Power on the unit while pressing both the left and right CURSOR buttons to check the firmware version. You'll see a screen like this:
After a few seconds it will change to this:
It's asking you if you want to perform the button test.
IF YOU DO THE BUTTON TEST A FACTORY RESET WILL BE PERFORMED BEFORE DOING THE TEST.
I'm not trying to make a scene or anything, I just want you to know that all your patches and settings will be wiped out if you do the test. Pushing the EDIT, PLAY/PERFORM, PARAMETER left or right, or DEC buttons will get you out of doing the test. Pushing the INC button will do a factory reset and begin the test.
"Switch 1" is the STORE button. Push it.
"Switch 2" is the UTILITY button.
Ok, I've given you enough clues. I'm not here to take the test for you!
After you have successfully passed the test, the unit will reboot and do the greeting animation and everything.
