Note: 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

RF Exposure Requirements Product Description: Long Remote Control Model No.: 18-KEY FCC ID: 2BOYX-18KEY Tx frequency: 433.92 MHz Type of Modulat ion: OOK Antenna Type: PCB Antenna Nominal rated field strength: 75.87 dBμV/m at 3 meter Based on the Maximum allowed field strength was 75.87 dBμV/m at 3m in frequency 433.92 MHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.0116 mW According to the FCC Part 1.1307(b)(3)(i)(A) and KDB 447498 D04v01, a single RF source is exempt RF device if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
