Accessories 8-7
Multi Media Card (MMC) / Secure Device (SD) Card
The MMC provides secondary non-volatile storage. The MMC is located under the keypad (see Figure
8-1).
SD cards are inter-operable with MMC cards and can also be used in MC9000
mobile computers.
Do not remove the keypad while the mobile computer is on and do not operate
the mobile computer with the keypad detached. Follow proper ESD precautions
to avoid damaging the MMC/SD. Proper ESD precautions include, but are not
limited to, working on an ESD mat and ensuring that the operator is properly
grounded.
To insert the MMC/SD:
1. Suspend the mobile computer.
2. Remove the two keypad screws and slide the keypad down and lift off (see Figure 8-1 on
page 8-5).
3. Lift the MMC/SD retaining door.
4. Position the MMC/SD, with the contacts down, into the MMC/SD holder. The MMC/SD
corner notch fits into the holder only one way. Snap the retaining door closed.
