in accordance with the instructions, 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 interference to radio or

television equipment reception, which can be
determined by turning the equip ment off and 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 selectable at 66,100,133MHz and Auto. The user can select the
system bus speed (SW1) and change the DIP switch (SW2) selection to set up the CPU speed

for 500MHz – 1GHz and above processor.

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.

Note:

1. If you use 66, 100, 133 MHz CPU, we recommend you to set up your system speed to
“Auto” value.

2. We don’t recommend you to set up your system speed to 75,83,112, 124, 140,150 MHz
because these frequencies are not the standard specifications for CPU, Chipset and

most of the peripherals. Whether your system can run under 75,83,112, 124, 140,150
MHz properly will depend on your hardware configurations: CPU, SDRAM, Cards, etc.

Dolby digital decoder). In general, Line Out 1 is

normally Line Out, when it output digital signal, it will
be change to SPDIF Out automatically (see page 45

for more information).
Line In: In general, Line In is normally Line In. When
you select “Four Speaker” in Creative application

(see page 42 for more information), Line In will be
