USER AND SERVICE MANUAL
FUSION CURING LIGHT (2008 RELEASE)
For dental use only!
U.S. Federal Law restricts this device to sale by or on the order of a licensed dentist
Made in USA
Curing Times
1. Normal composite resin (2mm A3 or lighter): 5 seconds.
2. Orthodontic bonding resin: 3~4 seconds
3. Veneer
* Tacking: 1~2 seconds
* Bonding: 4 seconds
It is recommended a timed curing test outside the mouth be performed. Using a 3mm
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 composite - it
should feel exactly the same if well cured.
Tips
Cooling - A simple cooling method is placing a suction tip or compressed air close to the
Light Head during or between uses. Do not overcure to avoid overheat. Another method is
Half Power Mode．
Half Power Mode - Press Unit Power Key during operation to switch to half power mode
(800mW/cm2) to minimize heat. Press Unit Power Key again to switch back to normal
power mode.
Connection - Ensure good mechanical and electrical contact at both junctions of Light Head
to Main Control and Battery Assembly to Main Control. Make sure there is no loose and
dirty connection. Clean contact as instructed below if needed.

5. Battery Maintenance
Battery Assembly uses a high capacity Lithium-Ion battery with built-in smart recharging electronics.
Keep light charged at all times when not in use by:
I: Drop and push the handpiece to the bottom of the Charge Stand.
II: Direct plug in the power jack from the Power Adapter to the receptor end of the handpiece.
III: Drop and push the handpiece into a Dental Unit Charge Holder (optional kit and accessory), which can
be mounted on a standard dental unit bar or cabinet bar (12) via its two bottom set screws. The Dental
Unit Charge Holder connects to Power Adapter through its outlet power jack 11a and extension cord
11b.
SMARTLIGHT INDICATOR is green while charging and turns off automatically when fully charged. The
battery capacity is indicated by the Battery Bar and displays three bars when fully charged. During
operation, the unit warns at low battery followed by automatic low power shutdown indicated with an
audible alarm as well as flashing backlight and battery bar.
To avoid battery power drain, shut down the unit power during storage or transport by pressing and
holding the Unit Power Key for 3 seconds until display is turned off indicated with a beep sound.
6. Safety Precautions
y Light must be used with barrier sleeves to avoid patient contact. Optional cap and shield are placed
outside the sleeve. Replace the barrier sleeve after each patient use. Handle and dispose of used
sleeves in accordance with accepted medical practice and applicable laws and regulations
y Do not touch and open any electronics parts and circuit boards. Warranty void if seal broken.
y Do not apply excessive force or use sharp objects on the keypads to avoid damage.
y Do not immerse handpiece in waters or solutions. Warranty void in case of liquid damage.
y The very high light intensity of FUSION results in a certain development of heat. Prolonged exposure of
the pulp and soft tissues may result in irreversible or reversible damage. This high-performance
polymerization light must only be used by specially trained dental personnel
- Do not place light directly on the same tooth segment for more than 10 seconds.
- Do not place light in direct contact with unprotected gingival, oral mucous membrane or skin.
Prevent heat accumulation with a rubber dam in place.
- Follow Cooling Tips to reduce contact heat.
- Adjust curing techniques in accordance with increase in curing energy: e.g., decrease curing time and
decrease power (Dual Power Switch).
y Do not look directly at light emitted from this curing unit. Do not use this device without suitable shield
or protective eyewear for the operator and assistant. Three levels of protective eye shields are offered by
DentLight: curing caps (partial eyeshield at the tip of the curing light), unit mount Eyeshield (mounts on
the chrome section in between the Light Head and Main Control), and eyeshield goggles.
y If time intervals between exposures are too short, LED tip may overheat and potentially cause soft tissue
injury. Do not continuously use the handpiece for over 2 minutes. It is recommended to wait for at least
30 seconds after continuous exposure of two minutes or when overheat alarm indicator has turned on
and using the Cooling Tips suggested.
y Charge batteries while not in use to extend the lifetime of the rechargeable battery.
- Do not short circuit battery.
- Do not store above 60°C (140°F).
- Dispose of unserviceable batteries and curing lights according to the national rules and regulations.
Batteries must not be incinerated.
- Replace the battery assembly after the lifetime of the battery usage by ordering replacement battery
assembly from the manufacturer.
7. Cleaning and Disinfecting
y Thoroughly wipe off handpiece and charge base with cleaning solution or soap and water. Do not
spray or soak. Disinfecting agents and water must not enter any openings on unit.
y Disinfect by thoroughly wiping down with a soft cloth or tissue damped with isopropyl alcohol.
y Clean curing lens and electrical metal contact using Q-tips slightly damped (do not soak) with isopropyl
alcohol.
y Always safeguard handpiece opening area, metal keypads, curing lens and LED tip against moisture as
this may cause electrical short-circuit, permanent optical damage or malfunction.

using a combination of 3mm, 9mm or 13 mm caps and Focus or
Expanded Beam Lens Module. The lens module can be switched
using the lens tool by aligning and locking the tool’s flat edge to
the flat edge of the lens mount and turning counter-clockwise
similar to unscrewing a nut. Clean thread following instruction in
7c. To replace the lens module, reverse the above step with a
replacement Lens Module. Example of obtaining different optical tips:
13mm tip: use Expanded Beam Lens Module (optional accessory) and snap on orange 13mm curing caps.
LED Light Head Options
Three optional light heads are offered.
Standard Light Head comes with the kit for LED light curing applications
with photoinitiators active to wavelengths from 420-490nm.
UV (Purple) Light Head option cures composite with photoinitiators
active to 385-425nm.
White Light Head option offers intra oral illumination and diagnostic tools for detecting dental caries and
diseases.
Dental Unit Charge Holder
This option provides the user a convenient mounting and charging option on a
standard dental unit or cabinet unit. See Section 5 for details.
