Introduction

The DLP Pico Projector is a convenient, versatile, state-of-the-art presentation system.
It is an effective and valuable tool for projecting computer-generated video
information or full motion video signals onto a front or rear projection screen. The

files, Powerpoint presentations and various video files directly from the Pico
Projector without the need for external signal sources. This, coupled with the
rechargeable battery, allows easy presentations on the fly. The Pico Projector is an
ideal companion to travelling executives, sales personnel and anyone who wants to
do presentations and entertainment on the spot. Photos and videos can easily be
shared in group meetings or parties. Apps can be downloaded to extend the
applications of the Pico Projector. For some Smartphones, wireless projection can
be done via DLNA or Miracast broadening the connectivity of this Pico Projector.

Care and Maintenance

The information in this chapter describes how to care for and prevent accidental
damage to your Pico Projector. You should treat your Pico Projector with the
same care you would give to any other valuable equipment.

Cleaning the Pico Projector Housing

DO NOT try to service the Pico Projector. Refer all Pico Projector servicing to

your dealer. Failure to do so can result in serious personnel injury or damage to
the Pico Projector.

DO NOT clean the housing with organic solvents, such as those containing
acetone. Wipe the exterior of the housing with a soft, damp cloth. Protect the
Pico Projector from rain, snow or extreme temperature.

Cleaning the Projection Lens

To clean the projection lens:
Use a cotton-bud stick to gently wipe dust or oil from the projection lens surface.
Also, do not use abrasive cleaners, solvents, or other harsh chemicals that might
scratch the lens.

Transporting the Pico Projector

The DLP Pico Projector is a highly sophisticated piece of electronic equipment
that is sensitive to impact, excessive heat, cold and humidity. When transporting
the Pico Projector, use a protective bag or use the original packing carton to

20

minimize shock and impact.

Store and transport the Pico Projector at temperature between 0 and 140 degrees
Fahrenheit (-17 to 60 degrees Centigrade). Avoid storage in automobiles during
seasonal temperature extremes. Automobile interior temperatures can exceed
160 degree Fahrenheit (70 degrees Centigrade) in summer. If the Pico Projector
has been exposed to extremely hot, cold or humid conditions, allow it to stand at
room temperature for 30 minutes before use. Extended use of the Pico in high
temperature environments may cause a reduction in brightness of the projected
image.

Troubleshooting Guide

If you are having a problem operating the Pico Projector, first make sure you
have set it up according to the Section on Setting Up your Pico Projctor. You
should also check the adjustments and the INPUT connections. Verify that all
power is switched on. Before calling for service, check the troubleshooting
suggestions in this Section.

Problem Solutions
