1 when writing data to an expansion card, wait for your handheld to complete the operation before removing the card from the slot. this prevents data corruption or accidental damage to the expansion card.

    2 you can install applications to an expansion card after performing an initial hotsync operation. see "installing files and add-on applications"in chapter 4 for information. for optimal performance, we recommend that you do not install more than 50 applications to a single expansion card.

    3 reading and writing information on an expansion card uses more battery power than performing the same task on your handheld. if you have ample storage space on your handheld, consider copying the information to your handheld.

    4 when your handheld's battery level becomes very low, access to the expansion card may be disabled to protect your data. if this occurs, recharge your handheld as soon as possible.
