Our MX-980 and MRF-350 combination has served us well for years. But the MX-980 started to have screen problems, requiring taking out the battery and putting it back in. So I upgraded to an MX-990.
Converting the CCP file to the MX-990 was pretty easy, and the new MX-990 (with the original MRF-350) can operate all of our equipment--sometimes. The system is set up to use RF only, and for purposes of my troubleshooting, each emitter is turned up to full intensity using the dials on top of the MRF-350.
When I push buttons on the remote, I consistently see the IR emitters light up, so I know the MRF-350 is receiving something from the remote and relaying it to the equipment. But it seems like I often (maybe 75% of the time) have to press buttons multiple times.
It doesn't matter what equipment I'm operating. I press a button and watch the IR emitter light up, but nothing happens. Then I press the button again and watch the IR emitter light up again, and the equipment responds.
I've tried skipping RF altogether by using IR only. All equipment seemed to operate normally.
This is confusing because the MX-980 could operate this equipment flawlessly (when its screen was still operational). Also, when I use CCP to use IR only, all equipment responds normally. So my issue only occurs with the MX-990 in conjunction with the MRF-350.
Can someone please suggest some troubleshooting steps? Thank you.
