|Correct way to fix this is. |
Press and hold the DOWN/SELECT & UP/INPUT simultaniously for 2-3 seconds until it says POWER BUTTON LOCKED or POWER BUTTON UNLOCKED
To change between screen inputs, press and hold the INPUT-side of the "UP/INPUT" button for about 3 seconds until the menu comes up, then use the DOWN-side of the DOWN/SELECT-button to change. To select alternative, press input for 3 sec, then select teh UP-part of the UP/INPUT button to select the other.
Yeah..this is NOT intuitive... :(
