Epson PowerLite EB-810E User Manual page 315

• If you are using the projector at altitudes above 4,921 feet (1,500 m), enable the High Altitude Mode
setting in the projector's menu to ensure the projector's internal temperature is regulated properly.
• Do not use the projector outside of the required temperature range below (20 to 80% humidity, no
condensation):
32 to 104 °F (0 to 40 °C) at an altitude of 7500 feet (2286 m) or less, or 32 to 95 °F (0 to 35 °C) at an
altitude of 7500 to 10000 feet (2286 to 3048 m)
Doing so may cause an unstable display and could lead to projector damage. Do not use or store the
projector where it may be exposed to sudden changes in temperature.
• Do not store the projector outside of the required temperature range of 14 to 140 °F (–10 to 60 °C) or
in direct sunlight for long periods of time. Doing so may cause damage to the case.
• Do not place anything that can become warped or damaged by heat near the exhaust vents. Do not
bring your hands or face close to the vents while projection is in progress. Do not bring your face close
to the projector while it is in use.
• Before you move the projector, make sure its power is turned off, the plug is disconnected from the
outlet, and all cables are disconnected. Fire or electric shock may result.
• Do not place the source of an open flame, such as a lit candle, on or near the projector.
• During projection, do not block the light from the projector with a book or other objects. If the light from
the projector is blocked, the area on which the light shines becomes hot which could cause it to melt,
burn, or start a fire. Also, the lens may get hot due to the reflected light which could cause the
projector to malfunction. To stop projection, use the A/V Mute function, or turn off the projector.
• Do not modify the power cord. Do not place heavy objects on top of the power cord or bend, twist, or
pull it excessively. Keep the power cord away from hot electrical appliances. Do not tie the power cord
to other cables. Do not use the power cord if it is damaged. Fire or electric shock may result. Contact
your dealer if the cable becomes damaged.
• Make sure you keep a distance of at least 7.9 inches (20 cm) between the device and your body.
Otherwise, it could cause you to feel unwell.
• Always lower the volume before turning off the projector. Turning on the projector with the volume too
high can damage your ears. Gradually increase the volume after turning on the projector.
• Incorrect battery usage may cause leakage of battery fluid and battery rupture, which could result in
fire, injury, or corrosion. When replacing batteries, take the following precautions: insert batteries so
that the polarities (+ and -) are correct; do not use batteries of different types or mix old and new
batteries; do not use any batteries other than those specified in this manual; if batteries leak, wipe
away battery fluid with a soft cloth and replace them with new batteries; if battery fluid gets on your
hands, wash them immediately; replace the batteries as soon as they run out; remove the batteries if
you will not be using the projector for a long period of time; do not expose batteries to heat or flame
