Lamp Life Timer
The lamp incorporates a passive mercury lamp life timer. This timer has an
unmarked scalar bar which indicates 0 to...

Conserving Lamp Life
As with all Xenon arc lamps, the Digital Projection lamp requires a very high strike
voltage (>30kV) to initiate the arc. This high voltage strike causes minute amounts
of material to be lost from the electrode tips. It has been identified that lamp with a
higher number of strikes can fail earlier.
To conserve lamp life, it is recommended that the user reduces the amount of strikes
as much as possible. For example, if the projector is not required for an hour during
a presentation it...

Stuck Lenses
Due to the introduction of physically larger lenses, over-tightening the lens, rotating
the lens too quickly in the lens mount or the presence of dirt in the threads of the
lens or mount may cause the lens to become stuck in the lens mount.
In order to prevent incidents of this nature, a fibre washer is now fitted to all new
lenses before shipping. Users with lenses shipped prior to the introduction of this
washer are advised to request them when placing their next order. Digital Projection...

Cleaning Optical Components
Airborne contaminants can deposit on exposed optical faces within the projector.
These deposits, by diffusing the light beams inside the projector, can adversely
affect light output and contrast ratio.
High levels of dust are created during construction or woodworking, both regular
activities during exhibition booth or set erection. Digital Projection recommends
that whenever possible, projectors mounted in the vicinity are turned off during
such activities.

2. For stubborn particles and/or grease based marks, wet the surface with an 
analytical grade isopropyl alcohol (IPA or propan-2-ol) and remove by gently 
drawing a lint free optical tissue across the surface - do not rub. It may be 
necessary to repeat the procedure until no smears or streaks are visible on the 
surface.
In some instances it may not be possible to gain access to draw a tissue across 
the surface and a rubbing action may have to be employed. In such cases try to 
keep a cushion of...
