My module HT-TX715 blinks rear chk and the rear speakers doesnt work.

SOURCE: just connected the SWA-4000 wireless

Actually the SWA-4000 IS compatible with the htz-310t. I'm using the htz-310 system with an SWA-4000 and it works perfectly fine. under the list of compatible systems with the SWA-4000 you'll see the htz-310. so i don't know where the other answerer is getting his facts.

once you press the nubmers on the remote, 0, 1, 3 5 or whatever the numbers are. turn the system on with the on button on the system not of the remote.

if the blue led is on on the swa-4000 then it's communication, there's a link.

if you do a sound test it will not send the static to the rear speakers, at least it doesn't for me. however there IS sound ouf of those speakers. so i know they work.
