Connect BrailleStart-UpPage 141. Start-up sound: This is a low tone which sounds during start-up. If the start-upsound is preceded by a very short, high tone, followed by a pause, then theConnect Braille is in work mode.2. Warning signal: This consists of two rapid, consecutive tones and may sound, forexample, when you have reached the bottom of the menu and try to go down.3. Error signal: This is a series of warning signals, which may be emitted, for example,if no microSD card is inserted.Note: You can specify which types of acoustic signals you want the Connect Braille to emit(see chapter 5.1.4 and 5.1.4.4). In this manual, the assumption is that this setting is set to'action Confirmations'. This is also the factory default.3.3.3 System MessagesThe Connect Braille will display messages to indicate the successful completion of anoperation or to alert you to possible operating errors. If the message is an error messageor if it is an important message, a beep will also sound. We recommend carefully reviewingthese messages before continuing with your work. They frequently contain instructions onhow to proceed.Most error messages will be in your local language however, there are some systemmessages that are only provided in English. In regard to these messages, all messagesbeginning with 'fatal', 'fer:', 'error' or 'wrn:' should be attended to.After you have read the message, you can exit by pressing [TLC], which in most cases willreturn you to the place from which the message was initiated. If the message text does notfit on the Braille display, you can scroll through it by means of the [TD] and [TU] keys.In chapter 12 you will find a list of the most important messages with explanations.3.3.4 Check BoxesCheck boxes are switches that can be in either an "on" or "off" state. A check box consistsof a symbol indicating its state, and a designation. The symbol "[X]" indicates that thecheck box is "on", or active, whereas "[ ]" is an inactive, or "off" check box.Toggling the state of the check box between on and off is accomplished by pressing [SPC]or [TRC]: the state is toggled upon each keystroke. Alternatively, you can also press thecursor routing key above the check box to toggle it. As soon as you move on to a newmenu item, the last state indicated by the check box remains in force. However, thesettings are not permanently saved until the 'Options' menu is closed.Check boxes are used for controlling your Connect Braille's functions and are found in theOptions menu. For example, you can choose either 6 dot or 8 dot Braille this way.Note:If the Connect Braille is turned off without having closed the Options menu, the lastchanges to be entered will be lost. The new settings are saved only upon exiting theOptions menu!
