New optical reader element (component designator 12PE1) for the following Bang & Olufsen models:
Master Control Panel 5500 (MCP5500)
Master Control Panel 6500 (MCP6500)
(Table remote controls for Beomaster 5500, Beomaster 6500 and Beomaster 7000).
This is an original Siemens SFH 900-2 component.
A bad opto reader causes the volume and tone control setting wheel to fail. Typical symptom of a failed opto is that the MCP lights up when the wheel is rotated, but settings can not be changed because the wheels rotation is not detected.
Note: If the MCP fails to light up when the wheel is rotated, the problem is often dirty switch contacts at the wheel (or bad batteries).
This is a direct replacement for the original Bang & Olufsen part.
