• Make certain there is a match between incoming power

supply and the product electrical requirement. Do not use
the recharger with voltages diff erent 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 fi re 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 fi re or in direct sunlight, etc.

• Store the unit away from fl ammable materials.
• If the lithium-polymer battery should leak, do not touch

the liquid. In case of skin contact, fl ush 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 fi x 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 fi x 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

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
affi x 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

• LED powered visible light curing and visualisation unit

with high power output

• The D-Light Pro can polymerize light cured dental

materials, quickly and effi ciently.

• The D-Light Pro contains two diff erent types of LEDs

with diff erent wavelength peaks. This enables the
D-Light Pro to activate commonly used photo initiators
used in dentistry, like Camphorquinone (wavelength
peak of 468 nm) used in most light-cured materials, and
other initiators (wavelength peak of 400 +1-20 nm)
used in some light-cured dental materials.

• The D-Light Pro Detection mode (DT) assists the

visualisation of bacteria in plaque and carious lesions
and the identifi cation of fl uorescent materials.

• The D-Light Pro off ers an easy-to-use and elegant

stainless steel design. The design ensures a
user-friendly operation of the unit.

• Lithium polymer batteries, when fully charged, allow

for more than 45 individual irradiations of 20 seconds
duration each. The lithium polymer battery has no
memory eff ect, and a fast recharging speed of 75
minutes.

• The D-Light Pro is designed to off er a stable and

continuous high light output over several years.

• Built-in radiometer
• In addition to the light guide, the handpiece is

autoclavable once the internal electronic module and
battery pack have been removed.

• The D-Light Pro is under warranty for a period of 3

years, except the battery (1 year warranty) and
consumables (no warranty).

3. INDICATIONS

• Polymerisation of visible light curing materials curing

with a wavelength range of 400 to 480nm. In case of
questions about the wavelength ranges for certain
materials, please contact their respective
manufacturers.

• The Detection mode (DT) assists the visualization of

bacteria in plaque, fi ssures, infected dentin and the
presence of micro-leakage. It also helps to identify
fl uorescent restorative materials, and to evaluate the
depth of cracks in the tooth structure.

Battery

• Prior to initial use or use after a long interval of non-use,

be sure to charge or recharge the batteries completely.
Use the original charging station and lithium polymer
battery only. Do not use any other battery chargers or
batteries.

• Connect the power cord to the charging station, and the

plug of the power cord to the mains power outlet
(110-240V AC) (Figure 8)

• Insert the batteries fully onto the docking ports of the

charging station until you hear/feel a ‘click’ (Figure 9)

• There is a LED corresponding to each docking port.

When the LED is illuminated, the battery is in the process
of being charged. When the LED turns off , then charging
is completed. Two batteries can be simultaneously
charged.

• Do not connect the depleted battery pack to the

charging station until it is properly cleaned and
disinfected.

• The time to fully charge an empty battery is

approximately 75 minutes.

• When the D-Light Pro is not in use for a prolonged

period of time, the battery pack should be disconnected
from the handpiece; or the handpiece/battery should be
in the “off ” position.

• Batteries may be stored on the docking ports of the

charging station as long as there is power to the
charging station.
