18. MEMORY CARDS AND BATTERIES
(3) Memory card remove/insert prohibit flag (special relays SM605, SM625)
Instead of operating the memory card in/out switch, turning ON/OFF special relays
SM605 (memory card A) and SM625 (memory card B) can be also used as the card
remove/insert prohibit flag. Once removal/insertion is prohibited with the remove/
install prohibit flag, it is still disabled even if the memory card in/out switch is set to
"ON".
The relationship between the memory card in/out switch and the memory card
remove/insert prohibit flag is shown in the table below.
