5.2. Configuration options
There is a file named „CONFIG MILESTONE.TXT“ located on the internal memory of your
Milestone 112 Ace. This file can be used to modify the configuration of Milestone 112 Ace.
The text file can be opened and modified with a text editor on your computer. The setting
possibilities are as follows:
To activate an audible notification before the device powers off:
Go to the entry “enable_feature offsound”. Replace “0” by a value between 1 and 200. For
example, enter 30 and Milestone 112 Ace will play a short signal 30 seconds before it
powers off. The value “0” disables this feature.
To activate optional folders:
Go to the entry “folders”. Replace “no” by “yes” and 5 folders to store your data will be
accessible on the internal memory of your Milestone 112 Ace.
To activate folder names:
Go to the entry “folder_names”. Replace “no” by “yes” and labeling of folders with a
recorded name becomes possible. A folder is labeled with the following button
combination: Push and hold “Rec” and after a click in addition push and hold “Mode”. Keep
holding both buttons and start speaking the name after the sound sequence “low pitched-
high pitched”. You finish the record by releasing both buttons. This is signaled by the
sound sequence “high pitched-low pitched”.
To increase the speed of prompts:
Go to the entry „prompt_speed“. Replace “100” by a value up to 150. This feature enables
you to increase the announcement speed of menu prompts. For example, if you insert 150
the speed level of the menu prompts will be at 150%. Save and close the file when done.
5.3. Protecting your Milestone 112 Ace
