Since you're dealing with IR only now, there won't be any conflicts with your neighbors.

Your Kameleon can be upgraded with codes over the phone, UEI/OFA have upgrade codes for addresses #2-1170,and #3-1171.

It would be easiest if you can switch your receiver to address #1, use the preset code SAT -0775. Some commands that are missing can added via Advanced codes.

Your OFA model only takes 5 digit advanced codes, so you would add two zeroes to the FRONT each code in that link.
