Relays
To prevent a contact fault, etc., relays must be changed according to the number of accumulative switching
times (switching life is approximately 30,000 rides).
6-3 Projector Bulb
To prevent an excessive down time, due to the projector bulb burning out, obtain a spare bulb whenever the
INFOCUS run time states over 750 hours. We do not know at this time how long this bulb lasts. This is
only a suggestion for having on hand this spare part, not a requirement.
Note: Projector bulbs can be obtained from Infocus direct by ordering from a local distributor or going on
the internet to (
WWW.INFOCUS.COM ). Also the projector is warranted by Infocus direct by a pass
through warranty. Any maintenance done to the projector will void the warranty. Should you require a
loaner, Infocus will overnight delivery you a loaner for a fee if given a major credit card.
