Internal Battery - Freedom 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 any other
control 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 routing
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.
Use the AC adapter supplied with your unit to charge the battery. The unit
takes three hours to charge using the supplied AC adapter even when
the Bluetooth connection is active. Charging time will be less if the battery
is not completely discharged before the display is plugged in. The Focus
will also charge while connected to a computer using the USB cable,
however, charging time will take longer than with the supplied AC
adapter. You can continue using the Focus while it is charging.
Caution: No user serviceable parts. Risk of High Voltage shock.
