P.2 COMPONENT IDENTIFICATION TRANSMITTER SPEAKER RECEIVERS REMOTE CONTROL Antenna Signal On Indicator (blue) Power On Indicator (red) VOLUME DOWN VOLUME UP POWER ON/OFF AUTO TUNE AUTO TUNE VOLUME UP VOLUME DOWN POWER ON./OFF P.3 INSTALLATION TRANSMITTER 1. Insert the antenna tube into the antenna wire. 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. 5. The rear of the transmitter has one audio cord that can be connected to audio 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. P.4 2. Press On/Off button and turn the speakers ON. The POWER LED will light up in Blue. Switch off the speakers by pressing the ON/OFF button on the speakers or on the remote control unit, and the LED will be off. 3. To suit the needs of different users, these speakers are designed for wall 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 (not included) into the battery compartment with the correct polarity. 2. Place back the cover and close the battery compartment. P.5 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. NOTE : a). Keep a distance of the speakers up to 7 meters apart from the transmitter, and then press “AUTO TUNE” button for the best reception. b) Whenever you find frequency jam, move your channel switch from one channel to the other channel (there are two channels for selection) on the transmitter, and then press the “AUTO-TUNE” button again. P.6 5. You should now be able to place the speakers freely from room to room without 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. 6. Switching Off a) For protection of the transmitter and power saving, the transmitter will cut off automatically if there is no/weak operation input signal from audio source for 4 minutes. In other words, if the signal comes back, the transmitter will work again automatically. b) Press the ON/OFF button to turn off the speakers and the LED light goes off, or simply press the ON/OFF button on the remote control unit. If you use the remote control unit to turn off the speakers, the speakers will be at stand-by mode for 5 minutes and the LED will be changed from blue to yellow. You can switch on the speakers again by using the remote control unit during the stand-by time. If there is no signal from the remote control unit in 5 minutes, the speakers will automatically power off. P.7 WARNING: THE POWER ADAPTORS ARE FOR INDOOR USE ONLY. IF IT IS SLIGHTLY RAINING, KEEP THE SPEA…
