General operation
Power on/off
• Power on: Press and hold
the power button until the logo
appears. Then there will be
splash screen and main screen.
Hold down the
icon and
drag it to the right onto the icon
representing an open lock to
unlock the device.
• Sleep Mode: Sleep mode is
convenient for regular use of the
device. In this mode, the device
is active, but the display is turned
off at the same time, and the main
screen is locked. This allows you
to instantly access your operating
system, while at the same time
excludes accidental pressing on
the display and saves energy. To
go into sleep mode or out of it,
briefly press the power button.
• Turn off: Press and hold
the power button until a prompt
appears asking to switch off the
device. Click “OK” to shut down.
In case of low battery
the unit can be switched off
automatically after notifying the
user about the problem. Moreover,
all unsaved data may be lost.
To avoid this, save your open
documents, close all applications
and connect the smartphone to a
power source.
Reboot the device
If the device does not turn on/
off and ignores any input, take the
battery out to reboot the system.
Inserting and removing
the SIM card
Turn off the smartphone;
remove the back lid and the
battery and unplug other external
power supplies. Insert the SIM card
into the SIM holder as shown on
the panel in the smartphone.
When you need to remove the
SIM card, turn off the smartphone,
remove the battery and then
remove the SIM card from the
holder.
Warning: Turn off your
smartphone before removing the
SIM card. Never insert or remove
the SIM card when an external
power supply is connected, as
this may cause damage to the
SIM card.
