EUT Specification Product Name: TPMS Trade Mark: Malide Model/Type Reference: MLD-B22 Listed Model(s): MLD-B22D Model Differences: These models are identical in printed circuit board, electrical layout and circuitry; they differ only in model designation. Frequency Band (Operating) BLE: 2402MHz ~ 2480MHz Device Category Portable (<5mm separation) Mobile (>20cm separation) Fixed (>20cm separation) Others ___ Exposure Classification Occupational/Controlled exposure (S=5mW/cm 2 ) General Population/Uncontrolled exposure (S=1mW/cm 2 ) Antenna Diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Antenna Gain (Max) BLE: 1.05dBi Evaluation Applied MPE Evaluation SAR Evaluation Page 2 of 2 Report No.: CTC2026406903 CTC Laboratories, Inc.

If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. Measurement Result Mode Frequency (MHz) Antenna Gain (dBi) Maximum Power (dBm) Max. Tune Up Power (dBm) Power Density at 20cm (mW/cm 2 ) Limit (mW/cm 2 ) BLE 2402 1.05 5.32 6 0.001009 1 Note: 1. Calculate in the worst-case mode. 2. Max. Tune Up Power is declared by manufacturer, and used to calculate. 3.
