1.1 General safety matters
To prevent the risk of major personal and property losses, please follow the following
recommendations.
Please do not open the system cover by yourself, and should be operated by
professionally trained maintenance technicians. There may be high voltage or electric
shock on the triangular mark with lightning symbol, please do not touch it.
Remember: Disconnect all cables before performing maintenance. (There may be more
than one cable) It is strictly forbidden to perform live operations such as starting the
machine before the cover is closed.
When it is necessary to open the cover, please wait for the internal equipment to cool
down before performing it, otherwise it is easy to burn you.
Do not use this device in a humid environment.
If an extension cable needs to be used, please use a three-wire cable and make sure it
is properly grounded.
Ensure that the computer is well grounded. Different grounding methods can be used,
but it must be actually connected to the ground. If you are not sure whether the
grounding protection has been secured, please contact the corresponding agency or
electrician for confirmation. If you need twisting table cable wiring, please contact
QTECH to provide suggestions.
Please use a three-core power cord and socket with grounding protection. Improper
grounding may cause leakage, burns, explosions and even personal injury.
Please make sure that the power socket and the power interface can be in close
contact, loose contact may cause a fire hazard.
Please use your computer under 220V AC voltage. Working at an improper voltage will
cause electric shock, fire and computer damage.
The computer is required to be well ventilated and far away from heat and fire sources,
and do not block the cooling fan, otherwise the computer may cause smoke, fire or
other dangers due to overheating.
If you smell or see smoke from your computer, please turn off the computer
immediately and unplug the power cord.
It is required to be able to easily plug and unplug the power cord from the power source
and the power socket. Please keep the power cord and plug clean and intact, otherwise
there may be a risk of electric shock or fire.
Note: If the battery is replaced incorrectly, there is a danger of explosion. Only use the
same or equivalent type of replacement recommended by the manufacturer. The used
battery will pollute the environment. Please follow the relevant instructions for the
replacement of the old battery.
Keep the computer away from electromagnetic fields.
