Your BrailleNote QT automatically manages its power usage to give you the maximum life from
the battery. It will enter into hibernate mode after about 10 minutes of inactivity and stay in that
mode until you next press a key. You can help by switching off your BrailleNote QT when you are
not going to be using it for a while. Remember that you can switch your BrailleNote QT off and on
without affecting your work in any way and your BrailleNote QT resumes from where you were
when you switched off.

Charging the Battery.
To charge the battery, simply plug the AC adapter in and the BrailleNote QT looks after the battery
charging itself. There is no chance of overcharging and damaging your batteries, so don't be afraid
to leave the AC adapter connected at all times. Once the battery is fully charged, only a very small
amount of power is used. Leaving the AC adapter connected ensures that the BrailleNote QT
remains fully charged ready for when you next need to use it on battery power.

If the battery is flat and the AC adapter is connected, the battery is fast charged in about 4 hours.
Charging takes less time if the battery is only partially discharged. Note that you can charge the
battery and use the BrailleNote QT simultaneously, however it may take up to 8 hours to reach full
charge. To ensure that the battery charges correctly, only charge in ambient temperatures between
41 and 95 degrees Fahrenheit, that is, 5 to 35 degrees Celsius.

If the ambient temperature is too high, there is a risk that the battery will not charge. We therefore
recommend that if the temperature is nearing 95 degrees Fahrenheit, that is, 35 degrees Celsius,
leave your BrailleNote QT to charge in a cool place with the carry bag lid open. There is no danger
in doing this, and no harm can come to your BrailleNote QT!
