Turning on B. Turning off Pairing Your Headset with a Bluetooth ® wireless technology enabled device 1. Turn on the Bluetooth ® function in the device. 2. Place the headset and the device where they are visible, within arm’s length from each other. 3. Ensure the headset is OFF. 4. To activate the device’s pairing mode, press and hold the MFB until the 5. Search the headset, select “UA-28SE” and enter the passcode “0000”. If your device supports “Simple Pairing” function, no code is required. Press and hold the MFB until the status indicator flashes blue. Press and hold the MFB until the status indicator flashes red. 12 Pairing Your Headset with Two Blue- tooth ® wireless technology enabled devices (Multi-point) UA-28SE supports a Multi-point function to allow simultaneous pairing of the headset with two devices. 1. Pair the headset with the first device (follow the step in “Pairing Your Headset with a Bluetooth wireless technology enabled device”). 2. Turn off the headset and the Bluetooth® function of the first paired device. 3. Pair the headset with the second device (follow the step in “Pairing Your Headset with a Bluetooth wireless technology enabled device”). 4. Activate the Bluetooth connection with the headset and the first paired device on the device’s menu. • For some devices, you may need to manual press “connect” to connect the headset. • If the pairing cannot be completed within two minutes, the headset will auto- matically go to standby mode and then turn off after five minutes. Repeat steps to pair both devices again. 13 Reconnecting Your Headset 1. If the headset has been powered off, it will reconnect to the phone auto- matically after switching on the headset, if not, press reconnect on the phone. 2. If the phone has been powered off and headset is then disconnected, the headset will reconnect automatically when phone turns on again. Otherwise, turns on the headset again. 14 Using Your Headset FunctionButtonAudio (Speaker) Status Indicator Incoming Call--Ringtone (Musice will stop durung incoming call) Blue light flash 3 times in every 3 seconds Answer a Call (Standby mode / music playing mode) Pr ess MFB once to accept ‘Di Do’ tone once During the call, blue light flash in every 5 seconds Answer a Second Call 1.

RF Exposure Evaluation 1.1. Limits According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (Minutes) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- f/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- f/1500 6 1500-100,000 -- -- 1 30 f= Frequency in MHz Calculation Formula: P d = (P out *G)/(4*pi*r 2 ) Where P d = power density in mW/cm 2 P out = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 r = distance between observation point and center of the radiator in cm (The minimum distance is 20cm) P d is the limit of MPE, 1mW/cm². If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Report No.: 1403RSU01002 FCC ID: WD3UA28SE Page Number: 4 of 4 1.2. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. The temperature and related humidity: 18°C and 78% RH. 1.3. Test Result of RF Exposure Evaluation Product Bluetooth Headset Test Item RF Exposure Evaluation Antenna Gain: The maximum Gain measured in fully anechoic chamber is 0dBi for 2.4GHz in logarithm scale. Output Power into Antenna: Test Mode Frequency Band (MHz) Maximum output power to antenna (mW) Limit of Power Density S(mW/cm²) Bluetooth 2402~2480 0.242 1 Per FCC KDB 447498 D01v05r02, the SAR exclusion threshold for distances<50mm is defined by the following equation: Based on the maximum conducted power of Bluetooth and the antenna to use separation distance, Bluetooth SAR was not required; [(0.242mW/5)* √2.480] = 0.076 < 3.0. Note: When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. The End
