To listen to RCA input audio, disconnect from Bluetooth before using a RCA input device. • One device can only connects or control one Bluetooth speaker at a time. If device A connects and controls Bluetooth, device B cannot search or control the Bluetooth speaker. Device A MUST no longer be connected, then device B can connect and control. • If paring fails the first time, restart all the equipment and then follow the above instructions. • If you are unable to reconnect a previously connected device, remove the "BT Speaker"from the list of paired devices, and then follow the above above instructions again. • The Bluetooth connection will be lost if the distance between the speaker and the Bluetooth device exceeds 1 Om(32.8ft.). CARE AND MAINTENANCE • Turn off the power to the speaker when unused for long periods of time. • Ensure all equipment is turn off prior to cleaning.Surfaces and cabinet need noly occasional dusting/cleaning. Never use chemicals or solvents as they may damage the surface. Always clean using a dry cloth • Never touch the speaker drivers.

FCC ID:2BK8E-DOS-A52BT RF Exposure Evaluation Limits 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 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , Pout = 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 Pd id the limit of MPE, 1 mW/cm 2 . 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. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually.
