Rear Check problem

SOURCE: Samsung SWA-4000 Wireless connection problem - Not connecting with main unit

I have had the same problem with the wireless unit and thought the same, it didn't work. The way to fix this is simple. You need to do the 0, 1, 3, 5 on the remote and turn on the home theatre system on the main switch on the front panel (as I was doing this on the remote, and it was failing). The blue light should then stay illuminated. If not just switch the main on/off button again, and it shoud work.

hi...im not sure how it happened...what i did was i pressed 0135, the main unit lit up and i pressed the id set or something like that on the back of the wireless reciever.....well the main unit should be back to red and once i pressed the id set i accidentaly pressed the power button so the main unit turned on...then i waited for the wireless reciver to boot up and worked.....

Turn on the HT with no DVD. Press the following buttons on the remote: ENTER 8, 4, 2, 6, 9 ENTER 
It will turn off. When turned again on it is a region free HT.

I was having poor audio from the back speakers and didn't even know it; intermittently I'd hear them jump in volume, so myself being a little adventurous, decided to push the ID set button on the back, totally losing my ilnk... after digging and playing, I figured it out:
1.) Turn off the Head (main) Unit 2.) Power on the wireless receiver, being sure it is away from routers, other BT devices, etc. 3.) Push the "ID Set" button on the back of the wireless device and hold it until the lights on its front panel flash. 4.) Point the system's remote control at the Head Unit and punch in 0135.  Its light should turn from red to blue. 5.) Perform step 3 again. 6.) Power on the head unit.
Should link up.
Might be some redundancy there, but it works :)
Also I found that after a few cycles It seemed to work better (perhaps cycled to a better channel?)
