1 General Safety Information 
Do  not  make  any  changes  or  settings 
that are not described in this user manual. 
Physical injury or  damage  to the device 
or loss of data can result from improper 
handling. Take  note of all warnings and 
safety notes indicated. 
Setting up the Device 
The device is exclusively for indoor use. 
To avoid possible  injuries  to persons  or 
damage  to the  device  itself, the device 
should  be placed  securely on a  stable, 
flat surface. Position all cables in such a 
way that no one will stumble on them. 
Do not plug in the device in moist rooms. 
Never  touch  the  mains  cable  of  the 
mains connection with wet hands. 
The  device  must  have  sufficient 
ventilation and may not be covered. Do 
not put your device in closed cabinets  or 
boxes. 
Do  not  place  the  machine  on  soft 
surfaces such as  tablecloths  or carpets 
and  do  not  cover  the  ventilation  slits. 
Otherwise  the device could overheat or 
catch fire. 
Protect the device against direct sunlight, 
heat, large temperature fluctuations and 
moisture. Do not place the device in the 
vicinity  of  heaters  or  air  conditioners. 
Observe the information on temperature 
and humidity in the technical data. 
When  the  device  is  running  for  a  long 
period of time, the surface becomes hot 
and  a  warning  symbol  appears  on  the 
projection.  Then  the  device  switches 
automatically to  stand  by mode when it 
gets too hot. After the device has cooled 
down,  you  can  continue  playback  by 
pressing any key. 
Do  not  allow  liquids  to  enter  into  the 
device.  Switch  off  the  device  and 
disconnect  it  from  the  mains  supply  if 
liquids  or  foreign  substances  end  up 
inside  the  device.  Have  the  unit 
inspected  by  a  technical  service 
department. 
Always  handle  the unit with  care. Avoid 
touching the lens. Never place heavy or 
sharp  objects  on  the  projector  or  the 
power cable. 
If  the  projector  gets  too  hot  or  emits 
smoke,  shut  it  down  immediately  and 
unplug the power cable. Have the device 
examined by  trained professionals  at a 
technical service location. To prevent the 
spread  of  fire,  open  flames  should  be 
kept away from the device. 
Under the following conditions, a layer of 
moisture  can  appear  inside  the  device 
which can lead to malfunctions: 
※  if the device is moved from a cold to a 
warm area; 

4 
※  after a cold room is heated; 
※  when this device is placed in a damp 
room. 
Proceed as follows to avoid any moisture 
build-up: 
1 Seal this device in a plastic bag before 
moving it to another room, in order for it 
to adapt to room conditions. 
2 Wait one to two hours before you take 
the device out of the plastic bag. 
The device should not be used in a very 
dusty  environment.  Dust  particles  and 
other  foreign  objects  may  damage  the 
unit. 
Do  not  expose  the  device  to  extreme 
vibrations.  It  may  damage  the  internal 
components. 
Do  not  allow  children  to  handle  the 
device without supervision. The packing 
materials should be kept out of the hands 
of children. 
Power Supply 
Use  only  the  enclosed  power  adapter 
(see chapter Appendix/ Technical Data). 
Check whether the mains voltage of the 
power supply matches the mains voltage 
available at the setup location. 
The adapter could be connected to 
IT power distribution systems. 
The  capacity  of  the  battery  diminishes 
with time. If the device functions only with 
the power supply, the battery is defective. 
Contact an authorized service center to 
replace the battery. 
Do not try to replace the battery yourself. 
Incorrect handling of the battery or using 
the  wrong  type  of  battery  can  cause 
damage to the device or cause injury. 
Switch  the  device  on  or  off  before 
removing  the  power  supply  from  the 
socket. 
Turn  off  the device and  remove it from 
the  power  supply  before  cleaning  the 
surface. Use a soft, lint-free cloth. Never

  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.
