Hello- I have purchased a IR/UHF Pro Dish Network remote on eBay for my 508 receiver. I have tried all the instructions I could find (both from the manual and online) to get the remote set to recognize the receiver; no luck. I am now wondering if the eBay seller was incorrect and this remote will not work with a 508. The remote has what I think is a model number, 118579, on the back. It has the number "2" on the front of the remote, at the bottom. Any thoughts or tips would be very much appreciated. Thanks in advance!
