakdown or a reduction in the amount of
light emitted.
• Do not use mobile phones or other hand-held electronic
devices at the same time as the D-Light Pro.
• The light guide and eye-protection shield (either hard or
soft version) should be attached correctly in order to
ensure that they do not become detached during use.
Check routinely. Should they become loose or cracked,
then discontinue their use to avoid hazards such as
swallowing or inhalation. Make sure to fix the eye-
protection shield correctly.
• If the light guide should crack or break, immediately
discontinue use. The light guide is made of glass and there
is a possibility of fragments accidentally being displaced
into the mouth.
• Do not look directly into the light emitted through the
light guide. This may cause eye damage. Prior to use, be
sure to fix the eye-protection shield (either hard or soft
version).
• Prolonged usage of any curing light can increase
temperature. Extended usage near pulp and soft tissues
should be avoided to prevent injury. Curing near or around
sensitive tissues should be performed in short time
DLIGHT® PRO
DUAL WAVELENGTH LED CURING LIGHT
intervals. The Low Power mode (LP) can also be used to
limit heat generation when close to the pulp.
• If the handpiece is not used for an extended period of
time, or the unit is being transported, then the battery
should be removed from the handpiece or charging
station.
• Maintain adequate infection control measures when using
the D-Light Pro in the oral cavity, and execute the
appropriate hygiene plan after usage with patients.
• Protect the D-Light Pro from contamination by using
protective plastic barrier-sleeves. These sleeves are
intended for single-use; discard after each patient to
prevent possible cross-contamination. Protective plastic
barrier-sleeves are not needed when the light-guide and
handpiece sleeve are autoclaved between each patient.
• When using protective plastic barriers (bags, shields, etc.)
with the D-Light Pro, be certain that these are securely
affix to avoid patient aspiration and treatment
complications.
• Do not use the Detection mode (DT) in conjunction with
caries detection dyes.
• Do not use if you have red-green color blindness or visual
impairment.
2. FEATURES
