3. Insert the storage card into the storage card slot with the gold contacts facing

When you select the Save As option in an application, the storage card appears in the
list of available storage locations.
Note – Do not store required data or applications to a storage card if the card will be
removed. Data saved to a storage card is available only when the card is inserted in the
handheld.
To remove the storage card from the storage card slot, gently press the card in and then
let go. The card pops out.
Encrypting files on storage cards
To prevent sensitive data on an SD or SDHC card from being used if the card is lost or
stolen, files can be encrypted as they are placed on the card.
When encryption is enabled, an encryption key is stored on the handheld. Files are
encrypted as they are copied or written to the storage card. Files already saved on
storage cards before enabling encryption are not automatically encrypted.
Note – Because the encryption key is stored on the handheld, encrypted files are only
readable on the handheld on which they are initially encrypted. It is not possible to read
encrypted files on the storage card with any other device, including another GeoExplorer
6000 series handheld or an office computer.
C
CAUTION – If you reset the handheld to the factory default settings, the encryption key is
deleted and the handheld is no longer able to read any encrypted files on a storage card.
This means that any files you have encrypted are permanently locked and unreadable by
any device. To avoid being unable to read previously encrypted files, Trimble recommends
that you use another device, such as an office computer, as the primary location for
storing important data and to control the encryption of important files.
To enable encryption of files as they are written to a storage card:
1. Tap / Settings / System / Encryption.
2. Select the Encrypt files when placed on a storage cards check-box.
Note – Encrypted files appear as ordinary files on the handheld they were encrypted on. If
the storage card is inserted in another device, the files appear with a .menc file extension
and cannot be opened.
To disable encryption, clear the Encrypt files when placed on a storage cards check-box.
Note – Disabling encryption does not remove encryption from any existing files on the
storage card, but ensures that new files placed onto the storage card are not encrypted.
To encrypt files that are already stored on a storage card:
1. Copy the files to the handheld’s internal storage or to an office computer.
2. Ensure encryption is enabled on the handheld.
