damage.
• When turning on the projector, make sure no one within projection range is looking into the lens.
• Follow all installation, operation, adjustment, and maintenance procedures to avoid possible
exposure to hazardous laser radiation.
Batteries precautions
Read the following precautions for your battery:
Caution! If not avoided, the following could result in minor or moderate injury.
• Keep new and used batteries away from children.
• Discontinue usage if leakage is found.
• EXPLOSION HAZARD! Dispose of the battery according to local area regulations.
Warning! If not avoided, the following could result in death or serious injury.

3D safety information
Follow all recommended warnings and precautions before using the 3D function.
Caution! If not avoided, the following could result in minor or moderate injury.
• Closely supervise children and teenagers viewing 3D images as they may be more susceptible to
health issues associated with them.
Photosensitive seizure warning and other health risks
Some viewers may experience discomfort when exposed to certain flashing images or lights contained
in certain projector pictures or video games.

Introduction
Sonnoc User Manual

• Some viewers may experience an epileptic seizure or stroke when exposed to certain flashing
images or lights contained in certain projector pictures or video games. If you suffer from, or
have a family history of epilepsy or strokes, consult with a medical specialist before using the
3D function. Those without a personal or family history of epilepsy or stroke may have an
undiagnosed condition that can cause photosensitive epileptic seizures.
• Pregnant women, the elderly, sufferers of serious medical conditions, those who are sleep
deprived, or those under the influence of alcohol should avoid using the 3D functionality.
• If experiencing any of the following symptoms, stop viewing 3D pictures immediately and
consult a medical specialist:
• Altered vision
• Lightheadedness
• Dizziness
• Involuntary movements such as eye or muscle twitching
• Confusion
• Nausea
• Loss of awareness
• Convulsions
• Cramps
• Disorientation
Children and teenagers may be more likely than adults to experience these symptoms. Monitor
children and ask if they are experiencing these symptoms.
• Watching 3D projection may also cause motion sickness, perceptual after effects,
disorientation, eye strain and decreased postural stability. Sonnoc recommends taking frequent
breaks to lessen the potential of these effects. If your eyes show signs of fatigue or dryness or
if experiencing any of the above symptoms, immediately discontinue use of this device and do
not resume using it for at least thirty minutes after the symptoms have subsided.
• Watching 3D projection while sitting too close to the screen for an extended period of time may
damage your eyesight. The ideal viewing distance should be at least three times the screen
height. Sonnoc recommends the viewer’s eyes are level with the screen.
• Watching 3D projection while wearing 3D glasses for an extended period of time may cause a
headache or fatigue. If experiencing a headache, fatigue, or dizziness, stop viewing the 3D
projection and rest.
• Do not use the 3D glasses for any other purpose than for watching 3D projection.
• Wearing the 3D glasses for any other purpose (as general spectacles, sunglasses, protective
goggles, and so on) may be physically harmful to you and weaken your eyesight.
• Viewing in 3D projection may cause disorientation for some viewers. Do not place the 3D
projector near open stairwells, cables, balconies, or other objects that can be tripped over, run
into, knocked down, broken, or fallen over.

How the projector works
The Sonnoc Series projector accepts a variety of input signals for a wide range of commercial
projection applications.
Designed with solid-state illumination light sources and phosphor technology, the red, green and
blue color elements are segmented through a phosphor wheel and then modulated by one Digital
Micromirror Device (DMD) panel responding to incoming data streams of digitized red, green and
blue color information. As these digital streams flow from the source, light from the responding on
pixels of the DMD panel is reflected, converged and then projected to the screen through projection
lenses, where all pixel reflections are superimposed in sharp full-color images.
