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 18.
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.
