∙Make sure that the power voltage is within its safety range and has been adjusted
properly to the value of 100~240V before connecting the device to the power outlet.
∙If the power cord comes with a 3-pin plug, do not disable the protective earth pin
from the plug. The device must be connected to an earthed mains socket-outlet.
∙Please confirm the power distribution system in the installation site shall provide
the circuit breaker rated 120/240V, 20A (maximum).
∙Always disconnect the power cord or switch the wall socket off if the device would
be left unused for a certain time to achieve zero energy consumption.
∙Place the power cord in a way that people are unlikely to step on it. Do not place
anything on the power cord.
∙If this device comes with an adapter, use only the MSI provided AC adapter approved
for use with this device.
Environment
∙To reduce the possibility of heat-related injuries or of overheating the device, do not
place the device on a soft, unsteady surface or obstruct its air ventilators.
∙Use this device only on a hard, flat and steady surface.
∙To prevent the device from tipping over, secure the device to a desk, wall or fixed
object with an anti-tip fastener that helps to properly support the device and keep it
safe in place.
∙To prevent fire or shock hazard, keep this device away from humidity and high
temperature.
∙Do not leave the device in an unconditioned environment with a storage temperature
above 60℃ or below -20℃, which may damage the device.
∙The maximum operating temperature is around 40℃.
∙When cleaning the device, be sure to remove the power plug. Use a piece of soft
cloth rather than industrial chemical to clean the device. Never pour any liquid into
the opening; that could damage the device or cause electric shock.
∙Always keep strong magnetic or electrical objects away from the device.
