The “Safeguards” statement reproduced below is in accordance
with Underwriters Laboratories “Standard for Safety, UL 122,
Photographic Equipment.”
IMPORTANT SAFEGUARDS©
When using your photographic equipment, basic safety precautions
should always be followed, including the following:
1. Read and understand all instructions.
2. Close supervision is necessary when any appliance is used by
or near children. Do not leave appliance unattended while in
use.
3. Care must be taken as burns can occur from touching hot parts.
4. Do not operate appliance with a damaged cord or if the appli-
ance has been dropped or damaged—until it has been exam-
ined by a qualified serviceman.
5. Do not let cord hang over edge of table or counter or touch hot
surfaces.
6. If an extension cord is necessary, a cord with a suitable current
rating should be used. Cords rated for less amperage than the
appliance may overheat. Care should be taken to arrange the
cord so that it will not be tripped over or pulled.
7. Always unplug appliance from electrical outlet when not in use.
Never yank cord to pull plug from outlet. Grasp plug and pull to
disconnect.
8. Let appliance cool completely before putting away. Loop cord
loosely around appliance when storing.
9. To protect against electrical shock hazards, do not immerse this
appliance in water or other liquids.
10. To avoid electric shock hazard, do not disassemble this appli-
ance, but take it to a qualified serviceman when some service or
repair work is required. Incorrect reassembly can cause electric
shock hazard when the appliance is used subsequently.

ASSEMBLY INSTRUCTIONS (FIG. 1)
OPERATING INSTRUCTIONS
The G-200 overhead projector comes packaged in two
basic assemblies–the projection light box and the post -
head assembly. Instructions for assembly are as follows:
1. Remove 2 screws (A) from post.
2. Insert post into square hole in projector lid. Align
holes in post with holes on the side of the projector
lid.
3. Insert 2 screws (A) and tighten.
The G-200 overhead projector is now ready for
operation.
1. Set the projector, with the switch facing the screen,
on a projection table. Make sure the projector is
placed at a projection distance consistent with the
size of the screen, as indicated in the projection table
on page 2.
2. Connect the power cord to a suitable grounded
electrical outlet (refer to nameplate for electrical re-
quirements.)
3. Turn on the switch.
4. Place projection copy on projection stage.
5. Raise or lower image on screen by tilting top portion
of projection head. (Do not touch lens elements.)
1
6. Focus image on screen by turning the focusing knob,
which raises or lowers the projection head.
7. To turn off the projector, simply push the switch
down.
8. The G-200 is supplied with a safety thermal switch to
prevent fresnel or light box overheating. In the event
of motor malfunction or tampering, the G-200 lamp
will shut off automatically due to temperature rise.
(UL listed system.)

LAMP REPLACEMENT
CAUTION: LAMP CAN BE EXTREMELY HOT!
1. Allow the overhead projector to run for four or five
minutes after the lamp burns out. The fan should cool
the burned out lamp and prevent injury when you at-
tempt to replace the lamp.
2. Turn off the projector and disconnect the power cord
from the electrical outlet. Although the G-200 is
equipped with a safety interlock switch that cuts off
current when the projection stage is lifted, it is con-
sidered an additional safety precaution to disconnect
the power cord.
3. Remove the cover lock screw on the side of the unit
and lift up the cover to expose the inside of the pro-
jector. The bracket located near the cooling fan will
hold the lid open (A) (see Fig.2).
4. Hold bulb by the ceramic base and pull it out of the
socket (see Fig. 2).
5. To install a new lamp, hold lamp by the ceramic base
and insert the two pins on the lamp into the matching
holes in the socket.
NOTE: Make sure the lamp is pushed into the socket
completely, otherwise the filament of the lamp will not
be properly located.
6. Close the projector lid, see Fig. 3.
1. Lift up slightly on lid.
2. Pull up on bracket.
3. Lower lid.
NOTE: Replace lamp with type EYB 360 watt 82 volt bulb
only.
CLEANING AND MAINTENANCE
The G-200 overhead projector needs minimal mainte-
nance to keep it operating in peak condition. It is only
necessary to keep the optical elements clean and to re-
place lamps when necessary. Remove dust from optical
elements with a soft, lint-free cloth.
If the elements are very soiled, carefully remove them
and clean with lens tissue or a soft, water-dampened,
lint-free cloth. Dry thoroughly with a lint-free cloth.
Remove dust from the reflector every time the lamp is
changed.
