OPERATION
Keep in mind that once the lamp power has reached its maximum of 700 watts (see "Constant
Power", above), this tracking is no longer possible. At this point, the lamp will gradually begin
to dim as usual, even though your original "Intensity" value will still appear in the menu. To
resume accurate tracking, reduce the intensity setting so that the resulting "Power" value is under
700 watts (VX-4c) and 1200W (VX-6c) - the lower the intensity, the longer it can be maintained.
Do not lower the "Intensity" so much that the corresponding "Power" value reaches its minimum
of 450 watts (VX-4c) and 800W (VX-6c) - the intensity setting will be inaccurate and cannot be
maintained.
NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily main-
tained as the lamp ages 2) Intensity can be set only if the lamp is in "Intensity" mode 3) Intensity
cannot exceed the output of Max Brightness mode.
XENON LAMP HISTORY - This read-only option lists the most
lamps most recently installed and recorded in the projector. Lamp
History automatically updates whenever you record a new lamp
serial number-the new lamp is added to the bottom of the list.
Use CHANGE LAMP to record theserial number for a newly installed lamp.
In the New Xenon Lamp S/N window, use the number text entry keys to record the new lamp seri-
al number, and press again to accept the change. See Using Slidebars and Other Controls if
you need help entering the number. Once entered, the new lamp serial number will be added to
the Xenon Lamp History menu and the Lamp Hours timer will reset to "0". Xenon Lamp Mode
and Lamp Limit remain as they were for the previous lamp, and can be changed at any time.
NOTE: Enter a serial number only if you have just installed a new lamp. This will help ensure
that lamp timer is not reset on an old lamp and that the number of hours logged on the lamp will
be accurate.
IMPORTANT
Always record the serial number of a NEW lamp.
