Prevent the power cable from being trampled or pressed, especially the plug, power socket and the
junction extruded from the device.
Environment
Do not aim the device at strong light to focus, such as lamp light and sun light; otherwise it might
cause over brightness or light marks, which are not the device malfunction, and affect the longevity
of Complementary Metal-Oxide Semiconductor (CMOS).
Do not place the device in a damp, dusty extremely hot or cold environment, or the locations with
strong electromagnetic radiation or unstable lighting.
Keep the device away from any liquid to avoid damage to the internal components.
Keep the indoor device away from rain or damp to avoid fire or lightning.
