Please remove tips from Optical cable before use. (best sound quality) (good sound quality) Transmitter (back) 2 line-in or AUX (better sound quality) Plug one end of an included charging cable into the DC IN 5V jack on the back of the transmitter. If your TV has a USB power outlet, plug the other end of the charging cable into this outlet. Otherwise, plug it into an AC outlet using the included USB power adapter. 3 2. IF YOU ARE STILL NOT RECEIVING AUDIO – You will need to adjust your audio settings of your TV (refer to your TV’s instruction manual to adjust audio settings. You are not receiving audio because your TV requires a setting change to output digital audio to Optical Out. Using your TV remote control , utilize your remote to go to settings usually using a MENU button and go to Audio Settings. There should be a setting for PCM or Digital Audio. If you can choose PCM choose this. Now check your headset – you should now be hearing audio. If you are still not able to receive audio please contact us at [email protected] and we will set up an appointment to walk you thru your set up. 3. TIP: If you are not receiving audio through your speaker and the indicator light is not solid blue, your system is not paired. To pair, press the hold button on the transmitter for at least 2 seconds and the indicator lights start flashing. Then you will press the tone button on the speaker until you hear a BEEP and let go. Then the indicator light on the speaker should start blinking. Once paired, both units will turn solid blue.

FCC ID: ZY9-HSSPKR Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR 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 When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
