Where to install 
Never place the device in direct sunlight. Place it on a sturdy platform of which the 
surface should be flat and steady, so the product can’t fall or hit by any objects. Make 
sure the product is placed in such a manner that nothing can fall on top of it, as 
pressure will damage or break the product. Prevent insertion of objects into the 
ventilation slots, or openings in the cabinet at all time.
