Charge BATTERY ASSEMBLY: 2. Assemble handpiece: Before use, charge Battery Assembly overnight by either direct plugging the Power Adapter or through the Charge Stand. Push down LED Light Head and quick connect with Main Control Unit. Turn Battery Assembly clockwise and screw-on connect with Main Control Unit. 3. Power on handpiece and Select Mode PRESS AND HOLD the Unit Power Key for 5 seconds until LCD display turns on. Press Menu Key to select operation mode . Use smooth side of thumb and apply normal force (a) (b). Do not point finger nail or use sharp object forcing the keypads (c) (d). Digital LCD displays operation mode (1, 2, 3, 4, 5, 10 and 20) when pressing Menu Key successively. Seven modes are grouped in Sequential and Constant Power modes. Constant power mode is recommended for sealants and composite curing. Sequential mode is recommended for full arch veneer tacking (1 or 2 sec per tooth) and bonding (3 or 4 sec. per tooth), and full arch bracket bonding (3 or 4 sec. per bracket).

DIGITAL TIMER counts down in seconds. Press On/Off Key any time to stop. BACKLIGHT 5: Cure Times Average curing time of shade A2 (2mm thick) composites is 3 seconds. Darker shades or thicker composite may require additional times. 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. 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 the 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 in the battery bar on the LCD display and displays full bars when fully charged. During operation, unit warns at low battery and turns off with audible alarm, flashing backlight and battery bar. To avoid battery power drain, shut down the unit power during storage or transport by pressing while holding on the Unit Power Key for 3 seconds until display is turned off indicated with a beep sound. 6. Tips Cooling - Handpiece shuts down for 15 seconds when overheated accompanied by LCD flashing THERMAL STATE symbol and keypad backlight together with audible alarm. A simple cooling method is placing a suction tip or compressed air close to the Light Head during or between use or when it just shuts down. 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) in procedures for preparation of liners and bases or to reduce shrinkage. Press Unit Power Key again to switch back to normal power mode. Handpiece works longer time in Half Power mode generating minimum heat. 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. 7. Safety Precautions 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 Do not touch and open any electronics parts and circuit boards. Warranty void if seal broken. Do not apply excessive force or with sharp object to the keypads to avoid damage. Do not immerse handpiece in waters or solutions. Warranty void in case of liquid damage. 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). 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. 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 (section 6) suggested. 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. 8. Cleaning and Disinfecting a) Thoroughly wipe off handpiece and charge base with cleaning solution or soap and water. Do not spray. Disinfecting agents must not enter openings on unit. b) Disinfect by thoroughly wiping down with a soft cloth or tissue damped with isopropyl alcohol. c) Clean curing lens and electrical metal contact using Q-tips slightly damped (do not soak) with isopropyl alcohol. d) Always safeguard handpiece opening area, metal keypads and LED tip against moisture as this may cause electrical short-circuit or dangerous malfunction. 9.
