Instruction for use
1. Introduction
Congratulation! You have just bought a most sophisticated FM wireless stereo sound system.This system
uses the latest FM wireless technology, which gives you complete freedom of movement while enjoying
your own favorite music. No more inconvenience from cables or headphone wires! To ensure you get the
best performance of your FM stereo sound system, please read this document carefully.
2. Features
•Wireless transmission - the FM transmitter transmits the stereo audio signal from your audio or
video source to your FM speaker (receiver) without wires.
•Wide transmission range - the FM speaker (receiver) receives signals from up to 100 meter away
from the FM transmitter.
• High-frequency radio system - the FM speaker set uses a high radio frequency as the signal carrier,
ensuring a very clear, sharp reception.
• Mute function - reduces the noise level by 90% when the sound signal is too low or not available.This
feature makes it possible to have the noise reduced when e.g. tuning the receiver to the transmitter.
•Automatic power on/off - the FM transmitter automatically switched on and starts transmitting
when signals are sensed at the input (indicated by green LED).When there are no signals at the input,
the FM transmitter automatically switches off.
• No space limitation - the FM speaker (receiver) is able to receive signals from the transmitters, even
through barriers such as doors, walls and glasses.
• Multiple headphones / speakers with one transmitter - additional number of headphones and/
or wireless speakers can be used with a single transmitter.
•Trackball volume control - volume can be adjusted at the speaker.
• Built-in 8 Watt amplifier - produces high-power sound
• Battery or mains operated - speaker can be powered by batteries or mains.
• Bass reflex system - for powerful bass reproduction.

5. Installation
• SBC BC200 powered byAC/DC adapter.The current mentioned on the rating label for the speaker
is 9V/1000mA, but the SBC BC200 can be used with the supplied 9V/500 mA AC/DC adapter. Insert
the AC/DC adaptor plug into the DC input jack (7).Then check that the voltage mentioned on the
rating label of the AC/DC adapter is in line with the voltage of the wall outlet If it is correct then
plug the AC/DC adapter into a standard mains power outlet Or insert the batteries (6 x R6.AA)
into the battery compartment as shown in Figure I. Ensure that the polarity is correct
• Insert the DC connector of the AC/DC adaptor Into the 12V DC/200mA input connector located
in the rear of the FM transmitter.
• Connect the audio source (CD player,TV. HiFi) to the FM transmitter with the HiFi audio cables as
shown in fig I.
6. Operation
• Switch on the FM speaker
♦Apply an audio signal to the transmitter (using an audio source such as CD player.TV.or HiFi).The
FM transmitter will switch on automatically.
•Tune the tuning control on the speaker until signal (audio sound) is at its clearest.
•Adjust the volume of the audio source to the highest acceptable undistorted level.
• When you no longer require the speakers, turn off the power switch to save power.
• When the battery power runs low, the battery indication (5) becomes less bright and the sound
quality degrades; when this happens replace the batteries.
• Switch the "mono-stereo” switch to "mono" to listen to one speaker in mono only.
• Switch the "mono-stereo" switch to "stereo" to listen to two or more speakers in stereo.
• Switch the "L-R" switch, (located inside the battery compartment) to LEFT or RIGHT to determine
the speaker's signal reproduction side (L=Left. R=Right).This only works in stereo mode!
Note :There is more audible noise from the speaker in stereo mode compared to mono
operation; this is not due to speaker, but due to the FM stereo principle.

8. Precautions
• This speaker system works only on a 9V DC supply. If the system has not being used or will not be
used for some time, please remove the batteries to prevent leakage and corrosion.
• Do not leave the speakers near heat sources. Do not expose to direct sunlight, excessive dust,
moisture, rain or any kind of mechanical shock.
• Do not use alcohol, thinner or petroleum-based substances to clean the speakers.
• If fluid spills into the speakers, remove the batteries immediately and consult an authorized dealer.
• Keep the mini speakers away from TV or credit cards using magnetic coding to prevent any damage
caused by the speakers' magnets.
• Make sure to turn off your speaker to save energy when you have stopped listening.You will hear a
noise sound a few minutes after the transmission stopped to remind you to turn off the speaker.
