Cleaning the lters
Dene XL R2 is equipped with two particle lters at air intakes to prevent dust from entering
the case. To ensure optimal cooling, lters should be cleaned on a regular basis.
• To clean the PSU lter, simply slide the lter toward the rear of the case and remove
it; clean any dust gathered on it.
• To clean the front lter, open the front door panel and push the symbols on the hatch
to open the fan door. To completely remove fan lter, pull down the lever on the top of
the lter. Once removed, the lter can then be cleaned directly by hand or with water if
fans have been removed.

Power/HDD LED activity
Dene XL R2 features an LED on the front panel that, when lit, indicates the computer is
receiving power. By changing its connection on the motherboard, the LED can be used to
indicate HDD activity. In either case, connecting the LED to the motherboard is optional;
computer functionality is not dependent on its connection.
