Q Change of the Suffix Code 

Serial No.Label tells you the suffix code as follows.

                                                               KX-MB283RU/KX-MB783RU

The SOC-IC mounted on the Main Board has been changed.
Therefore, the parts numbers of SOC-IC, Flash ROM and Main Boardare also changed.
After replacing any parts of those, make sure to pass the included leaflet and new CD-ROM to
the customer and ask them to install the MFS application software contained on the CD-ROM on
their personal computer. It does not work properly without being set up with the new software.
