5 Holding the new lamp by its ceramic base (do not touch the glass), align the
small pin with the small hole and insert the lamp squarely into the socket. Make
sure that the 4 small projections on the base contact the socket.
6 If your fingers touched the glass bulb, clean it with a clean, lint-free cloth
wetted with alcohol.
7 Insert the lamp assembly and replace the screws (A).
8 Reset the lamp hour and lamp strike counters as described on page 16.
To al ign the lamp
The lamp is pre-aligned at the factory. Realignment when changing the lamp may
improve performance.
1 Strike the lamp and shine the light on a flat surface.
2 Center the hot-spot (the brightest part of the beam) with small turns of the
adjustment screws (B) using a Pozidriv #2 screwdriver. If there is no hot-spot,
adjust the reflector until the light is even.
3 To reduce a hot-spot, turn all 3 screws clockwise (B) 1/4-turn at a time until the
light is evenly distributed.
4 If the light is brighter around the edge than it is in the center, or if light output is
low, the lamp is too far back in the reflector. Turn the adjustment screws (B)
counterclockwise 1/4-turn at a time until the light is bright and evenly
distributed.
5 If you have trouble aligning the lamp, remove the lamp and check that it is
seated squarely in the socket.
