The rear of the transmitter has one audio cord that can be connected to audio output jack of TV, Monitor, VC R, Radio recorder, CD / MP3 / VCD / DVD players or to headphone / earphone jack with the connector provided. Plug the adaptor in the AC source and connect the audio plug to the audio source. As soon as the transmitter is receiving the audio signal, it will automatically switch on and the Signal LED (Green) will illuminate. P. 5 SPEAKER RECEIVERS 1. Insert 6 pieces ‘AA’ size ALKALINE battery into the battery compartment with correct polarity at the rear of the speakers or connect the 12V power adaptor to the DC input jack on the rear of each speaker, then plug it to the wall AC outlet. 2. Switch on the speakers by turning up the VOLUME ON / OFF knob towards ON direction. The POWER / STEREO LED will light up. Switch off the speakers by turning down the VOLUME ON/OFF knob towards OFF direction until a “click” sound is heard. OPERATION 1. Turn on the audio source (TV or audio component) to which the transmitter is connected with. The LED on transmitter will light up. 2. Select the channel 1 or 2 of the transmitter for best performance in your location. 3. Select the L/Mono/R selector on th e speaker receivers, one to L and the other to R for the best stereo reception. Ã In case the audio device only provides Mono audio signal, select the MONO/ST selector to MONO for the best mono reception. 4. Turn on the ON/OFF VOLUME knob on the speaker and adjust the volume to the desired listening level. P. 6 5. Push the “SCAN” auto-tuning button to get the best tuning reception in the speakers. When the button is pressed, frequency tuning starts automatically and it stops when a signal is detected. The POWER / STEREO LED will change from red to green. A). Keep a distance of the speaker up to 7 meters apart from transmitter, and then press “SCAN” auto-tuning button for best tuning reception. B) Whenever you find frequency jam, move your channel switch from one channel to the other channel (there are two channels for selection) on the transmitter, and t hen press the “SCAN” auto-tuning button again.
