19.4.2.5 Operation of function number 8 (saving to the memory
card in a batch)
This function saves battery backed–up main board data in a memory card
at a time. The data saved using this function can be restored at a time by
performing the operation for function number A or by using the
SRAMDATABACKUP function of the boot function.
(1) In the memory card slot (MEMORY CARD CNM1B) of the control unit,
insert a formatted memory card having at least 512 KB of available
space.
(2) Check that number 8 blinks on the LED, and press the push switch.
(3) While data is being saved in the memory card, the LED indication turns
clockwise.
(4) If the data cannot fit in one memory card, number 3 blinks. Replace the
memory card with another one, and press the push switch.
(5) If the protect switch of the memory card is not released or if the battery
capacity of the memory card is insufficient, number 2 blinks on the LED.
Replace the memory card with another one, and press the push switch.
(6) When the data has been saved normally, number 0 is displayed on the
LED. If the data cannot be saved normally, number 1 is displayed on
the LED.
(7) If SRAM PARITY occurs during data save operation, number 1 blinks
on the LED. In this case, it is impossible to save the data at a time. Back
up individual data items one by one, then perform all–clear operation.
