SHOWMATION AUTOMATION
ELECTRICAL INTERFERENCE WARNING
This device utilizes sophisticated computerized micro-controller devices and
other parts which may be susceptible to externally produced electro-magnetic
interference (EMI).This type of interference may be found in and around
projector lamphouses which are not very clean electrically and magnetically. It
is imperative to make certain that all sources of EMI are properly suppressed if
this device is to perform to its full potential. By far, the worst offender is the
Xenon lamp ignitor, and many lamphouses, especially older ones, have
extremely electrically dirty ignitors. Please see the diagram below for suggested
ways to clean up the lamphouse. Having an EMI suppressed system is your
responsibility, and SMART assumes no responsibility for failures due to
excessive interference.

Keep all capacitor leads as
short as possible with the
most direct connection to
chassis ground, 2 to 3 inches
at most. Long leads will
degrade suppression. Mount
all capacitors as close as
possible to where leads exit
lamphouse.
