5.1.6.4 Delete selected braille set (D)
If the loadable character set feature is used extensively, all slots will eventually be filled. In
order to delete a given Braille character set, please proceed as described below:
1. Activate the character set to be deleted in the menu item 'Braille character sets'.
2. Open 'Braille character sets' again and move through it to the end.
You will arrive at the menu item 'Delete selected braille set'. Once you have activated
this command, you will be asked whether you really want to delete the character set. If you
answer "Yes," the character set selected in the previous step will be deleted, and the
default character set will be activated.
5.1.7 Info (I)
You can check flash memory usage and the remaining charge and status of the batteries
in the 'Info' menu. You can also check the firmware version and serial number and
determine the configuration of the external keyboard.
5.1.7.1 Memory usage (M)
The Braille System contains 4224 KB of text memory, which equals text consisting of more
than 4 million characters (4,325,376).
The number of files that can be saved depends on their size. The file system's smallest
addressable unit (one sector) on the Braille System is currently approximately 8000
characters, and there are 512 sectors available to the file system. However, if you save a
file requiring less space than one sector, an entire sector will still be used for this file. We
therefore recommend collecting small notes together in one file if possible and marking
them with search marks.
After you select 'Memory usage', the size of free disk space is displayed in KB (kilobytes)
as follows: '4100 KB of 4224 KB (97%) free space'. You can exit this menu item by
pressing [ESC].
5.1.7.2 Battery statistics (B)
This menu provides various data regarding the batteries contained in your Braille System.
It consists of the three functions described below. This menu item is not available on the
Braille Star 80.
Please note that the values displayed by these functions are not updated dynamically. You
should close them by pressing [ESC] and reactivate them with [Enter] in order to display
updated information.
5.1.7.2.1 Capacity (C)
Capacity displays the batteries' charge in percent. A value of ≥99% represents completely
charged, 0% completely empty batteries. If a capacity of 50% is displayed, you will be able
to continue working on your Braille System for approximately 10 hours before having to
recharge the batteries.
