SAFETY SUMMARY

Please read these instructions carefully before using your projec­tor. Failure to comply with them could result in fire, electrical
shock, personal injury or damage to equipment.

These graphics are used throughout this manual to draw your
attention to important information about the projectors.

NOTE: Additional useful details or tips.

CAUTION: Steps to take to avoid damage to your equipment.

WARNING: Steps to take to avoid personal injury.

These graphics are used on the projector ’s labels.

Attention - Refer to this User’s Guide for important

safety information.

CAUTION- Hot Surfaces - Avoid touching hot surfaces.

Do not touch until the projector has cooled.

Do Not Look Into The Lens!

Be extremely careful not to lo ok into the pr o jection len s when th e
projector is turned on. The bright light may harm your eyes. Be
especially careful to keep children from looking into the lens.

Power Source

Use only a three-wire grounding type power source. The power
source should not exceed 250 volts rms between the supply con­ductors or between either conductor and the ground.

Power Cord

Use only the power cord that was shipped with the projector.
Although other power cords might be similar in appearance, they
have not been safety-tested with the projector. Do not use a
power cord if it has become damaged or frayed. Contact Boxlight
at 1-800-762-5757 if you need to replace your power cord.

iii

Safety Summary

Grounding

The projector is grounded through the grounding conductor on
the power cord. To avoid electric shock, plug the power cord into
a properly wired receptacle. Do not defeat the purpose of the
grounding-type plug.

Lamp

T o avoid over heating and unacceptable image quality, replace the
projection lamp with a lamp of the specified type. Refer to
page 49 for lamp specifications and to page 41 for instructions on
replacing the lamp.

Lamp Compartment

To avoid burns, do not open the lamp module door until the pro­jector is turned off and the lamp has cooled for at least 30 min­utes. Follow the instructions in this manual for lamp replacement
carefully.

Hot Surfaces

Allow the projector to cool at least 30 minutes before replacing a
lamp. When you open the lamp housing, be very careful not to
touch the hot surfaces inside.

NOTE: If you open the projector

case, you will void the warranty.

iv

Ventilation and Overheating

Openings in the projector case provide ventilation to protect it
from overheating. Keep loose papers and other objects well away
from the grills. Do not place the projector on top of or close to a
computer or other heat-producing equipment.

Liquid Spills

Do not set drinks on top of the projector. Spilled liquids can flow
inside and cause damage.

Do Not Disassemble

All projector service must be performed by Boxlight. The only
user-serviceable part in the projector is the projection lamp,
which you can replace by opening the lamp cover on the bottom
of the projector (see page 41). Do not open any other part of the
projector.

INTRODUCTION

The Boxlight 3750 and 6750 lightweight multimedia projectors
combine powerful and sophisticated features with easy-to-use,
intuitive controls. Built-in multimedia features include audio, a
palette of 16.7 million colors and active matrix liquid crystal dis­play (LCD) technology. The projectors are ideal for high-perfor­mance business, training and imaging applications that demand
exceptional color quality. The 3750 has SVGA 800x600 graphics,
the 6750 has XGA 1024x768 graphics. The user interfaces of the
two products are identical; information in this User’s Guide
applies to both products.

NOTE: For models 3750-INT or
6750-INT: To use video input, an
optional video board must be
installed in the projector. Contact
Boxlight for more information.

Usage Guidelines

•

Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.

•

Do not block the grills on the projector. Restricting the air flow
can cause it to overheat and turn off.

•

Handle the projector as you would any product with glass
components. Be especially careful not to drop it.

•

Avoid leaving the projector in direct sunlight or extreme cold
for extended periods of time. If this happens, allow it to reach
room temperature before use.

•

This projector is not intended for use in a mainf ram e computer
room as defined in the Stand ar d for th e Pr otection of E lectr onic
Computer/Data Processing Equipment, ANSI/NFPA 75.

•

Transport the projector in a vendor-approved hard or soft case.
These cases are listed on page 52. Call Boxlight to order.

If You Need Assistance

The first place to look for help is in this manual. Be sure to check
the guidelines in “Troubleshooting” on page 44.

If this manual doesn’t answer your question, call Boxlight at

1-800-762-5757

.

NOTE: If the projector overheats
and turns off, you must wait about
30 seconds before you attempt to
turn it back on.

Warranty

This product is backed by a limited one-year warranty. The
details of the warranty are printed at the back of this manual.

SETTING UP THE PROJECTOR

1 Place the projector on a flat surface.

•

The projector must be within 10 feet (3 m) of your power
source and within 10 feet of your computer.

•

If you want to project from behind a translucent screen, set
up the projector behind your screen. See “Rear Projection”
on page 38 to reverse the image.

•

If you are installing the projector on the ceiling, refer to the
Ceiling Mount Installation Guide that comes with the Ceiling
Mount Kit for more information. To turn the image upside
down, see “Ceiling” on page 38. The Ceiling Mount Kit is
sold separately; see page 52.

2 Position the projector the desired dist ance from the screen.

•

The distance from the lens of the projector to the screen
determines the size of the projected image. Figure 4 shows
three projected image sizes using the lens at minimum
focusing distance. For more information about image size,
see “Projected Image Size” on page 58.

NOTE: An optional extension
cable, sold separately, lets you
increase the distance between the
projector and your computer to
70 feet (21 m). See “Optional
Accessories” on page 52.

3 Make sure the projector and your computer are turned off.
