Using a cross-tip screwdriver, remove the four screws from the back cover. Remove the cover from the unit. Set the cover and screws aside. WL-463 guide.fm Page 2 Tuesday, November 18, 2003 3:48 PM 3Remove the antenna housing. Grasp the inside edge of the antenna housing and pull up to disengage the housing from the unit, as shown below. This part is no longer needed. 4Install the radio board. Holding the radio board at an angle, align the contact edge with the mini PCI connector on the unit. Make sure the keying notch on the contact edge lines up with the key on the connector, as shown in the detail below. Slide the board into the connector and press down gently until the two retainer clips snap into place. WL-463 guide.fm Page 3 Tuesday, November 18, 2003 3:48 PM 5Attach the cables to the antenna module. With the notched side of the square connector facing up (button side facing down), insert one cable connector into the B1 connection on the antenna module and push gently until it snaps into place. Attach the other cable connector to the B2 connection in the same manner. 6Attach the antenna module and connect the cables. 1Align the antenna module with the snaps and posts on the unit and press until the module snaps firmly into place. Make sure the cables are routed through the slots in the unit. 2Align the free end of one cable with one connector on the board. Press until the cable snaps into place. Repeat with the other cable and the other connector. (You can connect either cable to either connector; the order is not important.) 3After the cables are connected, press them down out of the way inside the housing. WL-463 guide.fm Page 4 Tuesday, November 18, 2003 3:48 PM 7Replace the back cover. Make sure that the cables are tucked away inside the housing so that they do not obstruct the cover. Align the back cover with the unit and settle the cover into place. Tighten the four screws. 8Attach the antennas. Being careful not to touch the antenna tips, screw the antennas onto the SMA connectors and hand tighten them. After network startup, you may need to adjust the antennas to fine tune radio coverage. 9Reinstall the access point. Reconnect the Ethernet cable and reattach the access point to the wall mounting plate. Adjust the antennas to improve the radio signal, if necessary.

FCC ID: HEDWL463ACC ADT No.: 921008H03 RF EXPOSURE REPORT REPORT NO.: RF921008H03 MODEL NO.: WL-463 ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT: Accton Technology Corporation ADDRESS: No.1, Creation Rd. III, Science-based Industrial Park, Hsinchu, Taiwan, R.O.C. ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Lab Code: 200376-0 FCC ID: HEDWL463ACC ADT No.: 921008H03 RF Exposure Measurement 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: HEDWL463ACC ADT No.: 921008H03 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4 EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification The antenna of this product, under normal use condition, is at least 20cm away from the body of the user.
