Connect Braille
Operation of the Connect Braille
Page 19
If the selected character set exists, it will be activated immediately, and you will be
returned to the main menu, menu item
'Braille character sets'
. The character set has
already been switched.
Note:
When using a custom character set, it is possible that messages or menu items suddenly
become partially or entirely unreadable. This may be due to one of the following causes:
•
The Braille character assignments in the custom character set do not correspond to
the assignments in the character set used for generating messages.
•
A custom character set contains errors. For example, if you have deleted a line in a
character table, the table no longer consists of 256 definitions. This causes all
character definitions following the deleted line to be moved up by one character.
This could cause the word "info," for example, to turn into "jmen".
If you cannot read the Connect Braille's messages at all, you have the following options:
1. Use the communications program HTCom's Monitor Mode. Under Monitor Mode,
the output is not affected by the Braille character set selected on the Connect
Braille. With the assistance of a sighted person or your screen reader's speech
output, you can monitor the output from the Connect Braille on the PC screen and
restore the standard character set. Switching into Monitor Mode is possible only if
the screen reader's access to the Braille display has been deactivated.
2. Create a situation where you are back in the main menu, so that you can navigate
from there to the menu item
'Braille character sets'
by using the [TD] key. If you
are sure that you are somewhere in the menu system, you can simply press the
[TLC] key several times, and then [TD] exactly five times. Then press [TRC], which
opens the submenu. Pressing [TRC] again will activate the default character set.
5.1.2.4 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.
5.1.3 Info (I)
You can check 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.
5.1.3.1 Battery statistics (B)
This menu provides various data regarding the batteries contained in your Connect Braille.
It consists of the three functions described below.
