PROBLEM SHOOTING
Problem: Cannot connect transmitter to TV because TV has no headphone jack or audio output jack.
Solution: 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).
Problem: Poor sound quality (Distortion).
Solution: 1. 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.
2. Battery power is insufficient. Replace the batteries.
Problem: No sound or no signal at the speaker. Transmitter is not on.
Solution: Transmitter has no power (power adapter 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 transmitter’s 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.
