electrical safety
●
All instructions for use and installation must be carried out in accordance with the electrical safety
regulations of your country.
●
The power supply must comply with the Safety Low Voltage (SELV) standard and supply
power with a nominal voltage that meets the limited power source requirement in
accordance with IEC60950-1. Power supply requirements are indicated on the device label.
● Make sure the power supply is adequate before using the device.
●
An easily accessible disconnect device must be incorporated into the building installation
wiring.
●
Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the device.
operating environment
●
Do not point the device directly at strong light when focusing, such as lamplight and
sunlight; otherwise, it may cause excessive brightness or light streaks, which will not be
caused by device malfunction and may affect the life of the complementary metal oxide
semiconductor (CMOS).
●
Do not place the device in a humid, dusty, extremely hot or cold environment, or in
places with strong electromagnetic radiation or unstable lighting.
●
Keep the device away from any liquid to prevent damage to internal components.
●
Please keep the indoor device away from rain or moisture to avoid fire or lightning.
●
Maintain good ventilation to prevent heat buildup.
●
Transport, use and store the device within the permissible limits of humidity and
temperature.
●
Do not subject the unit to high pressure, strong vibration, or splashing water during
transportation, storage, and installation.
● When transporting the device, store it in the factory package or use equivalent
materials.
●
Install the device in a place that can only be accessed by professional personnel with
relevant knowledge of safety protections and warnings. Failure to do so may cause
damage to non-professionals entering the installation area when the device is operating
normally.
Use and daily maintenance
●
Do not touch the heat dissipation component of the device to avoid burns.
