Plug the iPhone/iPod to the socket for audio output and charging. Power/Signal Indicator (Green/Blue) 30 pin dock connecting socket P.4 When the power adapter connection is finished, the LED of transmitter will light up in Green. When the audio cable connection is finished or the iPhone/iPod is plugged to the 30 pins dock connecting socket, turn on the audio source and the LED will turn from Green to Blue. SPEAKERS 1. Charge the speakers by placing them on the transmitter station for 12 hours before initial use. Alternatively, the built-in rechargeable battery pack can be replaced by 8 x “AAA” size ALKALINE batteries. 2. Switch the Power button and turn the speakers ON. The Power/Standby LED will light up in Blue. 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 isconnected with. The LED will turn from Green to Blue. 3. Turn on the transmitter by switching the ON/OFF button on the rear of transmitter. P.5 4.Turn on the Power button on the speaker and adjust the volume by tuning the volume button for desired listening level. 5.You should now be able to place the speakers freely from room to room without disruption. 6.When the battery is low, the light on the speaker will blink and there is a “du du” sound notification to alert the user to charge the speaker. 7.If no music is detected from speakers, a paring process is required. Paring is not necessary if the system works properly. Paring 1.Press “Pair” button for 3 seconds on transmitter, the paring process will continue and LED will flash for about 15 seconds. 2.Press “Pair” button for 3 seconds on speaker when LED on transmitter is flashing. 3.Once the Pairing process is finished, LED on transmitter and speaker turn to solid blue. Music will stream out. 4.When Pairing is matched once, there is no need to do further at next applicatons. P.6 Charging the iPhone/iPod 1. Connect the power adapter between wall jack and transmitter. The LED will turn to Green. 2. Plug the AC power adapter in the DC jack located on the rear of the transmitter. 3. Plug the iPhone/iPod to the 30 pins dock connecting socket to charge the iPhone/iPod. SWITCHNG OFF 1.If there is no audio input signal to transmitter in 4 minutes, transmitter will P.7 go to standby mode and LED will change from Blue to Green. 2.Turn the switch on the rear of transmitter to OFF. 3.If the power adapter is unplugged, the LED on transmitter will turn off. 4.Speaker will turn to standby mode if there is no input signal to transmitter and LED will become Green. At standby mode, speaker will turn to On automatically after getting signal from transmitter. Charging the speakers 1. Make sure the switch in the battery compartments is at charging condition. 2. Turn your speakers to off. 3. Place your speakers to the right positions of the cradle on the transmitter. 4. The LEDs on speakers will light up in Red if the charging is under process. Charge Normal REMARK: For better rechargeable battery life performance, speakers should be turned off when charging. 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 switched ON. -Speaker’s battery capacity is too low, turn off the spearkers and recharge the speakers by placing them on transmitter station. -Ensure the TV or audio component is ON. -The connected audio / video equipment is not playing. Start playing C h a r g e N o r m a l P.8 the equipment. -The volume of speaker is too low, adjust the volume to an appropriate level. DISTORTED -Battery capacity is too low. Recharge the speakers. -Ensure the volume level of speakers is adjusted properly. -The speaker is 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 TECHNICAL SPECIFICATIONS Transmission Mode: UHF stereo Carrier Frequency: 2.4GHz Operation Voltage: Transmitter, DC 15V 2.0A Frequency Response:20Hz–20KHz Distortion:1.5% S/N Ratio: 80dB (typical) Channel Separation: 50dB (typical) Operation Distance: Up to 50 meters Output Power: 2 x 5W (Max) Canada Statement This device complies with RSS-210 of Industry and Science Canada.
