CAUTION
1 Before replacing the base printedcircuit board, remove the
card PCBs and DIMM modules on the base printedcircuit
board, and mount them on a new base printedcircuit
board. As the memory module is removed, the SRAM
memory contents are erased. Therefore, before starting the
replacement, check that a backup copy of the latest SRAM
data is saved in a memory card or Handy File. Also, it is
recommended that the data in the SRAM be backed up into
the builtin FROM of the Power Mate. See Appendix E.
