SOFTWARE : SYSTEM
Also be sure to replace the NFC Module at the
same time.
b
1 The firmware for the CY920 MODULE is written to the INTERNAL ROM of the CY920 and the IC812 (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 firmware also cannot be updated via
DPMS.)
Procedure after Replacement
A : The software has been written. The software is not written at the time of replacement.
B : The software has been written. The software may need to be rewritten by version updates. Check the version.
C : The software has not been written. The software needs to be written after replacement.
See "
Firmware Update Procedure" for information on writing the software.
D : The software has been written. Be sure to rewrite with the latest software for your service region.
See "
Firmware Update Procedure" for information on writing the software.
