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.

I have bought Slingbox 500 and searched the FAQ and Forums but can't find a working code for the Foxtel iQ2 used here in Australia.
I am also very disappointed to see there is no actual contact email to send to Slingbox. Bigger disappointment with the fact that many people are complaining that it takes so long before Slingbox produces the required codes. Slingbox, you have a great product, but certainly have a long way to make your customer service mathces your product.
