USER’S MANUAL 2 3. 2.4G Wireless Rock Speaker Specifications Active Speakers & Receiver Power Source USER’S MANUAL 3 4. Application 2.4G wireless Telecontrol Speaker System can transmit the wide frequency, Hi-Fi music, sound signal. Transmitting frequency accord international criterion, can be used widely in the place where needed wireless transmitting, can be connect to the MP3 CDDVDIPOD. 5. Direction for use Power supply mode FYS012WL has two modes: DC, AC DC: There is a battery box of AA 1.5V on the bottom of FYS012WL. There is a waterproof switch for cutting off the DC Power. When the red direction light is bright, and the green one is off, the speaker works on standby stating, and you can on/off by the controller. This set is still consume power in standby stating, so please cut off the switch when you don’t use the machine. If you will not use the set for a long time please take out the battery to avoid battery leakage corrosion the machine. AC: Power supply is 120V. Cutting off the AC, please connect the power wire to the jack on the bottom of FYS012WL. The direction light is bright, and it’s red. Before play, make sure you have already offer one kind of power supply. After connect the power supply correctly, the direction light is bright, means the machine work correctly. Then connect the power supply to the Transmitter, and input the right audio signal to the Transmitter. Finally, you can tune on the speaker through the controller, enjoy your music. USER’S MANUAL 4 6. Use of Transmitter The power supply of Transmitter is DC 7.5V, we offer a normal power adapter. After connect the power to the Transmitter, turn on the power switch, the red direction light bright. There is a Power Switch and channel button on the front of the transmitter a Power Switch and channel button a power input interface and audio input interface. USER’S MANUAL 5 7. Use of Controller Three button on the controller: B is on/off of sound signal button A and C is for control the volume. C is for volume up. A is for volume down. (Note: Maybe at the beginning of working, the volume may be weak, you have to use C to make the volume loud.When speaker on battary supply mode,the lack of battery’electric quantity and Controller’battery electric quantity lack will make the control distance shorter.) Choose the channel FY S012WL offer 8 switchover channels: 012345678 Switchover Channels: After electricity the transmitter, it initialization for Channel 1, each press the button on the CH Channel will launch a channel up, the speaker will automatic progressive scan stereo receiver. Failure Indication If this machine can’t work normally, please check-up the following, whether it is possible to use the simple proposed measures to solve the problems. If the machine surely has problems please contact with the dealer. Problem Reason Correct Connecting according to the Direction for use, turn on the controller, no sound Transmitter has not Initialized Audio source do not connect to transmitter. Press the power button of Transmitter, restart the Transmitter. Check the connect between the audio source and transmitter. The sound change and controller distance become near. Speaker battery or controller battery is almost out. Change the battery
