Cleaning the vents
As a general rule, use a vacuum cleaner about once a
month to clean the vents on the rear panel of the display
of dust buildup (set the vacuum cleaner to its weakest
setting when doing this).
Using the unit without cleaning it of dust will cause the
internal temperature to increase, resulting in possible
breakdown or fire.
