Remove the old expended lamp assembly. Insert the replacement lamp into the housing. Note
the notch in the base of the lamp housing lines up with the pin to the right of the assembly. Do
NOT touch the glass part of the lamp with your fingers, as this will shorten the life expectancy of
the lamp. If your finger touches the glass portion of the lamp, wipe the lamp clean with a soft
cloth.

Slide plate back into position, tighten screw and replace connector cable.

To replace the top access panel, insert the panel into the opening. As you do so, align the lamp
image on the lid with the raised dot on the underlying case. Rotate the panel clockwise until the
lamp symbol aligns with the open-circle symbol.
Background Illumination Lamps
The lamps responsible for illuminating the bowl surface are a fluorescent type (not incandescent)
and have a long life expectancy. If you get a bowl illumination error, darken the room and restart
the instrument to see if this corrects the problem. If the bowl illumination error continues, do NOT
attempt to replace the lamp. These highly specialized lamps are to be replaced only by a Carl Zeiss
Meditec Field Service Engineer. Contact Carl Zeiss Meditec Customer Service to arrange for a service
call.
