Bulb Replacement

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 place-
ment or missing a heat filter could lead to tissue
burn. Send curing light to an authorized service cen-
ter.
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 inte-
gral 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. 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 part number 78-8045-4571-9 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.

Light Guide Replacement:

guide could still be very hot.
1. Hold the handpiece by placing one hand firmly around the nose cone area.
2. Grasp the light guide firmly with the other hand.
3. Pull light guide straight out of nose cone receptacle.
4. Push replacement light guide firmly into nose cone receptacle.
