SP1490 900MHz Digital Hybrid Wireless Outdoor Speakers System User’s Manual Please read before using the equipment P.1 INTRODUCTION This 900 MHz wireless speaker system uses latest wireless technology that enables you to enjoy music and TV sound anywhere inside or outside your home. You can simply connect the system to any audio source such as Radio, TV, VCR, Hi-Fi and CD/MP3/VCD/DVD player. Without complicated wiring and installation with your Audio/Video equipments and rear channel amplifier, the system enables you to enjoy thrilling, lifelike sound in minutes. FEATURES 1. Weatherproof indoor and outdoor speakers. 2. Automatic Phases Lock Loop (PLL) scanning system on speaker receivers 3. Phase Lock Loop (PLL) transmission system on transmitter 4. 900 MHz RF technology panel-like speaker system. 5. RF technology lets you roam freely throughout your house. 6. Operating distance up to 150 feet. 7. No line of sight limitation. 8. Virtually interference free audio quality. 9. Auto ON/OFF control. 10. Auto tuning function. P.2 COMPONENT IDENTIFICATION TRANSMITTER SPEAKER RECEIVERS 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 adaptor is plugged in, the red POWER LED illuminates. If the red POWER LED does not illuminate, make sure the adaptor 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 green SIGNAL LED and the red POWER LED will illuminate together. If the green SIGNAL LED does not illuminate, ensure the audio source is turned on. SPEAKER RECEIVERS 1. Insert 6 pieces ‘AA’ size ALKALINE battery into the battery compartment with correct polarity at the bottom of the speakers (batteries not included in the package) or connect the 12V 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 POWER button and turn the speakers ON. The POWER LED will light up in blue. Switch off the speakers by pressing the POWER button on the speaker, and the LED will be off. OPERATION 1. Turn on the audio source (TV or audio component) to which the transmitter is connected with. The green LED on the transmitter will light up. 2. Select the channel 1 or 2 of the transmitter for best performance in your location. 3. Press the “POWER” button on the speaker to turn on the speaker. 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. 4. Volume can be adjusted up by pressing “+” button or down by pressing the button “-“ to the desired listening level. NOTE : a). Keep a distance of the speaker up to 7 meters apart from the transmitter, and then press “AUTO TUNE” button for the best reception. P.5 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. 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. P.6 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 “POWER” button to turn off the speaker and the LED light goes off. TROUBLE SHOOTING NO SOUND - Ensure the AC/DC adaptor 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/DC adaptors to the speakers. - Ensure the TV or audio component is ON. - The connected audio / video equipment is not playing. Start playing the equipment. - The volume of speaker is too low, adjust the volume to an appropriate level. DISTORTED - Press the “AUTO TUNE” button on the speakers until matching the frequency of the transmitter. - Change the position of the channel selector on the transmitter. You must then press the “AUTO TUNE” button on the speakers. - Battery capacity is too low. Replace with the new battery. - Ensure the volume level of speakers is adjusted properly. - The speaker is too far away from the transmitter, move it closer. - The input level of the audio signal is too low. Turn up the volume of the audio source equipment.
