6.2. Advice
6.2.1. SD Memory Cards
6.2.1.1. For use with the M312 Ace we recommend media
SD cards made by SanDisk, Kingston, Transcend and Toshiba, which have been proven for use with the
M312 Ace very reliably.
6.2.1.2. Secure contents of a SD memory card
If you have important files stored on an SD card or to archive the data on the media in question, there can
be found on the side of the SD card a small switch, which allows you to prevent the deletion of files on this
card. M312 Ace observes this setting and can not delete files when this switch is set to write protection.
6.2.2. Configuration options for advanced users
In the main directory of the internal memory of Milestone 312 Ace is the file "CONFIG MILESTONE.TXT".
The values of these files can be modified via a USB connection on the computer to change the M312 Ace
configuration.
With this file you can enable or disable applications and features and make other custom settings. This
configuration file thus serves to adjust your device according to your wishes. If you delete this file, your
device falls back to the factory settings and all of your previously selected settings are lost (but not your
data, such as your voice records or books).
6.2.3. Protect your Milestone
Please protect your Milestone 312 Ace against strong force, humidity and water. The warranty does not
cover damage caused by improper handling, overload or opening the device.
6.2.4. Backing Up Your Data
Create a backup of your Milestone 312 Ace on another storage medium. You can never completely exclude
data loss, defect or theft, so you are well prepared and can still have access to your important documents.
It is therefore recommended to keep your data from the internal memory of Milestone 312 Ace on the
computer or an SD card for security.
To back up your data, connect the M312 Ace with your computer, as described in "USB connection and
then copy all folders from M312 to your computer, to ensure your personal data security.
