In addition, the LED’s next to the built-in keypad will flash “LP” when lamp time
has expired. The lamp should be replaced.
The “Lamp Limit” setting should not exceed the warrantied lamp lifetime, as an old
lamp becomes increasingly fragile and more prone to sudden failure.

The read-only
Status
menu lists a variety of details about the standard and optional
components currently detected in the projector. Refer to the
Status
menu for versions
of hardware and software installed, the type (size) of lamp defined in projector
memory, and hours logged in total and for a specific period (such as a rental period),
and for your projector model name and serial number. In addition, the
Status
menu
identifies the current channel, its location, its frequencies and other details.

When an installation requires multiple projectors, you can use the RS232 serial ports
to daisy-chain the units together and control the group with a single keypad or a
computer/controller connected to the first projector. In such a network, you can
choose to broadcast commands to the entire group, or use the
Proj
key as desired to
limit responses to an individual projector.
Alternatively, you may want to add projectors to a hub on an Ethernet network. See
2.6, Connecting Multiple Projectors
for full routing details.
NOTE:
Refer back to
3.7, Adjusting System Parameters and Advanced Controls
for
complete information about communicating with multiple projectors.
In a multiple-projector wall, you will likely want to precisely match color and intensity
from image-to-image so that the full wall is as uniform as possible. This matching is
typically done in conjunction with brightness uniformity and edge blending.
Preliminary Calibration
As a final part of the manufacturing process, all primary colors in the projector are
precisely set to pre-established values to ensure that overall color performance is
optimized and is as accurate as possible (refer back to Figure 3.23). Upon installation
at a site, however, lighting and other environmental factors may slightly change how
these colors appear on your screen. While the change is negligible in most cases, you
may prefer to recover the originally intended color performance before trying to
match colors from several projectors. Or you may be renting a projector in which the
colors were corrected for use at its previous site, but are not ideal for yours.
The recommended first step in achieving such consistency is to use a color meter to
measure the native primary colors—red, green, blue, and white—as they appear at
the screen and record these as
Color Primary Settings
in the
Service
menu (password-
protected) for each projector. On the basis of these new values, which are stored in
memory, each projector will then automatically calculate any necessary corrections to
reproduce the original factory colors under the current environmental conditions.
This essentially calibrates a projector to its surroundings, compensating for factors
such as screen type; lamp and/or ambient lighting that can alter the final color
characteristics on-screen, and will improve color accuracy and consistency in a group
of projectors. It ensures a good starting point for further customizing and matching;
however, is not critical for all installations.
