the manufacturer.
 Dispose of used batteries according to the battery
manufacturers instructions.
Joystick or MIDI port:  Do not use any joystick or MIDI device that requires more than
10A current at 5V DC . There is a risk of fire for devices that exceed this limit.
FCC and DOC Statement on Class B
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to tr y to correct the interference by one or more of the following measures:
 Reorient or relocate the receiving antenna.  Increase the separation between the equipment and the receiver.  Connect the equipment into an outlet on a circuit different from

We recommend that you use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An ATX12V power supply has a standard 20-pin ATX main power connector, a 4-pin +12V power connector and a 6-pin auxiliary power connector that must be inserted onto PL1, ATXP1 and ATXP2 connectors respectively.

The 4-pin +12V power connector enables the delivery of more +12VDC current to the processors Voltage Regulator Module (VRM).
The 6-pin auxiliary power connector provides additional current for the boards +3.3VDC and +5VDC. Using a power supply that does not have this connector will still provide power as long as the 20-pin ATX main power and 4-pin +12V power are connected.
The system board requires a minimum of 250 Watt power supply to operate. Your system configuration (amount of memory, add-in cards, peripherals, etc.) may exceed the minimum power requirement. To ensure that adequate power is provided, use a 300 Watt (or greater) power supply.
