I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/thread/3300?tstart=0
Come back if it that doesn't help either.

PS. Just some friendly advice for the future. When you post on a forum it makes sense to use a proper subject title and ask in the proper area so people will look at it. The only reason I opened yours this morning was that there were only 3 unread posts. If there had been lots od unread postsI would have ignored it (I am the resident expert on remotes). To get my attention it should have benn titled something like "Need Remote for Canal digital, HD PVR 5743-CD" and should have been posted in the 'TV Source setup' area, as it has nothing to do with Audio/Video problems. .
