Transmitter Set Up/Operation
1. Plug the transmitter AC/DC power adaptor into an AC outlet and connect the
adaptor’s power output plug to the back of the transmitter marked DC 9V.
2. Connect the audio connection cable to the AUDIO IN socket with the other end of
the cord connected to your audio source (e.g. stereo system, TV system etc.).
You 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.
3. The transmitter will automatically power up when there is an audio signal received
from your audio source. The red LED light will illuminate to indicate the transmitter
is powered ON.
4. Set the “CHANNEL” button to select the transmission channel as displayed by the
channel indicator.
5. Ensure the antenna is extended completely vertical to provide maximum
coverage.
Speaker Set Up/Operation
1. Use the provided 12V AC/DC adaptor to power each speaker. Plug the speaker
AC/DC power adaptor to an AC outlet and connect the adaptor’s power outlet
plug to the back of the speaker marked DC 12V.
(Remark: Each speaker can be powered by 8 AA batteries)
2. Since it has equipped with Auto tune function, you just need to change the
channel switch on the transmitter for optimum signal.

TROUBLE 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 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 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.
