This device complies with part 15 of the FCC Rules. Operation is subj ect to the following two conditions: (1) This device may not cause ha rmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. § 15.21 Information to user. Any Changes or modifications not expressly approved by the party resp onsible for compliance could void the user's authority to operate the equipment. § 15.105 Information to the user. Note: This equipment has been tested and found to comply with the lim its for a Class B digital device, pursuant to part 15 of the FCC Rule s. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment g enerates uses and can radiate radio frequency energy and, if not inst alled 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 th is equipment does cause harmful interference to radio or television r eception, 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 tha t to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help.

RF Exposure evaluation According to KDB 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Worse case is as below: [697.8 MHz, 2.8dBm（1.91 mW） output power] (1.91mW /5mm) ·[√0.6978 (GHz)]= 0.32 <3.0 for 1-g SAR Then SAR evaluation is not required
