3. About Expansion cards
Several current models of Palm
 handhelds support SD (secure digital) Memory
Expansion Cards. These expansion cards offer the advantage of being able to retain a
software program (such as CPLINK) when batteries get low or fail completely.
If the user has a Palm
 with the SD expansion card and loses battery power, it is then a
simple matter to replace the AAA batteries (m125), or recharge the unit (m500). The
CPLINK program can then be copied back into RAM (Random Access Memory) from
the SD card.
4. Copying a program from the SD expansion card to RAM
It is a simple procedure to copy a program such as CPLINK to or from RAM in the Palm
devices that support SD expansion cards.
1. With the Palm
 turned on tap the menu bar icon at the
bottom of the digitizer screen.
2. Select "Copy" from the pull down list.
3. At the top of the screen select Copy To: Handheld.
4. Highlight the program to copy (in this case it is CPLink).
5. Select the (Copy) button at the bottom of the screen.
6. If the program exists in RAM on the handheld, you will be asked if you want to
replace it. If it doesn't already exist - go to step 8.
7. If yes is selected, the old version will be overwritten with the version from the SD
card.
8. Select (Done) when the copy has completed.
The m125 and the m500 support Expansion Cards
while the m100 and m105 handhelds do not.
