loosening the 3 Phillips screws on the cover.
Gently pull out the lamp assembly.
If changing the lamp, remove the old lamp from the socket. Insert the lamp to the socket.
Do not install a lamp with a higher wattage! A lamp like this generates temperatures the device is not designed
for.

lampholder system.

and "Down" buttons in one time and then confirming with the Enter-button.

4.2 Lamp adjustment
The fixture lampholder is aligned at the factory. Due to differences
between lamps, fine adjustment may improve light performance.
Strike the lamp and focus the light on a flat surface (wall).
Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws „A, B, C”.Turn one screw at a time to drag
the hot-spot, diagonally across the projected image. If you cannot
detect a hot -spot, adjust the lamp until the light is even.
To reduce a hot-spot, pull the lamp in by turning all three screws
„A, B, C” clockwise 1/4-turn at a time until the light is evenly
distributed.
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.
„Push” the lamp out by turning the screws „A, B, C”
counterclockwise 1/4-turn at a time the light is bright and evenly
distributed.
