Well-Ventilated Location
There are inlet holes on the bottom side of the instrument. In addition, there are vent
holes for the cooling fan on the rear panel. To prevent internal overheating, allow for
enough space around the instrument (see the figure below) and do not block the inlet
and vent holes.
Provide adequate space around the GS820.
