IMPORTANT SAFETY INSTRUCTIONS
When using your overhead projector, basic safety precautions should
always be followed, including the following:
1. Read and understand all instructions before using.
2. Close supervision is necessary when any projector is used by or
near children. Do not leave projector unattended while in use.
3. Care must be taken as burns can occur from touching hot parts.
4. Do not operate projector with a damaged cord or if the projector
has been dropped or damaged — until it has been examined by
a qualified serviceman.
3. Position the cord so that it will not be tripped over, be pulled or
contact hot surfaces.
6. If an extension cord is necessary, a cord with a current rating at
least equal to that of the projector should be used. Cords rated
for less amperage than the projector may overheat.
7. Always unplug projector from electrical outlet before cleaning
and servicing and when not in use. Never yank cord to pull
plug from outlet. Grasp plug and pull to disconnect.
8. Let projector cool completely before putting away.
9. To protect against the risk of electric shock, do not immerse this
projector in water or other liquids.
10. To avoid the risk of electric shock, do not disassemble this
projector, but take it to a qualified serviceman when some service
or repair work is required. Incorrect reassembly can cause electric
shock when the projector is used subsequently.
11. The use of accessory attachment not recommended by the
manufacturer may cause a risk of fire, electric shock or injury to
persons.
12. Connect this projector to a grounded outlet.
13. Disconnect this unit from its source of supply before replacing
the projection lamp.
Additional lamp safeguards: never handle lamps with bare fingers;
periodically inspect lamps, when they’re turned off, for signs of
blistering or blackening; insure proper action of the cooling system;
turn off the projector immediately if the image becomes abnormally
dim; never operate a projector with the lamp housing open; and make
sure that the lamp itself is properly seated.

Professional Overhead Projectors
The Models 663, 4003, 4300 and 5500 feature a special optical design
which combines a standard three-element (13") projection lens with a
movable fourth element that converts to a wide angle (11”) lens.
This design allows you to maintain image size for both transparency
and the smaller LCD panel aperture size. Other features include a
lamp changing mechanism and spare lamp indicator that will light
up to remind you to replace the primary lamp.

5 - OPERATION
Place the projector on a stable surface that is desk or table height.
Make sure that the side vent is not blocked. Plug the power cord
into a standard 120V AC outlet. Push the power button in to turn the
projector on. Place a transparency on the stage. If the fourth element
lens is in place, an enlarged view of the transparency will be pro¬
jected. For a standard size view of the image, carefully pull the
fourth element lens towards the projector’s mast and away from the
lens head (see Fig. 1). Adjust the focus by turning the focusing
knob. You may alternate between the wide angle and standard lens
by moving the fourth element lens towards or away from the lens
head (you may need to adjust the distance of the projector from the
screen).
The Model 640/653A/663 and 4000/4003/4300/3300 lamp changing
device allows you to quickly replace a failed lamp. Simply slide the
lamp changing lever towards the side labeled “SPARE 2.” The spare
lamp indicator will light up to remind you to replace the primary lamp
