Heat Sources -
Do not install the unit near any heat sources such as radiators, heaters,
stoves, or other equipment (including amplifiers) that produce heat.
2.
Ventilation -
Any openings in the unit enclosure are provided for ventilation to prevent
overheating and ensure reliable operation. Do not block or cover these openings. Do not
place the unit in an enclosure unless proper ventilation is provided, or the manufacturer's
instructions have been adhered to.

laundry basket, in a damp or wet basement, near a swimming pool, in an outdoor
installation, or in any area classified as a wet location. To reduce the risk of fire or
electrical shock, do not expose this unit to rain or moisture.

Object and liquid entry -
Never push objects of any kind into this unit through openings
as they may touch dangerous voltage points or short-out parts that could result in a fire
or electrical shock. Never spill liquid of any kind on the unit. Do not place objects filled
with liquids, such as vases or cups, on the unit.
5.
Lightning -
