[Important 1] Operating the Lamp Continuously
If using the projector continuously for a long period, use of the menu (OSD) is recom-
mended in order to properly cycle the lamps as described below.
To use the projector continuously in the dual lamp mode
Allow 2 hours per day of non usage time per lamp. Do this for both lamps at the same
time or for “Lamp 1” and “Lamp 2” at separate 2 hour intervals.
To use the projector continuously in single lamp mode
Use the two lamps (Lamp 1 and Lamp 2) alternately in a cycle of 24 hours or less.
Allow 2 hours or longer per day of no-use time for each lamp.
Contact your dealer for more details.
Note:
If using the menu, select "Off" for "Lamp Interval" from the on-screen menu
(see page
82 ).
