Safety information

Electrical safety

•  To prevent electric shock hazard, disconnect the power cable from the electric outlet 

before relocating the system.

•  When adding or removing devices to or from the system, ensure that the power cables 

for the devices are unplugged before the signal cables are connected. If possible, 

disconnect all power cables from the existing system before you add a device.

•  Before connecting or removing signal cables from the motherboard, ensure that all 

power cables are unplugged.

•  Seek professional assistance before using an adapter or extension cord. These devices 

could interrupt the grounding circuit.

•  Ensure that your power supply is set to the correct voltage in your area. If you are not 

sure about the voltage of the electrical outlet you are using, contact your local power 

company.

•  If the power supply is broken, do not try to fix it by yourself. Contact a qualified service 

technician or your retailer.

•  The optical S/PDIF is an optional component (may or may not be included in your 

motherboard) and is defined as a CLASS 1 LASER PRODUCT.

INVISIBLE LASER RADIATION, AVOID EXPOSURE TO BEAM.

•  Never dispose of the battery in fire. It could explode and release harmful substances into 

the environment.

•   Never dispose of the battery with your regular household waste. Take it to a hazardous 

material collection point.

•  Never replace the battery with an incorrect battery type.

•  RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
•  DISPOSE OF USED BATTERIES ACCORDING TO THE ABOVE BATTERY-RELATED 

INSTRUCTIONS.

Operation safety

•  Before installing the motherboard and adding devices on it, carefully read all the manuals 

that came with the package.

•  Before using the product, ensure that all cables are correctly connected and the power 

cables are not damaged. If you detect any damage, contact your dealer immediately.

•  To avoid short circuits, keep paper clips, screws, and staples away from connectors, 

slots, sockets and circuitry.

•  Avoid dust, humidity, and temperature extremes. Do not place the product in any area 

where it may become wet.

•  Place the product on a stable surface.
•  If you encounter technical problems with the product, contact a qualified service 

technician or your retailer.
