FCC ID : 2BW2S-EZPEN2PP LABELLING REQUIREMENTS Labelling Requirements Since the product is so small size, the 15.19(a)(3) statement is placed in the manual. § 15.19 (a)(5) Labeling requirements: When the device is so small or for such use that it is impracticable to label it with the statement specified under paragraph (a) of this section in a font that is four-point or larger, and the device does not have a display that can show electronic labeling, then the information required by this paragraph shall be placed in the user manual and must also either be placed on the device packaging or on a removable label attached to the device.

July 15, 2026 Project No.: NK-26-R-126 FCC Certification MEVERTEC Inc. FCC ID : 2BW2S-EZPEN2PP Page 1 of 1 Maximum Permissible Exposure RF Exposure Limit According to KDB 447498D01 v06: The 1g and 10g 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)] ꞏ[√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 The test exclusions are applicable only when the minimum test separation distance is ≤50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is <5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Device category : Portable device Transmitting mode : Single transmitting Max. transmitting frequency : 2 480 MHz Min. test separation distance : 5 mm Max. Antenna Gain : 3.3 dBi Max. Average power : -3.59 dBm Max. power with turn-up tolerance : -3.5 dBm 0.45 mW Maximum Permissible Exposure For this device: 0.45 mW[maximum average output power]/5 mm[minimum separation distance] x √2.48 GHz = 0.71 Note. The calculation result was rounded to one decimal place for comparison. Test Result : This is less than 3.0 for 1-g SAR. SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required.
