1 The rmware for the CY920 MODULE is written to the INTERNAL ROM of the CY920 and the IC501 (EXTERNAL ROM) of the DIGITAL
circuit board.
"
CY920 Error
" appears in the display if the DIGITAL PCB or the CY920 is replaced, as this results in the version of the INTERNAL ROM
differing from that of the EXTERNAL ROM.
In this case, see "Update Procedure in the Event of a CY920 Error".
(This does not require special operations such as pushing multiple buttons at the same time. The rmware also cannot be updated via
DPMS.)
