For more details about connecting speakers, please see your speaker instruction book. B. Connecting the Receiver with AC Power To a wall outlet. Connect the AC power only after all speakers are connected to the Receiver. Cable Hole 1. Open cover of the cable storage compartment at the bottom of Receiver. 2. Unwrap the cable and extend it to the desired length. 3. Close the cover. Make sure the extended cable is not pinched and comes out from the cable hole as shown in the diagram. 4. Connect the AC power plug to a wall outlet. 4. 5. Basic Operations Establishing Communication between the Sender and Receiver Units To power on the System. a. Press the button on the rear panel of Sender. The LED indicator blinks to indicate that the Sender is plugged in and in Standby mode. Sender b. Press the button on the rear panel of Receiver. The LED indicator blinks to indicate that the Receiver is plugged in and in Standby mode. Receiver c. The Sender and Receiver were pre-paired at the factory. When an active link is established between them, the LED indicators will be solid on and will not flash. Note: In case the indicators continue to blink after 30 seconds, it means there is no active link between the Sender and Receiver. Try to connect the System manually using the CONNECT button. For more, please refer to "Troubleshooting" on page 8. To listen to the System. a. Make sure the System is powered on, and there is an active link between the Sender and Receiver. b. Turn on your amplifier. Play the audio or video source at your amplifier. Enjoy using the wireless audio system!
To power off the System. a. Press and hold the power button for 2 seconds. The LED indicator will blink quickly first and then go off to indicate that the Sender is powered off. b. Press and hold the power button for 2 seconds. The LED indicator will blink quickly first and then go off to indicate that the Receiver is powered off. Note: It is acceptable to leave both units powered on when not in use. Additional Operations Placing the Receiver Adjusting the Volume To cope with your different specific needs, the Receiver can provide you three ways of placement. After the System is set up, it is recommended that a 1 time adjustment of the Receiver volume is made. 1. Placing the Receiver horizontally on a level surface. 2. Placing the Receiver vertically with the supplied holder. The volume control on the Receiver unit is only used to adjust the balance of the volume between the front and rear speakers. After the volume of Receiver is set up, always adjust the volume using the volume control on your amplifier whenever needed. Note: The volume control on the rear panel of the Receiver is only used during the set-up process to establish the relative volume between the front and rear speakers. 3.

Check the AC adapter is connected to the Sender and power cord is connected to the AC supply for the Receiver.
Check all the cables are connected correctly. Check to see if the LEDs illuminate on the front of both the Sender and Receiver units. If the LEDs are lit solidly then the communication is working correctly and all speaker wires and the amplifier operation should be checked. If the LEDs are flashing then follow through the "no communication between Sender and Receiver"
section below.
Move your Sender and Receiver slowly to find the best reception position for your System.
Shorten the distance between your Sender and Receiver. The maximum distance is 100 feet.
Check if there are any obvious radio frequency interference sources near your System.
Check the power cords of the System are connected correctly.
Once the power buttons have been pressed to turn on both the Sender and Receiver units, the front panel LEDs should illuminate. If they are solidly on then a communication link has been successfully established between the units. If they are flashing on one, or both, units then press and hold the CONNECT button on either the Sender or Receiver for 2 seconds. (The Sender's CONNECT button is at its bottom and the Receiver's CONNECT button is on its rear panel.) This will put the unit into the "connection mode" for about 30 seconds. During this period the CONNECT button on the other unit must also be pressed for 2 seconds so that it will also enter the "connection mode". Then, the System proceeds with the connection process between the Sender and Receiver. During the "connection mode", the LED indicators blink at a faster rate. When an active link is established between the Sender and Receiver, the LED indicators will be solid on and will not flash. Note: Try pressing the CONNECT buttons again if the LED indicators keep blinking after 30 seconds. 8. 9.
