Battery maintenance
The capacity of the battery diminishes
with time. To prolong the life of the
battery, please observe the following
instructions:
 Without a power supply, the device
operates itself through the built-in
battery. When the battery does not
have sufficient capacity, the device
will turn off. Connect the device with
USB cable on an USB port.
 When the device is in low battery,
the battery icon in the status bar
turns red.
 When the device overheats after
running for a long period of time, a
warning icon will appear on the
projection. The device behaves as
follows:
1 The speed of the fan reaches the
highest level.
2 When the brightness is set to a
maximum level, a overheat
Icon will appear in the status bar and
then the brightness will be automatically
set to a minimum level.
3 When the brightness is set to a
minimal level, a overheat icon will show
for three seconds in the middle of the
screen. Then the device will turn off
automatically.
After the device has cooled down, you
can continue playback.
 Use the device at least once a
week.
 Charge the battery regularly. Don’t
store the device with a completely
discharged battery.
 If the device is not used for several
weeks, discharge the battery a little
by using the device before storing
it.
 If the device can only work via the
USB connection or with the power
supply, it proves that the battery
has lost effectiveness.
 Keep the device and the battery
away from heat sources.
