Product Safety Warnings and Cautions
Prior to installation and activation of the light, please read these instructions carefully and follow safety
procedures as well as the specific safety comments and recommendations presented throughout the
instructions for use. The manufacturer accepts no liability for any damage resulting from the improper use of
this unit and/or for any purpose other than those covered by these instructions.
1. CAUTION! FUSION lights produce high intensity light. Prolonged exposure to the skin, oral mucosa, or pulp
can result in irritation or injury.
-Do not place light in direct contact with unprotected gingival, oral mucous membrane or skin.
-Do not place light directly on the same tooth segment for more than 6 seconds in Plasma Power Mode.
-If long exposure cannot be avoided, direct a stream of air over the tooth surface from an air syringe or
high-speed vacuum tip, adjust to Pulse Power Mode or adjust curing distance.
2. CAUTION! Do not look directly at light emitted from the device. Do not use FUSION lights without suitable
eye protection for the operator, assistant and patient. Use Light Shield, Protective Goggles, and/or Curing Caps.
Exposure must be restricted to the area of the oral cavity for which the clinical treatment is intended.
3. CAUTION! FUSION must be used with “Single Use” Barrier Sleeves to avoid cross contamination.
Replace Barrier Sleeve after each patient treatment is completed. This sleeve also prevents composite/residue
material from adhering to the surface of the lens and degrading the curing performance.
4. Products marked “Single Use” on the labeling are intended for single use only. Discard properly after each use.
5. DO NOT operate the unit in the proximity of flammable mixtures. Use in well-ventilated area.
6. Keep solvents, flammable liquids, and sources of intense heat away from FUSION as they may damage internal
and external parts, the seals or the buttons on the control panel.
7. DO NOT autoclave or immerse the unit in any kind of ultrasonic bath, disinfectant, cleaning solution or any kind of
liquid. Do not spray liquids directly onto the light and prevent liquids from entering FUSION open area such as
Keypad, Charging Stand and its connectors as this may damage or short-circuit the device and can cause
potential hazard for operator and/or patient.
8. Caution: Federal law restricts this device to sale by or the order of a licensed dentist.

Start Up
Assemble Handpiece
Upon receiving your FUSION,
remove all components from
the package and examine
them. If damage is apparent, please contact your authorized DentLight distributor from whom your light was purchased.
Attach the Battery Assembly to the Main Control by screwing the Battery Assembly clockwise into the Main Control. A
short beep upon connection indicates that the light is battery powered and the LCD display should automatically power on.
Adjust the 360º swivel LED Light Head to a comfortable curing position and ensure good connection with the Main Control.
The modular LED Light Head quick connects to Main Control with easy twist Push/Pull. Light is now ready for use.
Operation and Setting
FUSIONs use advanced Metal Keypad and LCD interface. ON/OFF Key starts and stops the light. TM/PW Key sets the
Operation Time and Power Mode. FUSION defaults in Pulse Power Mode (green backlit LCD and flash MODE symbol)
with 5 second timer. Press TM/PW Key to select a Digital Timer of your choice. Press and hold TM/PW Key for 2 seconds
and release to change power to Plasma Power Mode (white backlit LCD with steady MODE symbol) and vice versa.
Plasma Power Mode allows the fastest curing. Pulse Power Mode maintains the peak power and generates the minimum
heat by lowering the average power in half with a 50/50 on and off duty cycle. Built-in settings are shown in the table
below. After starting, Digital Timer counts down and the light makes an audible beep every 5 seconds. Press ON/OFF Key
anytime to stop.

Built-in Self-Protection FUSION has built in self-protection on low
battery and overheats. Low battery is indicated with low Battery Bars
(one or no bars). Low battery triggers one beep a minute ahead of
self-protection shutdown. Light then goes to sleep mode. Overheating
(above 50°C at the light tip) is indicated with a flashing Thermometer
symbol, an audible warning beep together with a red backlit LCD.
Light shuts off when overheat is triggered. The light will be
deactivated until the temperature is restored back below 38°C.

Curing Recommendations
Please follow the method below to check the performance of the device. For specific resin, sealants and bonding materials,
perform a timed curing test outside the mouth using a 3mm washer or hardness disk. Cure from the top for the
recommended time and reverse the disk. Using a sharp instrument, compare the hardness of the disk to the hardness of
the top composite - it should feel exactly the same if well cured. For general guidance, use recommended curing times
below. The time required to cure can then be determined. It is highly recommended to test the device using radiometer
periodically to track the performance of the device. For general guidance, use recommended curing times below. For
reduced heat or shrinkage, use Pulse Power Mode and replace 3sec with 5sec curing times below.

Battery Care
Keep FUSION on the Charging Stand when not in
use. Connect DC Power Plug to Plug Receptor on the
Charging Base. Peel off Stand Sticky Pad and secure
Charging Stand on a table counter for easy one-handed pick up. Alternatively connect DC Power Plug directly to the
back end of the Handpiece to charge and power on the unit. Separate Battery Assembly from Main Control in case of
long-term storage (>2 months).
LCD screen lights green while charging. LCD backlight turns off when fully charged. It is completely safe to have the light
stand on the Charging Stand all the times. Battery Bar displays three full bars when the battery is fully charged. In normal
operation, Battery Bar drops from three to two bars while running and returns to full bar upon completion of a cycle.
BATTERY DISPOSAL: The Battery Assembly contains a Lithium ion (Li-ion) battery. When the battery is at the end
of its life, recycle or dispose it according to national, state and local regulations.
Techniques
Lens Module: Always use disposable Barrier Sleeves to protect lenses from liquid and
composite damages. Replace Lens Module immediately if it: a) has cured resin or
residue; b) is scratched or cloudy. Align and lock flat edge of Lens Tool (optional
accessary) to flat edge of Lens Module. Turn Lens Tool counter-clockwise and unscrew
Lens Module. Replace damaged lens with a new Lens Module by reversing the steps.
Do not overtight the thread and O-rings underneath.
Light Shield or curing cap: Slide in Light Shield from the LED Light Head to the Handpiece into proper position.
Snap on curing cap before barrier sleeve. Light shield and curing cap functions as protective filter to decrease the
blue light exposure for the operator for safe operation as explained in the precautions paragraph.
Tip Size: Tip and beam size can be adjusted by selecting the proper size Curing Caps. For
small cavity treatment, snap on 9mm Curing Cap and anchor light on occlusal or bonding
surface. For temporary bonding, snap on 3mm Curing Cap (Tacking Tip) at the end of the
Lens Module and apply pressure at the center of crown/veneer for best contact. Tack for 1
second then remove excess adhesives before final bonding. For veneer bonding and molar
cavity treatment, snap on 13mm Curing Cap and place light in direct contact. Curing Caps
are for single use only.
Tacking Tip

Cleaning and Disinfecting
−Clean and disinfect Handpiece and Charging Stand with a soft cloth or tissue dampened with cleaning solution
including: Cavicide, Lysol, Isopropyl or Ethyl alcohol and equivalent. Do not spray, soak, or autoclave.
−Use Q-tips to clean lens and electrical contacts by slightly dampening the tip (do not soak) with Isopropyl alcohol.
−Safeguard Handpiece opening area, Metal Keypad, Charging Plug, and Lens Module against liquid and sharp objects
as this may cause electrical short-circuit, permanent optical damage or malfunction.
Configuration/Add-ons
FUSION has interchangeable LED light head allowing users to customize composite curing to their commonly used dental
materials by switching its modular light head. To interchange the LED light head, simply twist and pull out the modular light
