[. . . ] These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used 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 harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ?

The receiver header consists of a filtered translated infrared input compliant with Microsoft CIR specifications and a ?learning?The learning input is a high-pass input which the computer can use to ?learn?to speak the infrared communication language of other user remotes. The emitter header consists of two output ports which the computer can use to emulate ?learned?infrared commands in order to control external electronic hardware. NOTE The Consumer IR option must be enabled in the system BIOS before it can function. Press <F2> at boot to enter the system BIOS, and go to Advanced > Peripheral Configuration > Enhanced Consumer IR, and set this option to Enabled. Table 6 shows the pin assignments and signal names for the front panel CIR receiver (input) header and Table 7 shows the pin assignments and signal names for the back panel CIR emitter (output) header.

CAUTION Failure to use an appropriate power supply and/or not connecting the 12 V (Figure 30, A) power connector to the Desktop Board may result in damage to the board or the system may not function properly. The 2 x 12 pin main power connector (Figure 30, D) is backwards compatible with ATX12V power supplies with 2 x 10 connectors. Use of the 1 x 4 auxiliary PCI Express graphics power connector (Figure 30, C) or the SATA-style auxiliary power connector (Figure 30, B) is required with ATX12V power supplies when using PCI Express graphics cards that can consume up to 75 W. Figure 30. Connecting Power Supply Cables 54 Installing and Replacing Desktop Board Components 1. Observe the precautions in "Before You Begin" on page 27. Connect the 12 V processor core voltage power supply cable to the 2 x 4 pin connector. Connect the main power supply cable to the 2 x 12 pin connector. If additional power is required, connect the appropriate power supply cable to either the 1 x 4 auxiliary PCI Express graphics power connector or to the SATAstyle auxiliary PCI Express graphics power connector or to both. Setting the BIOS Configuration Jumper NOTE Always turn off the power and unplug the power cord from the computer before moving the jumper. Moving the jumper with the power on may result in unreliable computer operation. Figure 31 shows the location of the Desktop Board?s BIOS configuration jumper block. Figure 31. Location of the BIOS Configuration Jumper Block The three-pin BIOS jumper block enables all board configurations to be done in the BIOS Setup program. [. . . ] If this is used near a radio or television receiver in a domestic environment, it may cause radio interference. Install and use the equipment according to the instruction manual. 82 Regulatory Compliance Korean Class B statement translation: This is household equipment that is certified to comply with EMC requirements. You may use this equipment in residential environments and other non-residential environments. Ensure Electromagnetic Compatibility (EMC) Compliance Before computer integration, make sure that the power supply and other modules or peripherals, as applicable, have passed Class B EMC testing and are marked accordingly. Pay close attention to the following when reading the installation instructions for the host chassis, power supply, and other modules: ? [. . . ]
