By default, the filter is set to None. To change this, edit your surgeon preferences file (see page 3-9 ).

Lamp Life Cycle
As the lamp ages, its operating voltage will naturally increase. In some cases it may increase beyond an
acceptable level before the normal number of operating hours have elapsed. In this case the
Stellaris® PC
Vision Enhancement System will prevent further use of the lamp to avoid the possibility of lamp rupture.
If the lamp takes longer than usual to strike, or fails to strike, this indicates the lamp is nearing the end of its life
and a warning message may appear on the screen.
Each lamp has a maximum number of hours of life, and the system will provide a warning when that limit is
near, and again once the limit has been reached. Once the limit has been reached, the lamp will remain on for
the current surgery but once turned off will not turn on again and must be replaced.
The amount of lamp life remaining for each lamp is displayed in the
Illumination More Screen
. The display
represents the remaining hours of lamp life. The Green area represents the amount of hours of life remaining
prior to the user notification, the Yellow area represents the point that the user notification has been given,
meaning that the lamp has a specific number of hours (15) until the indicated light bulb must be replaced.
Lamp Life
Xenon—400 hours, notification is at 15 remaining hours of lamp life
Xenon-Mercury—500 hours, notification is at 15 remaining hours of lamp life
Lamp Replacement Procedure
WARNING: Always turn off the power supply before attempting to replace the lamps to avoid danger of
