X15 Remote and Hisense Amazon FireTV Control Codes

I recently purchased a 24" Hisense Amazon FireTV from Costco, Model 32A45NFC and am attempting to pair the X15 DVR remote to it. I have found two control codes under "Hisense" that control the volume and mute. I have also found two control codes under "Amazon FireTV" that will do the same.

What I have NOT found, is a control code that will do those two things AND also activate the "TV Input" button on the X15 remote, thereby allowing me to switch TV inputs.

Does anyone know one or more control codes that will also activate the "TV Input" button?
