Try restarting the whole equipment and see if devices pair together fine on startup.

Your connection between the AR transmitter and the ONKYO receiver sounds solid. I'd guess it's the wireless speakers that are the wrong point, or at least that's what I'd look at first. Doing a bit of research, I noticed a couple minor points. First, these seem prone to RF interference from other RF devices. Have to tried switching channels on them? Second, someone reported theirs would not work properly unless the speakers were turned on just before the transmitter, and turned off shortly after the transmitter. Apparently you have to hold the button on the front in for 5 seconds to turn the speakers on or off. I know that's rather basic, but it's been a few days and no one else has responded, so I figured we should start somewhere.

First, determine if the TV device is putting out sound by plugging in a headphone into the audio out of the TV. If audio is there then the
transmitter and wireless speakers system may be at fault.
You can also plug in a CD player playing a disc into the transmitter to see if that source then transmits the audio.

If you just using them for stereo, use the "main pre-out" on the receiver. if your using them for surround, they need to go the 5.1 pre-out rear. Hope this helps.

you can find all kinds of adapters for RCA or phone jack to anytype of connectors at best buy or circuit city, if not Radioshak probably have them. just ask for a cable adapter to the type of connector transformation you need for the speakers.

ask google or you tube or go to car toys they can help. good luck

Do not restart them with the button, that won't reset settings, unplug everything from power for 5 minutes and plug them back.

Wher can you return it? Does anyone have and address? My Dads unit has a blinking blue light and the folks at sharper image say to bad so sad only after 2 months out of warrenty. Is there any one out there that can help? I am done buying things from Sharper Image with their attitude! [email protected]
