Inserting/changing the card
The MMC is designed so that it can also be removed and inserted when the power
is on. The IM 151-7 CPU must, however, be switched to the STOP mode (see the
warning on page 8-6). The chamfered edge of the MMC prevents the card being
inserted the wrong way round (reverse polarity protection).
There is an eject button on the memory card slot to enable you to remove the card
easily. To eject the card, press the eject button with a small screwdriver or a
ball-point pen.
