The wires of the mains lead are colored in accor-
dance with the following code.
Green and yellow: earth (safety earth)
Blue: neutral
Brown: line (live)
B. Power cord with ANSI 73.11 plug:

3. Do not allow anything to rest on the power
cord. Do not locate this product where persons
will walk on the cord.
To disconnect the cord, pull it out by the plug.
Never pull the cord itself.
4. If an extension cord is used with this product, make sure that the total
of the ampere ratings on the products plugged into the extension cord
does not exceed the extension cord ampere rating. Also make sure that the
total of all products plugged into the wall outlet does not exceed 15
amperes.
5. Never push objects of any kind into this product through cabinet slots
as they may touch dangerous voltage points or short out parts that could
result in a risk of fire or electrical shock.
Never spill liquid of any kind on the product. Should any liquid or solid
object fall into the cabinet, unplug the set and have it checked by quali-
fied service personnel before resuming operations.
6. Lightning - For added protection for this video product during a light-
ning storm, or when it is left unattended and unused for long periods of
time, unplug it from the wall outlet. This will prevent damage to the pro-
jector due to lightning and AC power-line surges.
On installation
1. Do not place this equipment on an unstable cart, stand, or table. The
product may fall, causing serious damage to it.
2. Do use this equipment near water.
3. Slots and openings in the cabinet and the back or bottom are provided
for ventilation; to ensure reliable operation of the product and to protect
it from overheating, these openings must not be blocked or covered. The
openings should never be blocked by placing the product on a bed, sofa,
rug, or other similar surface. This product should never be placed near or
over a radiator or heat register.
The projector should not be placed in a built-in installation or enclosure
unless proper ventilation is provided.
4. Do not block the projector cooling fans or free air movement under and
around the projector. Loose papers or other objects may not be nearer to
the projector than 4” on any side.
On servicing
Do not attempt to service this product yourself, as opening or removing
covers may expose you to dangerous voltage potentials and risk of elec-
tric shock!
Refer all servicing to qualified service personnel.
Unplug this product from the wall outlet and refer servicing to qual-
ified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the equipment.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally when the operating instruc-
tions are followed.
Note: Adjust only those controls that are covered by the operating instruc-
tions since improper adjustment of the other controls may result in dam-
age and will often require extensive work by a qualified technician to
restore the product to normal operation.
e. If the product has been dropped or the cabinet has been damaged.
f. If the product exhibits a distinct change in performance, indicating a
need for service.
Replacement parts - When replacement parts are required, be sure the
service technician has used original RUNCO replacement parts or autho-
rized replacement parts which have the same characteristics as the
RUNCO original part. Unauthorized substitutions may result in degraded
performance and reliability, fire, electric shock or other hazards. Unau-
thorized substitutions may void warranty.
Safety check - Upon completion of any service or repairs to this projec-
tor, ask the service technician to perform safety checks to determine that
the product is in proper operating condition.
On Cleaning
Unplug this product from the wall outlet before cleaning. Do not use
liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
- To keep the cabinet looking brand-new, periodically clean it with a soft
cloth. Stubborn stains may be removed with a cloth lightly dampened
with mild detergent solution. Never use strong solvents, such as thinner
or benzine, or abrasive cleaners, since these will damage the cabinet.
- To ensure the highest optical performance and resolution, the projection
lenses are specially treated with an anti-reflective coating, therefore,
avoid touching the lens. To remove dust on the lens, use a soft dry cloth.
Do not use a damp cloth, detergent solution, or thinner.
On repacking
Save the original shipping carton and packing material; they will come in
handy if you ever have to ship your equipment. For maximum protection,
repack your set as it was originally packed at the factory.
On illumination
In order to obtain the best quality for the projected image, it is essential
that the ambient light which is allowed to fall on the screen be kept to an
absolute minimum.
When installing the projector and screen, care must be taken to avoid
exposure to ambient light directly on the screen. Avoid adverse illumina-
tion on the screen from direct sunlight or fluorescent lighting fixtures.
The use of controlled ambient lighting, such as incandescent spotlight or
a dimmer, is recommended for proper room illumination. Where possible,
care should also be taken to ensure that the floors and walls of the room
in which the projector is to be installed are non-reflecting, dark surfaces.
Brighter surfaces will tend to reflect and diffuse the ambient light and
hence reduce the contrast of the projected image on the screen.
