how do i set up the rs 120 wireless headset?
the rs 120 can be connected via a 3.5mm plug to a dedicated headphone jack (which will often cut off sound from external speakers) or to the red & white rca audio out connectors (often found on the back of your tv, cable box, receiver, dvr, etc.) and when connected this way will allow operation of both headphones and external speakers .

To connect the headphones, you will need to plug the transmitter into a power source and the audio cables into an audio source. When you plug the transmitter/charging station into the power outlet and place the earphones on the base, the red light will turn on to indicate that it is charging. When you connect the audio cables to an audio source (via the red and white RCA audio output jacks or a dedicated headphone jack) that is powered on, a green light will appear on the transmitter. the goal when connecting the audio cables is to get a green light on the transmitter because it indicates that the transmitter has located an audio signal. once you have the green light on the transmitter, it’s simply a matter of tuning the headphones to the transmitter. note: green light indicates that there is a power supply and an audio source present and not just one power supply, and sometimes the two are confused.
On many audio sources, the audio output connections are located on the back of the audio device and this is where the transmitter cables should be plugged in. A headphone jack is usually designated by a headphone icon, and analog audio RCA connections will usually be red and amp; white. sometimes the colors of the wires match the colors of the audio connections and sometimes they don’t, so some experimentation may be required. remember that the goal is to get the transmitter’s green light to come on and stay on. once the transmitter is plugged into the TV and the green light on the transmitter comes on, getting sound shouldn’t be a problem as it’s simply a matter of using the tuning dial on the headphones to locate the signal the transmitter is sending .
If the green light does not turn on or turns on and after a few minutes turns off when the transmitter is connected to both a power source and an audio source, it means the audio signal is too low (or not at all). reach the transmitter at all). The transmitter needs a good strong signal to work or the internal electronics will shut down in 5 minutes if no volume is detected or very little volume is detected to conserve battery life. if this is the case, then the signal level must be increased before reaching the transmitter. this can be achieved by boosting the source on the variable level outputs (i.e. TV volume) or by boosting the signal from a fixed level output (by boosting the output level to the audio output jacks, which is done through the TV setup options). ). try increasing it in small increments to avoid overload causing distortion. also check that it is connected to outputs and not inputs.
If you still can’t get the green light on the transmitter or you can’t adjust the audio settings on the TV, you can also try connecting to a set-top box (cable box, dvr, hd receiver, etc) through your audio outputs or connect through a headphone jack.
Note: If an analog audio output is not available on your audio source and the only option to connect your headphones is a digital audio output, a digital to analog decoder will be required to connect to the digital output and switch the digital signal to an analog signal for use by headphones.
a good digital to analog decoder is the orei da 34 (http://www.amazon.com/orei-da34-digital-5-1-channel-headphone/dp/b008epw7o0/ref=sr_1_1?ie=utf8& ;qid=1412708965&sr=8-1&keywords=orei+da+34)
