Always: Make sure battery compartments are secure. • Use batteries of the correct size and type. • Fit batteries correctly observing the plus (+) and minus (-) marks on the battery and compartment. • Replace a whole set of batteries at each time. • Remove dead batteries from equipment. • Remove batteries from appliance that will not be used again for a long time. • Please remember that small button cells and AAA batteries should be kept away from young children as they could be easily swallowed. Seek medical advice if you believe a cell has been swallowed. Never: • Mix different types of batteries. • Mix old and new batteries. • Dispose of batteries in a fire. • Do not attempt to recharge ordinary batteries. PLEASE RETAIN THIS INFORMATION FOR FUTURE REFERENCE. FUNCTIONS BATTERY INSTALLATION BATTERY SAFETY INFORMATION BATTERY SAFETY INFORMATION CONNECTING THE WIRELESS TRANSMITTER The Wireless Speaker System is supplied with a universal audio cable. This cable can be connected to the audio source outputs with the 3.5mm plug or the red/white RCA plugs. NOTE: THE HEADPHONES SET WILL NOT FUNC- TION PROPERLY WITH THE 3.5MM AND RED/WHITE RCA PLUGS AT THE SAME TIME. 1. Connect the single 3.5mm plug to the Line-in jack at the back of the transmitter (shown in the diagram). Troubleshooting If your headphones are experiencing a noticeable degradation in wireless audio quality, first check the possible causes below. If you are unable to remedy the problem by following these hints, check user manual for further details. Under no circumstances should you try to repair the set yourself. Problem Interference from other radio sources or fluorescent lamps Volume level too low No Sound Poor Sound Quality Distortion Solution • Move transmitter or headphone elsewhere. • Adjust the volume level of the headphones, or adjust the output level of the audio source, which is connected to the transmitter. • Ensure the Transmitter switch is in the ON position by raising the antenna to an up-right position. • Ensure the headphones power switch is in the ON position. • Headphone or Transmitter batteries may be too low. Change batteries. • Ensure the TV or audio component is ON. • Adjust the volume control on the headphone to turn up the volume. • The connected audio/video equipment is not playing (CD, Tape, etc...). Check the audio source. • The volume of audio source is turned down, adjust volume to an appropriate level. • Ensure the Antenna on the Transmitter is extended to the fullest. • Headphones or Transmitter batteries may be too low. Change batteries. • Out of range. Move closer to the Transmitter. • Headphones batteries may be too low. Change the batteries and replace with new ones. • The headphones are too far from transmitter, move closer. • The input level of the audio signal is too low. Turn up the volume of the audio source equipment. FOR HEADPHONES 1. Open the battery compart- ment cover by sliding the latch forward and then pulling up. Insert two (2) AAA 1.5V Alkaline batteries into the battery compartment with the (+) and (-) poles correctly aligned. 2. Secure the battery cover before use. This product is subject to continuous improvement; we reserve the right to modify product design and/or specifications without notice and without incurring any obligations. FOR TRANSMITTER 1. Remove screw to access the battery compartment. Insert four (4) AAA 1.5V Alkaline batteries with the (+) and (-) poles correctly aligned. 2. Before use, secure the compart- ment cover by tightening the screw. CHANGING THE BATTERIES If the power indicator light is dim you may need to replace the battery. Please follow instructions above for replacing (installing) batteries. Thank you, we hope you enjoy your selection.

OPERATION DESCRIPTION FOR 49MHz FM WIRELESS HEADPHONE Transmitter; The transmitter is switched and connected to the input audio signal. The AF signal flow the voltage control capacitor diode to modulate with an oscillation frequency which controlled by a phase lock loop controller IC SA8803. This circuit is a transmitter for FM and amplifier by a transistor 9018G to transmit the RF signal by a rob antenna. Receiver; It received the signal from the wire antenna at the head belt. The signal flow a Transistor RF signal amplifier and go into a mixer which combine with a crystal control local oscillator. It produce an IF signal and it go into a FM receiver IC TA2003 to demodulate the AF signal. The TAD2822M amplified the AF signal and flow the speaker to provide the audio sound to the user. Antenna and ground circuitry This unit set makes use of a external flexible rob antenna for the transmitter and external fixed wire antenna for the receiver. Those antenna are inductively coupled. The unit set relies on the ground tract of the printed circuit board. No external ground provided. Energy is supplied by a 6 Volt batteries or AC/DC adaptor for the transmitter and 3 Volt batteries for the receiver.
