Humanware explore 8 User Manual page 24

The lightning bolt icon means your device is
being charged. The number to the right
represents the percentage of battery charge
remaining.
Due to lower voltage, charging from the
computer USB may be slower. In some cases,
your device may not charge at all depending
on the amount of power supplied by the
computer. The most effective way to recharge
the device is to use the supplied USB cable
connected to the USB charger and recharge it
from a household power outlet.
Although it may lengthen the charging time,
the device can be used when it is recharging.
Please note that if the battery is fully
discharged or hasn't been used for a very long
period, there will be a delay of up to a few
minutes before the device shows any activity.
This is normal.
Also note that like all electronic devices, your
explorē 8 will become warm when in use or
when being charged – this is normal.
