/$03= Do not operate the Xenon lamp for more than 1000 hours; risk of the lamp
shattering increases as a result of changes in the quartz glass. Also, operation
beyond 1000 hours significantly reduces brightness output.

The arc lamp operates at a very high temperature and
pressure. Failure to allow the lamp to sufficiently cool prior
to handling could result in an explosion causing personal
injury and/or property damage. After turning the projector off
it is important that you wait at least five minutes before
unplugging it. This provides enough time for the internal lamp cooling fans to
cool the lamp and to automatically shut off. Cool completely before handling.

),/7(5= Replace the side filters every 1000 hours or sooner. If these filters are
not replaced, air flow may become restricted and cause the projector to overheat.
See

procedure.

Do not allow anything to rest on the power cord. Locate the projector where the
cord cannot be abused by persons walking on it or objects rolling over it.
Operate the projector at the specified voltage. Do not overload power outlets and
extension cords as this can result in fire or shock hazards.
The projector is equipped with a three wire plug having a third (grounding) pin.
This is a safety feature. If you are unable to insert the plug into the outlet,
contact an electrician to have the outlet replaced. Do not defeat the safety
purpose of the grounding-type plug.
Before unplugging the power cord, make sure the internal
lamp cooling fans have shut off. The fans automatically shut
off when the projector has adequately cooled down. /DPS#DQG#)LOWHU#

Slots and openings in the projector provide ventilation. To ensure reliable
operation of the projector and to prevent overheating, these openings must never
be blocked or covered. The projector should never be placed near or over a
radiator or heat register. The projector should not be placed in an enclosure
unless proper ventilation is provided.
Do not push objects of any kind into the projector through the ventilation
openings. They may touch dangerous voltages or short-out components resulting
in a fire or shock hazard. Do not spill liquids of any kind into the projector.
Should an accidental spill occur, immediately unplug the projector and have it
serviced by a qualified service technician.
If any of the following conditions exist, unplug the projector from the power
outlet and refer service to qualified service personnel.
· The power cord has been damaged.
· The internal cooling fans do not come on when the projector is first turned on.
· Liquid has been spilled into the projector.
· The projector has been exposed to excessive moisture.
· The projector does not operate normally.
· The projector has been dropped or the case has been damaged.
· Projector performance has deteriorated.
Do not attempt to service the projector yourself. All servicing must be performed
by a qualified Electrohome service technician. If replacement parts are required,
it is important that only Electrohome-approved parts are used. Other parts may
result in fire, electric shock or risk of personal injury.
Clean the projector when required. Before cleaning, always unplug the projector
from the power outlet.
To avoid the risk of scratching the lens, only clean the lens if absolutely
required. A small amount of dust on the lens will have very little effect on
picture quality. If the lens must be cleaned, use a DRY soft cotton cloth. Clean
gently in a circular motion.
It is important to never touch the sapphire (glass) surface of the lamp, as the oil
imprint will seriously degrade lamp performance. The wire mesh protector
should prevent this. However, should you accidentally touch the surface of the
lamp, clean carefully with a lint-free cloth moistened with isopropyl alcohol.
Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do
not use liquid or aerosol cleaners.
The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably
alkaline). To install new batteries, open the battery compartment at the back side
of the keypad by pulling on the raised portion of the cover as shown (Figure 4.1) 6HUYLFLQJ

Remove the old batteries and properly discard. Place the new batteries in the
compartment, orienting the positive/negative of each battery according to the
labels in the compartment. When batteries are in place, replace the cover by
inserting its bottom edge first and snapping the top into place. Do not force.

For this procedure you will need a VistaGRAPHX 10K Lamp Assembly and Filter
Replacement Kit manufactured by Electrohome Ltd.
The high brightness of Vista
GRAPHX 10K is provided by a 1.8 kilowatt Xenon
lamp permanently mounted inside a rugged metal housing. When the bulb
approaches 1000 hours of usage the entire lamp assembly needs to be replaced.
+RZ#2OG#LV#WKH#/DPS
To determine how many hours the lamp has been used, press 
0HQX and go to the
Status menu. Lamp Hours indicates the total number of hours the lamp has been
used so far — do not confuse this with the adjacent Lamp Counter, which
indicates only the number of hours logged during the current rental period.
NOTE: As the lamp nears 1000 hours of use, a lamp timer message can appear
on screen to warn that the lamp is in need of replacement. To make sure that this
warning appears, enter a checkmark in the 
Lamp Timer Message checkbox on
the 
Preferences menu.

Place the old lamp assembly in the new lamp box 
and send it to your nearest
Electrohome service depot for re-lamping (see back cover of this manual).
Make sure the lamp is packed properly and label the carton “freight collect” for
free shipping.
NOTE: Your voluntary participation in this relamping program is
strongly encouraged, and helps ensure that Electrohome can
continue to offer economical replacement lamps having the same
warranty as new. Once you have returned a used lamp, you are
entitled to the purchase of an economical “re-lamped” lamp module.

With the lamp lens facing the projector, align the lamp assembly with the lamp
compartment — handles are on the top and bottom. Carefully slide the assembly
into the projector (Figure 4-6). When it feels as though it is in place, push very
firmly once more to ensure that the unit is properly seated as far back as
possible.
