2. Connect the supplied AC/DC power adaptor to an electrical wall outlet.
3. Plug the AC/DC power adaptor in the DC jack located on the rear of the
transmitter.
4. When the AC adapter is plugged in, the red POWER LED illuminates. If the red
POWER LED does not illuminate, make sure the adapter is plugged in.

output jack of TV, Monitor, VCR, Radio recorder, CD/MP3/VCD/DVD players or
to headphone/earphone jack with the connector provided.
When the transmitter received an audio signal, the blue SIGNAL LED and the red
POWER LED will illuminate together. If the blue SIGNAL LED does not illuminate,
ensure the audio source is turned on.
SPEAKER RECEIVERS
1. Insert 6 pieces ‘C’ size ALKALINE battery into the battery compartment with
correct polarity at the bottom of each speaker (batteries not included in the
package) or connect the 9V power adaptor to the DC input jack on the bottom of
each speaker, then plug it to the wall AC outlet.

mounting. There are two holes at the back of each speaker for you to hang
them on the wall.
REMOTE CONTROL UNIT
1. Remove the battery cover at the rear of the remote control unit and insert 2
pieces “AAA” size batteries provided into the battery compartment with the
correct polarity.
2. Place back the cover and close the battery compartment.
P.4
OPERATION
1. Turn on the audio source (TV or audio component) to which the transmitter is
connected with. The blue signal LED on the transmitter will light up.
2. Select the channel 1 or 2 of the transmitter for best performance in your
location.
3. Turn on the ON/OFF button on the speakers (the ON/OFF button on the remote
control unit cannot be used as a primary device to switch on the speakers).
Press the “AUTO TUNE” 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. Tuning process can also be activated by pressing the
“AUTO TUNE” button on the remote control unit.
4. Volume can be adjusted up by pressing “+” button or
down by pressing the button “-“ to the desired listening
level, or you can press the “+” button or “-“ button” on
the remote control unit to adjust the volume level.

disruption. Should there is any disruption (signal cuts off or carries distortion), press
the speaker’s “AUTO TUNE” button to maximize the best reception.
If you hear interference from other components, switch on the channel control of
transmitter, and then move the speakers to other free location. You can re-adjust the
tuning control by moving it either channel 1 or 2 of the transmitter, then pressing
“AUTO TUNE” button for best reception.
When transmitting / receiving over long distances, the signal from the system will
become weaker.
