EverFocus EMD935F User Manual page 2

1. Do not install the camera near electric or magnetic fields. Install the camera away from
TV/radio transmitters, magnets, electric motors, transformers and audio speakers since the
electromagnetic fields generated from these devices may distort the video image or
otherwise interfere with camera operation.
2. Never disassemble the camera beyond the recommendations in this manual nor introduce
materials other than those recommended herein. Improper disassembly or introduction of
corrosive materials may result in equipment failure or other damage.
3. Try to avoid facing the camera toward the sun. In some circumstances, direct sunlight may
cause permanent damage to the sensor and/or internal circuits, as well as creating
unbalanced illumination beyond the capability of the camera to compensate.
4. Keep the power cable away from water and other liquids and never touch the power cord
with wet hands. Touching a wet power cord with your hands or touching the power cord
with wet hands may result in electric shock.
5. Never install the camera in areas exposed to oil, gas or solvents. Oil, gas or solvents may
result in equipment failure, electric shock or, in extreme cases, fire.
6. Cleaning. For cameras with interchangeable lenses, do not touch the surface of the sensor
directly with the hands. Use lens tissue or a cotton tipped applicator and ethanol to clean
the sensor and the camera lens. Use a damp soft cloth to remove any dirt from the camera
body. Please do not use complex solvents, corrosive or abrasive agents for cleaning of any
part of the camera.
7. Do not operate the camera beyond the specified temperature, humidity or power source
ratings. This camera is suitable for indoor operation only. Use the camera at temperatures
within ‐10°C~50°C (‐14°F~122°F) and humidity less than 80%; this device is not rated as
submersible. The input power source is 12VDC. Be sure to connect the proper + / ‐ polarity
and voltage, as incorrect polarity or too high a voltage will likely cause the camera to fail,
and such damage is not covered by the warranty.
8. Mounting. Use care in selecting a solid mounting surface which will support the weight of
the camera plus any wind, snow, ice or other loading, and securely attach the camera to the
mounting surface using screws and anchors which will properly support the camera. If
necessary (e.g. when mounting to drop ceilings) use a safety wire to provide additional
support for the camera.
