Click the Next button. 8 Configuring the Router (continued) PPPoE/PPPoA Connections If you selected the PPPoE/PPPoA connection type in the previous window, you will see the Setup Wizard window pictured here. Type in the Username and Password used to identify and verify your account to the ISP. If you have been instructed to change the VPI number and VCI number, type in the new values. Select the Connection Type used for encapsulation specific to your service. Click Next when you are ready to continue to the Setup Completed window. Type the User Name and Password for your ISP account. Change the VPI and VCI numbers as instructed by your ISP. Type the new values in the spaces provided here. Select the Connection Type as instructed by your ISP. Click the Next button. Skip ahead to the Setup Completed window below. 9 Configuring the Router (continued) Dynamic IP Address Connections If you selected the Dynamic IP Address connection type, select the Connection Type used for encapsulation. If you have been instructed to change the VPI number and VCI number, type in the new values. Click Next when you are ready to continue the Setup Completed window. Note An option for Dynamic IP Address connections is to use the MAC address from your computer in place of the Router’s actual MAC address for the purpose of Address Resolution by the ISP’s DHCP server. To implement this feature click on the Clone MAC Address button before continuing to the next window. Change the VPI and VCI numbers as instructed by your ISP. Type the new values in the spaces provided here. Select the Connection Typeas instructed by your ISP. Click the Next button. Skip ahead to the Setup Completedwindow below. 10 Configuring the Router (continued) Static IP Address Connections If you selected the Static IP Address connection type, change the WAN IP Address, Subnet Mask, ISP Gateway Address, Primary DNS (Server IP) Address and (if available) Secondary DNS (Server IP) Address as instructed by your ISP. Select the Connection Type used for encapsulation. If you have been instructed to change the VPI number and VCI number, type in the new values. Click Ne…

Introduction The EUT operates in the 2.4GHz ISM band. Due to the EUT (include antenna) at its normal operation distance is at least 20 cm from the human body, the EUT was defined as a Mobile Device. The reason to do the MPE Evaluation is to avoid the RF hazard to human body. The maximum output power and gain of the antenna were used to calculate the limited Power density (S) at 20cm distance away from the product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. According to 1.1307 (b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. 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 30-300 61.4 0.163 1.0 6 300-1500 - - F/300 6 1500-100,000 - - 5 6 (B) Limits for General Population / Uncontrolled Exposure 30-300 27.5 0.073 0.2 30 300-1500 - - F/1500 30 1500-100,000 - - 1.0 30 F= Frequency in MHz FCC ID. : KA2SL2640T Report No.: EME-060497 Page 5 of 5 3. RF Exposure calculations From FCC 1.1310 table 1, the maximum permissible RF exposure for an uncontrolled environment is 1mW/(cm 2 ) Power density (S) is calculated by the following formula: S = (P * G)/4πR 2 where, S = Power density (mW/cm 2 ) P = Output power to antenna (mW) R = Distance between radiating structure and observation point (cm) G = Gain of antenna in numeric π = 3.1416 Example: Assume a mobile device operates at 2412MHz and its maximum output power is 50mW, and the maximum gain of antenna is 1 (numeric) /0dBi. then the power density (S) = (50 * 1)/4*π*20 2 = 0.00995 (mW/cm 2 ) 4. Test results Test Mode: 802.11b (DSSS Modulation) operating mode Channel Channel Frequency (MHz) Maximum antenna gain (numeric) Output power to antenna (mW) Power density (mW/cm 2 ) Limit of power density (mW/cm 2 ) 1 (lowest) 2412 1.58 61.940.01953 1.0 6 (middle) 2437 1.58 74.990.02364 1.0 11 (highest) 2462 1.58 57.940.18270 1.0 Test Mode: 802.11g (OFDM Modulation) operating mode Channel Channel Frequency (MHz) Maximum antenna gain (numeric) Output power to antenna (mW) Power density (mW/cm 2 ) Limit of power density (mW/cm 2 ) 1 (lowest) 2412 1.58 263.630.08312 1.0 6 (middle) 2437 1.58 325.090.10250 1.0 11 (highest) 2462 1.58 260.020.81984 1.0 The Notice in Installation Manual has been stated as below: While installing and operating this transmitter, the radio frequency exposure limit of 1mW/(cm*cm) may be exceeded at distances close to the transmitter. therefore, the user must maintain a minimum distance of 20 cm from the device at all time.
