Please read the following safety instructions carefully. It is advised that
you keep this manual for future references
1. All cautions and warnings on the device should be noted.
2. Make sure the power source matches the power rating of the
device.
3. Position the power cord so that people cannot step on it. Do
not place anything over the power cord.
4. Always completely disconnect the power before working on the
system’s hardware.
5. No connections should be made when the system is powered
as a sudden rush of power may damage sensitive electronic
components.
6. If the device is not to be used for a long time, disconnect it from
the power supply to avoid damage by transient over-voltage.
7. Always disconnect this device from any AC supply before
cleaning.
8. While cleaning, use a damp cloth instead of liquid or spray
detergents.
9. Make sure the device is installed near a power outlet and is
easily accessible.
10. Keep this device away from humidity.
11. Place the device on a solid surface during installation to prevent
falls
12. Do not cover the openings on the device to ensure optimal heat
dissipation.

13. Watch out for high temperatures when the system is running.
14. Do not touch the heat sink or heat spreader when the system is
running
15. Never pour any liquid into the openings. This could cause fire or
electric shock.
16. As most electronic components are sensitive to static electrical
charge, be sure to ground yourself to prevent static charge
when installing the internal components. Use a grounding
wrist strap and contain all electronic components in any static-
shielded containers.
17. If any of the following situations arises, please the contact our
service personnel:
i. Damaged power cord or plug
ii. Liquid intrusion to the device
iii. Exposure to moisture
iv. Device is not working as expected or in a manner as described
