Internal Battery - Freedom Scientific Focus 40 Blue User Manual

Internal Battery

The Focus 40 Blue contains an internal battery for Bluetooth operation.
While using the Focus over a Bluetooth connection, you will get
approximately 20 hours for typical usage. To check the battery status
while the display is in use, press the power button to display the
percentage of battery charge used. Press a cursor router or Navrow
button to return to normal operation.
When the battery is at 20 percent, 10 percent, and 5 percent respectively,
a low battery warning is displayed indicating it is time to plug in the AC
adapter. You can dismiss this message by pressing a cursor router or
Navrow button. In addition, once the battery drops below 10 percent, dots
seven and eight in the last five cells will show each percentage drop. For
example, when the battery is at one percent, DOT 8 in cell 40 will be
raised.
When charging the Focus, you must use the AC adapter supplied with
your unit. You can continue using the Focus while it is charging.
Caution: No user serviceable parts. Risk of High Voltage shock.
