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.

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 ZEISS Field
Service Engineer. Contact ZEISS Customer Service to arrange for a service call.
