FCC Information to User This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. 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: — Reorient or relocate the receiving antenna. — Increase the separation between the equipment and receiver. — Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. — Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE: FCC RF Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

FCC ID: RVBXPG300YN * SAR evaluation - Min. transmitting frequency = 2402 MHz - Min. test separation distance = 5 mm -Max. Power with tune-up tolerance = 2.04 dBm = 1.6 mW (Measured Maximum power = 1.54 dBm ± 0.5dB) Step 1) SAR Test exclusion thresholds for 100MHz to 6GHz at test separation distance ≤ 50 mm = Used [(max.power of channel, including tune-up torelance, mW)/(min. test separation distance, mm)] * [√f(GHz)] = [ 1.6 / 5 ] * [ √ 2.402 ] = 0.496 ≤ 3, for 1g SAR Thus, SAR for this device is not required. Step 2) SAR Test exclusion thresholds for 100MHz to 1500MHz at test separation distance > 50 mm = N/A [Threshold at 50mm in step 1) + (test separation distance - 50 mm) * (√f(MHz)/150] mW Step 3) SAR Test exclusion thresholds for 1500MHz to 6GHz at test separation distance > 50 mm = N/A [Threshold at 50mm in step 1) + (test separation distance - 50 mm) * 10] mW
