The transmitter connects to any standard audio line output with a stereo RCA audio cable or to any standard amplified speaker output via the supplied speaker cable. The transmitter can also be connected to other audio outputs, such as headphone outputs, by using an appropriate adapter. The transmitter can be adjusted to the audio level provided by the audio source via a transmitter volume control. 

Check the power outlet and the AC adapter; if possible, check for correct voltage of the AC adapter.

• Check the audio connection to the transmitter and ensure that there is audio present.
• Disconnect and then reconnect DC power.

• Check the power outlet and the AC adapter; if possible, check for correct voltage of the AC adapter.
• Adjust the transmitter volume control.
• Adjust the receiver volume control.
• In some cases, there may be strong interference preventing proper reception of the audio signal which can be caused by 5.8 GHz cordless telephones or 5.8 GHz wireless networks. Either eliminate the interference, locate the base unit of the cordless phone in another room, set the wireless network to use the 5.1 GHz frequency band rather than 5.8 GHz, relocate the transmitter, relocate or reorient the receiver.

• Adjust the transmitter volume control until clipping stops.
• Adjust the receiver volume control until clipping stops.
• In some cases, there may be strong interference preventing proper reception of the audio signal which can be caused by 5.8 GHz cordless telephones or 5.8 GHz wireless networks. Either eliminate the interference, locate the base unit of the cordless phone in another room, set the wireless network to use the 5.1 GHz frequency band rather than 5.8 GHz, relocate the transmitter, relocate or reorient the receiver.

• Adjust the transmitter volume control to achieve the desired audio level.
• Adjust the receiver volume control to achieve the desired audio level.
• Increase the output level of the audio source (connect transmitter to an adjustable output by using an adapter if necessary).

• In some cases, there may be strong interference preventing proper reception of the audio signal which can be caused by 5.8 GHz cordless telephones or 5.8 GHz wireless networks. Either eliminate the interference, locate the base unit of the cordless phone in another room, set the wireless network to use the 5.1 GHz frequency band rather than 5.8 GHz, relocate the transmitter, relocate or reorient the receiver.
• Adjust the transmitter volume control.

An unlimited number of receivers can be used that operate from the same transmitter. For example, you can operate two separate receivers to connect two speakers which are located apart from each other. Each speaker connects to one of the two audio outputs of the receiver. The other audio output of each receiver is not used in this case.
