Using expansion cards
The expansion slot on your Treo enables you to add Secure Digital (SD™) cards and
MultiMedia™ Cards (MMC) to extend the storage capacity of your Treo. For example,
SD or MMC expansion cards can store:
•pictures
•MP3 audio files
•games
•eBooks
• applications
• databases
... and more
Although expansion cards are sold separately, your Treo includes a mock, non-
functional card inside the expansion slot. When you’re not using a functioning card,
reinsert the mock card that came with your Treo to protect the e xpa nsion sl ot openi ng
and to keep the slot clean.

Inserting and removing expansion cards

1. Press down and release the mock card.
2. After the expansion slot ejects the mock card, remove the card from the slot.
SD cards are faster than
MMC cards for reading and
writing data.
