To remove a memory card, push the card to release it from the
slot.
Encrypting files on memory cards
To prevent sensitive data on a memory 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 device. Files are encrypted as they
are copied or written to the memory card. Files already saved on memory cards before enabling
encryption are not automatically encrypted.
Note – Because the encryption key is stored on the device, encrypted files are only readable on the device on
which they are initially encrypted. It is not possible to read encrypted files on the storage card with any other
device, including another handheld device or an office computer.
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 memory 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 memory card:
1.
Tap /Settings/ System/Encryption.
2. Select the Encrypt files when placed on a storage card check box.
Note – Encrypted files appear as ordinary files on the device they were encrypted on. If the memory 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 card check box.
Note – Disabling encryption does not remove encryption from any existing files on the memory card, but
ensures that new files placed onto the memory card are not encrypted.
To encrypt files that are already stored on a memory card:
1. Copy the files to the device’s internal memory or to an office computer.
2. Ensure encryption is enabled on the device.
3. Copy the files back to the memory card. The files are encrypted as they are written to the
memory card.
To remove encryption from files so they can be read by other devices:
