COMPONENT IDENTIFICATION 1. TRANSMITTER 2. SPEAKER Power “ON” indicator DC Jack 3. REMOTE CONTROL UNIT D. INSTALLATION 1. TRANSMITTER A. Connect the supplied AC power adapter to an electrical wall outlet. B. Plug the AC power adapter in the DC jack located on the rear of the transmitter. C. Or you can insert 4 X “AA” size ALKALINE batteries into the battery compartment at the bottom of the transmitter with correct polarity. D. The rear of the transmitter has one audio cord that can be connected to audio output jack of TV, i-pod, DVD, and CD/MP3 players or to headphone/earphone jack with the connector provided. E. USB jack at side panel for audio input as well as recharging of iPhone & iPod. When the power adapter connection is finished, the LED of transmitter will light up in Green. When the audio cable connection is finished and turn on the audio source, the LED will turn from Green to Blue. 2. SPEAKER A. Insert 8 ‘C’ size ALKALINE batteries into the battery compartment with correct polarity at the bottom of the speakers or connect the 12V power adapter to the DC input jack on the bottom of each speaker, then plug it to the wall AC outlet. Battery Compartment B. Press Power button and turn the speakers ON. The Power/Standby LED will light up in Blue. 3. REMOTE CONTROL A. Remove the battery cover at the rear of the remote control unit and insert 2 pcs “AAA” size batteries (not included) into the battery compartment with the correct polarity. B. Place back the cover and close the battery compartment. E. OPERATION 1. Connect the power adapter between wall jack and transmitter. The LED will turn to Green. 2. Turn on the audio source (TV or audio component) to which the transmitter is connected with. The LED will turn from Green to Blue. 3. Select the channel 1, 2 or 3 of the transmitter for best performance in your location. 4. Turn on the Power button on the speaker and adjust the volume by pressing “+” and “-“ for desired listening level. Volume can also be adjusted by pressing “+” and “-” button located on the remote control unit. 5. Push 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. 6. Select the L/M/R selector on the speaker receivers, one to L and the other to R for the best stereo reception. In case the audio device only provides Mono audio signal, switch to MONO for the best mono reception. 7. You should now be able to place the speakers freely inside or out within 150 feet from transmitter. DC Jack SWITCHING OFF 1. If there is no audio input signal to transmitter in 4 minutes, transmitter will go to standby mode and LED will change from Blue to Green. 2. If the power adapter is unplugged, the LED on transmitter will turn off. 3. Speaker will turn to standby mode if there is no input signal to transmitter and LED will become Green. Speaker will automatically shut off when standby mode continues for 5 minutes. 4. Speaker will also turn to standby model if you press the POWER button on the remote control to Green LED. Speaker will automatically shut off after 5 minutes. 5. At standby mode, speaker will turn to On automatically after getting signal from transmitter. OTHER CONTROL 1. Select volume up and down on Speakers or Remote Control Unit. 2. Select Bass Boost On/OFF by pressing the “BASS BOOST” button on Speakers or Remote Control Unit. A Blue LED underneath the Bass Boost button will on. 3. If you hear interference from other components, re-adjust the tuning control by moving channel knob to 1, 2 or 3 of the transmitter, then pressing “AUTO TUNE” button on speaker or remote unit for best reception. F. TROUBLE SHOOTING NO SOUND - Ensure the AC adapter is fully inserted into the AC outlet and the power connection input on the transmitter. - Ensure the speaker is switch ON. - Speaker’s battery capacity is too low, replace with new batteries or connect the AC adapters to the speakers. - Ensure the TV or audio component is ON. - The connected audio / video equipment is not playing.

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. 3.2Field Strength Calculation The field strength at 3 m was established by adding the meter reading of the spectrum analyzer to the factors associated with antenna correction factor, cable loss, preamplifiers and filter attenuation. The equation is expressed as follow: FS = R + System Factor System Factor = AF + CF + FA – PA Where FS = Net Field Strength in dBuV/m at 3 meters. R = Reading of Spectrum Analyzer / Test Receiver in dBuV. AF = Antenna Factor in dB. CF = Cable Attenuation Factor in dB. FA = Filter Attenuation Factor in dB. PA = Preamplifier Factor in dB. FA and PA are only be used for the measuring frequency above 1 GHz. 3.3Conducted Emissions The EUT was placed on a non-metallic table 0.8m above the horizontal metal reference place and 0.4m from a vertical ground plane which is connected to the horizontal metal ground plane. Meanwhile, the AC main of EUT was connected to the distance of 0.8m line impedance stabilization network (LISN) during measurement. Initial measurements were performed in quasi-peak a…
