outlet and connect the adaptors power output plug to the  
back of the transmitter marked DC9V.  
2. Connect the audio connection cable to the AUDIO IN  
socket with the other end of the cord connected to your

can use the provided 3.5 - 6.3 mm plug adaptor or 2-RCA  
phono-plug adaptor to suit the connection of your audio  
source.

TROUBLE SHOOTING  
1. Cannot connect transmitter to TV because TV has no  
headphone jack or audio output jack.  
If your TV has no audio output jacks, then it is probably  
not a stereo TV. In this case, connect the transmitter to the  
VCR (if you have a VCR connected to your TV).  
2. Poor sound quality (Distortion).  
Distance between speaker and transmitter may be out  
of optimum range or transmission may be affected by  
interference. Select another channel on the transmitter &  
press the auto tune button on the speaker.  
Battery power is insufficient. Replace the batteries.  
3. No sound or no signal at the speaker.  
Transmitter is not on.  
Transmitter has no power (power adaptor not plugged  
into AC outlet and/or not connected to the transmitter) or  
the audio source has stopped sending audio signal to the  
transmitter.  
Audio source is not on or transmitters audio cord is not  
connected to an audio source, or audio source volume (or  
amplification) is too low to generate a signal.  
Speaker is not turned on or its volume is set too low.
