How to back up the operating system:
Table 10-1 Back-up of operating system on MMC
6WHS $FWLRQUHTXLUHG &385HVSRQVH
1. Insert new micro memory card into
the CPU
The CPU requests memory reset
2. Turn the mode selector switch to
MRES position and hold it there.
-
3. POWER OFF / POWER ON. Hold
the mode selector switch in MRES
position until ...
... the STOP, RUN and FRCE LEDs start
flashing.
4. Mode selector switch to STOP
position.
-
5. Mode selector switch briefly to
MRES position, then let it return to
STOP.
• CPU starts backing up operating
system on the MMC.
• All LEDs are lit during the back-up.
• After completion of the backup, the
STOP LED flashes. The CPU
prompts you for a memory reset.
6. Remove Micro Memory Card. -
