• Do not block the openings of the cabinet. Leave at least 20 cm of space above and 10 cm
to the sides of the PBX for ventilation.
• Make sure that the wall behind the cabinet is flat and free of obstacles, so that the openings
on the back of the cabinet will not be blocked.
• Be careful not to drop the cabinet.
