Bulb Replacement

CAUTION

To avoid risk of burn, make sure the cooling fan has completed the cooling cycle and has stopped rotating. Turn off the main switch. Disconnect the power cord from the wall outlet.

Do not attempt to replace any filters. Improper placement or missing a heat filter could lead to tissue burn. Send curing light to an authorized service center.

1.Remove the nose cone by placing the thumb on a textured snap-in tab located between two slits and the forefinger on the other textured snap-in tab located between two slits.

Gently squeeze the tabs while pulling downward at an angle to separate the nose cone from the handpiece.

2.Grasp the outside rim of the reflector and pull it forward, separating the bulb pins from the socket. The bulb and integral reflector are changed as a unit.

Note: Inspect the optical filter in the nose cone. Remove dust or other contaminants with a soft cotton swab. A chipped or cracked filter should be replaced immediately by an authorized service center.

3.3. Hold the new bulb/reflector unit by the reflector rim. Align the bulb pins and push the unit securely into the socket. To ensure expected performance and safety, replace bulb with 3M ESPE part number 78-8131-1662-7 only.

Note: Fingerprints on the inside of the reflector or the bulb can adversely affect performance. Remove fingerprints with a cotton swab moistened slightly with alcohol.

4.Replace the nose cone by holding it at a slight angle

to the handpiece. Insert the side opposite the snap-in tabs into the groove of the handpiece. While gently squeezing the tabs, rotate the nose cone to align it into the handpiece until it is fully seated and snaps into position.

5.Release the snap-in tabs and rotate the nose cone on the handpiece to assure it is correctly positioned and rotates freely.
