instructions on installing a new lamp assembly.
WARNING
If you enter a serial number and select the "Accept"
button WITHOUT having installed a new lamp, the
timer will incorrectly return to "0" and will therefore
no longer be accurate. The old lamp may expire
without warning.
NOTE: Once entered, the new lamp serial number is also automatically added to
the "Lamp History" list of lamp serial numbers in the Service menu (password-
protected).
The Service menu is password-protected and can be used by qualified service
personnel only. However, test patterns from the Service menu can be accessed

When working with multiple projectors, you may want to use the RS-232 ports
to chain the projectors together in a network that you control from either a
keypad or a computer/controller (see 2.9, Serial Port Connections). Or you may
prefer that each projector stands alone, in which case you will probably use a
single IR remote keypad. In either case, you can switch back and forth between
broadcasting to all projectors or controlling each projector individually.
Make sure you have assigned a unique projector number to each projector
present — this number will be required in order get the exclusive attention of an
individual projector. To assign a projector number:
Press and select the Preferences icon. In the Preferences menu, scroll
down to "Projector#" and enter a three-digit number (000 to 999) to identify the
current projector. Press
to accept the entry and return to the main menu.
