Secure Device Card
The Secure Device (SD) card provides secondary non-volatile storage (the flash memory is slower than RAM). The SD card holder is
located under the battery.
Follow proper Electro-Static Discharge (ESD) precautions to avoid damaging the SD card. Proper ESD
precautions include, but are not limited to, working on an ESD mat and ensuring that the operator is properly
grounded.
Do not use the SD card slot for any other accessories.
Select SD cards with environmental and/or the write cycle performance specifications that meet or exceed
the application requirements.
To insert the SD card:
1. Remove the battery (see Main Battery Removal on page 1-16 ).
2. Lift the SD card retaining door.
3. Position the SD card, with the contacts down, into the SD card slot. The SD card corner notch fits into the slot only one way.
4. Snap the retaining door closed.
