So I've run into a unique problem after purchasing an older Sr5200 to play music at home that came without a remote.
In order to enter the setup menu the procedure is to 1. Click the AMP button on the remote, then press the OSD/Menu button afterward, which takes you to the speaker config menu on the Avr front panel.
So I thought, easy just need to use an android ir remote app and we off to the races. We were not. I tried many apps but all suffered the same issue. The volume and power would work and many other functions but the menu button would not.
After some research I found the hex codes for the Sr5200, it actually uses a different menu command or way to access it compared to just about any of their other products.
I found the hex for the menu/osd button, loaded that into Irplus but the reciever would only turn the osd on or off, never go into the setup menu. I noticed that the hex code for osd on and osd/Menu are exactly the same. Which leads me to believe that when the Amp button on the actual remote is pressed it changes the way it sends the code from the osd/menu button in some way to activate its second function.
So here are my sources if you want to confirm what I'm saying. Anyone know a way around this? How did the universal remotes of the day navigate this challenge? Help appreciated, but do have a replacement remote on its way but will probably be a month until it arrives.
The marantz ir hex DB you can see all the commands supported by the SR5200 in colulm bb, and the command im reffering to is in row 28.
And then here is the manual, on page 11 the outline the procedure and on 7 describe the button.
Loving the sound of the reciever though, but I know it's got more power to give once a adjust some settings.
