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.
Thanks for reaching out to us here! The best place to request a new remote be added to our system is right in our Enhancement Requests and Product Feedback, right here in our forum. We do have a team adding remotes to our database and you can always check on what new remotes have been added in our What's New section. I will provide links below where you can find both of these sections.
Hope this helps!
