That code may not work, as I mentioned previously.
That is the only code for your device. If it does not work, that is a limitation of your remote, not an issue with the code or receiver. It doesn't matter what code you use, that GE remote is not capable of controlling this receiver.
You will need a more robust remote, such as the logitech I recommended previously.
If you'd prefer a replacement OEM remote, I can help you find one of those.
Best regards, ***** ***** for the news,
I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.
Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately.
