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. 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. Modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment under FCC rules.

According to KDB 447498 D01 General RF Exposure Guidance v06, section 4.3.1 A t 100 ㎒ to 6 ㎓ and for test separation distances ≤ 50 mm, the SAR test exclusion threshold is determined according to the following; a) [(max. power of channel, including tune-up tolerance, ㎽) / (min. test separation distance, mm)] x [√f(GHz)] ≤ 3.0 1. SAR test exclusion threshold Frequency : 2402 ㎒ (min. separation distances = 5 mm) SAR test exclusion thresholds(5 mm) = [(2.723 / 5) * √2.440] = 0.85 < 3.0. Mode Frequency (MHz) Measured max output Power (mW) Separation Distance (mm) ≤ 3.0 Bluetooth24402.72350.85 2. Conclusion : Bluetooth SAR was not required SAR test exclusion
