will not occur in a particular installation. If this
equipment does cause interference to radio or
television equipment reception, which can be
determined by turning the equipment offand on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna
-Move the equipment away from the receiver
-Plug the equipment into an outlet on a circuit different from that to which
the receiver is connected
-Consult the dealer or an experienced radio/television technician for
additional suggestions
You are cautioned that any change or modifications to the equipment not
expressly approve by the party responsible for compliance could void Your
authority to operate such equipment.
This device complies with Part 15 of the FCC Rules. Operation is subjected to
the following two conditions 1) this device may not cause harmful interference
and 2) this device must accept any interference received, including interference
that may cause undesired operation.

CPU Speed Setup
The system bus speed is depended on CPU. (Supported 100,133MHz). The user can change
the DIP switch(SW1) and Jumper (JP9) selection to set up the CPU speed for 600MHz–1GHz
processor.
M The CPU speed must match with the frequency ratio. It will cause system hanging up if
the frequency ratio is higher than that of CPU.
