Stimulus Projection Lamp
This lamp is responsible for projecting the standard light stimulus. W
ith the aid of color filters, it is
also used to create red and blue stimuli for color testing. If needed, you may order a new lamp by
calling the Carl Zeiss Meditec Parts Department and asking for PN 2660021106082 (Projection
Lamp).
1Turn off the HFA II-
i
and lower the table. To remove the top access panel, rotate it
counterclockwise until you align the lamp symbol on th
e cover with the raised dot that is molded
into the top of the case. Standing in front of the bowl opening, you will find that the projection
lamp is located inside the open case top, at the 12 o’clock position. Allow the lamp to cool
completely (approximately five minutes) before handling it. Do NOT touch the two disk-shaped
filters.
2Remove the connector cable by pulling its connector straight upward. Then use a screwdriver
to loosen the screw.
