Safety and warranty guide
Inspect your device for dust accumulation at least once every three months. Before
inspecting your device, turn off the power and unplug the device’s power cord from
the electrical outlet; then remove any dust from vents and perforations in the bezel.
If you notice external dust accumulation, then examine and remove dust from the
inside of the device including heat sink inlet fins, power supply vents, and fans.
Always turn off and unplug the device before opening the cover. If possible, avoid
operating your device within 2 feet of high-traffic areas. If you must operate your
device in or near a high-traffic area, inspect and, if necessary, clean your device
more frequently.
For your safety and to maintain optimum device performance, always follow these
basic precautions with your device:
• Keep the cover closed whenever the device is plugged in.
• Regularly inspect the outside of the device for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent
cleanings might be required for device in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not store or operate your device inside furniture, as this might increase the
risk of overheating.
• Airflow temperatures into the device should not exceed 35°C (95°F).
• Do not use non-desktop air filtration devices.
Operating environment
The optimal environment in which to use your device is 10°C-35°C (50°F-95°F) with
humidity ranging between 35% and 80%. If your device is stored or transported
in temperatures less than 10°C (50°F), allow the cold device to rise slowly to an
optimal operating temperature of 10°C-35°C (50°F-95°F) before use. This process
could take two hours in extreme conditions. Failure to allow your device to rise to
an optimal operating temperature before use could result in irreparable damage to
your device.
If possible, place your device in a well-ventilated and dry area without direct
exposure to sunshine.
Keep electrical appliances such as an electric fan, radio, high-powered speakers,
air conditioner, and microwave oven away from your device because the strong
magnetic fields generated by these appliances can damage the monitor and data
on the hard disk drive.
