XJ4KB6117SILICON BLUETOOTH KEYBOARD

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.

Except as shown in paragraph (c) of this section. if transmitting antennas of directional gain greater than 6 dBi are used. the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1). (b)(2). and (b)(3) of this section as appropriate. by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 1.1.2 EUT RF Exposure The Max Conducted Peak Output Power is -2.58dBm (0.552mW) at the lowest channel; The best case gain of the antenna is 2dBi. 2dBi corresponds to linear antenna gain : 1.58. According to the formula, the calculation the EIRP test result: EIRP= P x G = 0.552mW x 1.58= 0.872mW ① SAR requirement: S= 60 / f(GHz) = 60/2.402 = 144.12mW ② ; ① < ②. So the SAR measurement is not required.
