coded warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message always remain set to

cancel the message. The message will continued to appear upon power-up until
you install a new lamp.
Set
to the number of hours you expect to log on the current lamp
before replacing it. The recommended value you set here depends on the lamp
mode you have selected. Consider the following as a general guide:

NOTE: 1) If you change modes over the life of a lamp the original lamp limit
setting will no longer be valid. 2) Turning the lamp on and off reduces lamp life
significantly, as do other factors. Consider Table 3-1 as a rough guide only.
Set which
life span of the lamp. The higher the light output or power setting, the shorter the
life span of the lamp.
Figure 3-19. Choosing a Lamp Mode
Lamp modes are described below:
•
The lamp will burn as brightly as possible for its lifetime. Keep
in mind that the lamp's "maximum brightness" gradually diminishes with
age—your image will become dimmer over time, shown in "Intensity".
•
The lamp will last as long as possible. Unlike "Max Brt", a
reduced power level is applied to the lamp, so image brightness is
likewise reduced and lamp life extended.
•
Brightness will remain at a specified level for as long as
possible. Once you select this option, enter a number representing the
intensity level (brightness) you wish to maintain. See "

Use the lamp mode that best suits your
needs. For example, in a tiled
application you may want to precisely
match brightness levels between
adjacent DLV 1280 images—choose
each individual intensity setting as
necessary (see "Intensity", below). Or
you may not need full light intensity
and prefer to extend lamp life as long
as possible—choose
