ADDING A NEW RX The DAS-2420 is designed to work with various Rxs, it can be configured to work with more than 16 Rxs (within the transmission distance). How to add a new Rx Step1: Power the Transmitter unit, press the power switch. Step2: Power on the Receiver unit, slide the power switch. Step3: Press Pairing key on the transmitter for 3 Secs. Transmitter will be under pairing mode, the LED on Tx will be blinking. Step4: Press the pairing key on receiver for 3 Secs, Tx and Rx are under pairing mode. The LED on Rx will be blinking. Step5: When the pairing procedure is ok, LED on Tx and Rx will dimmed at the same time, Pairing is OK. It will take 10 sec to do the pairing. FAQ No audio output 1. Check the power of Tx and Rx. 2. Check the audio connection on Tx and Rx. 3. Check the LED light on Tx, if there is audio presented, the LED will be lighted, if it is blinking that is means that there is no audio presented in Tx. There is some noise 1. Check the Tx and Rx are in the range of specification 2. Check if there are obstacles in the transmission range, such as microwave oven.
