2 BrailleNote Apex QT Hardware.
This chapter provides a general overview of the BrailleNote Apex QT's various hardware features.
2.1
The Battery.
The BrailleNote Apex QT can operate from its internal rechargeable battery or from its AC adapter.
The length of time you can run the BrailleNote QT from a fully charged battery is typically between
10 and 12 hours before it becomes flat. Activities like embossing, e-mailing and using ports or
wireless connectivity increase the drain on the battery. Storage cards and USB devices that draw
their power from the BrailleNote QT's battery, also reduce the available battery life.

displays the following message:
"Battery is critical."
If this message is displayed you should act within the next minute or your BrailleNote QT may
switch itself off. The time available to switch off may be as little as 1 minute but it is typically 5 to
10 minutes if you are not using high current accessories. You have two options. You can connect
the AC adapter and carry on working indefinitely, or you can save your current work and switch
off. To save your work, just return to the Main Menu. If the BrailleNote QT switches itself off, it
cannot be switched on again until it is powered from the AC adapter.

If the battery becomes flat, the BrailleNote will switch itself off and will not switch on again until
you connect the AC adapter. If you connect the AC adapter within an hour or two you will not lose
work that was in progress and your BrailleNote will resume where it left off. However, if you leave
it longer, any unsaved work may be lost. It is therefore important to heed the battery warnings!
