charging (what we call "docking the keyboard"). It takes several minutes to start working if
the keyboard is completely discharged.
Key descriptions and layout
The key names are used throughout this manual to describe commands and provide
general operating information. See the
graphic insert
for reference.
P1 .. P8
=
Perkins keys 1..8
Esc
=
Escape keyboard (upper-left key)
TAB
=
Tab key (below Escape key)
BS
=
Backspace key (upper-right key)
Ent
=
Enter key (below Backspace key)
SP
=
Space (long key in lower part of keyboard)
Command Key
(round key in the middle of keyboard
4-way manipulator
in the lower-
right part of the keyboard)
As you may notice, the keys are placed similarly to any
regular PC keyboard
. That serves
to introduce important computer concepts that the young user will use in the future.
To navigate the page up and down, you may use the 4-way manipulator. As you can see
from the above description - there is no manual paper advance knob or wheel in the unit.
You need to use the electronic 4-way manipulator, or manually release the paper by lifting
the paper lever. After setting the paper lever back to the operating position, the unit will
assume it is at the beginning of a page now.
Additionally, the dial used to set the volume (on the right side of your unit) when used while
Space is pressed will
move the paper in small steps
. This helps adjust the vertical paper
position more finely.
One-handed keyboard mode
One-handed mode is meant for persons with multiple disabilities who can't use both hands
to press multiple keys at the same time – the regular way of using a Perkins-type braille
keyboard. When this mode is on, press space after the dots that build each character. For
example:
To type the letter u, you do not have to press dots 1, 3, 6 together. You can press the
dot keys separately in any order. For example, using one finger, press dot 3, then dot
1, then dot 6. Then press space to emboss the character.
To turn the one-handed mode on, you need to use the Menu/Keyboard/One hand mode or
enter the {ku} command. For more information on entering commands, please see the
"
Menu and commands - how to use them"
section below.
To return to standard two-handed keyboard use, remember to use Command, dot 1, dot 3,
space, dot 1, dot 3, dot 6, space, and enter; or go into the Menu/Keyboard/One hand
mode and press Enter to toggle back to normal mode.
Using an external QWERTY keyboard
An external USB computer keyboard can be connected to either one of the USB
connectors on the right side of your Mountbatten Brailler Tutor. It is a convenient tool for
communication between a blind MBT user and persons who don’t know braille. Typing
characters on the QWERTY keyboard in a standard setup will produce braille on paper.
And you can also braille with contractions (when you turn
forward translation
on).

features of MB Tutor/Forward Translation Settings.
