Charging The Device - Baum VarioUltra 20 User Manual

10 minutes of inactivity. It's possible to lengthen this time default, or
switch it off completely so that your device only switches off when you
press the power button. Suspend mode will not happen if you are
actively connected to a USB or Bluetooth device.
To turn VarioUltra off completely, press and hold system key S4 and
then tap and release the power button. VarioUltra will vibrate and power
off. If VarioUltra is connected to a power supply or connected to a
computer via USB, the braille display will show a row of braille cells with
all dots showing on each cell, indicating the charge level of the battery. If
VarioUltra is not connected to anything, the braille display will be blank
when switched off completely. Switching VarioUltra off completely is
recommended during extended periods when it will not be used. This will
help preserve battery life over longer periods of time.

1.4 Charging the Device.

VarioUltra has an internal Lithium ion battery that is charged via the
micro USB to standard type A USB cable. The micro USB end of the
cable that inserts into VarioUltra has a connector that is longer on one
side than the other. The longer edge needs to be on top to fit in
VarioUltra; a helpful way to know when the longer edge is facing up is to
feel for 2 small bumps on toward the outer edges. If the bumpy side is
facing up, you have the cable facing the right way. Connect the other
end of the cable into a USB plug, into the USB port of a computer, or to
a USB power adaptor (800 - 2000 mA, 5 V).
Note:
Charging VarioUltra takes approximately 2.5 hours when plugged
directly to an electrical outlet. Connecting via USB to devices such as a
computer takes more time – as much as two times longer.
The battery should last between 8 and 12 hours depending on whether
you are connected to Bluetooth devices, etc. Running in Braille
Notetaker mode with Bluetooth switched off will last the longest.
Conversely, running in Braille Display mode while actively connected via
Bluetooth to other devices will last the least amount of time.
If the battery drains completely, connect VarioUltra to an external power
source using the USB plug and USB cable that came with your device.
Whenever the battery drains completely, connecting VarioUltra to a
power source will not immediately bring it back to life. Please wait a few
