7-3. Back Up and Restore
If you want to store the user's data before repair, you should back up user's data at first without
performing any other operations.
Otherwise, any data except user's data will be written in NAND type Flash ROM in the main PC
Board. Once these data are written in this ROM, these data can not be deleted even if the power is
not supplied to the unit. It is strongly recommended to restore the user's data after restoring the
factory defaults on the safety side.
There are two ways to back up/ restore the data.
1. Back Up/ Restore using CF card
Memory capacity of CF card should be more than 12 Bytes.
It is recommended to use CF card of which memory capacity is 32 Bytes on the safety side.
2. Back Up/ Restore using PC via PC Connect software
Caution on interchangeability between Main PC Board Assemblies
There are two kinds of Main PC Board Assemblies in BE-300 now.
The installed OS is different each other.
Therefore, the data made under the new OS can not be restored to the former main PC Board in
which the former OS is installed.
However, the data made under the former OS can be restored to the new main PC Boardd in which
the new OS is installed.
You can confirm this difference by the built No. and Unit ID No.
The built No. can be identified by the following operation.
1. Turn on the unit.
2. Display Top Menu pressing Top Menu button.
3. Tap Edit which exists in up/ Ieft side part in this display, and then Version.
4. Doing so, the following display will appear.
For example,
CASSIOPEIA
System Version 1.00.00(US)
(Built 002202-054)
00220-054 in this display indicates the former Built No.
If 002203-054 is displayed, the new main PC Board Assembly is assembled in the unit.
002202 and 002203 in Built No indicate Kernel part in OS.
054 indicates NAND DISK in NAND type Flash ROM, and is similar to Hard Disk on PC.
On the other hand, Unit ID No. is attached on the back of the unit.
Refer to the below table concerning the relationship between Built No. and Unit ID No.
