Safety Precautions
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.
