Maximum Permissible Exposure 2.1 RF Exposure calculation According to the FCC rule §1.1310 the limit for General Population/Uncontrolled exposure is 1 ㎽/㎠ for the device operating 1 500 ㎒ ~ 100 000 ㎒. Kind of EUT 50S Operating Frequency Band □ WLAN(802.11b/g/n(HT20)): 2 412 ㎒ ~ 2 462 ㎒ □ WLAN(802.11n(HT40)): 2 422 ㎒ ~ 2 452 ㎒ □ WLAN: 5 180 ㎒ ~ 5 320 ㎒ / 5 500 ㎒ ~ 5 700 ㎒ □ WLAN: 5 745 ㎒ ~ 5 825 ㎒ ■ Bluetooth: 2 402 ㎒ ~ 2 480 ㎒ Max.
