GMalfunction 
Immediately  stop  using  the 
projector  if  the  screen  appears 
abnormal,  if  sound  is  not 
produced,  or  if  any  other 
abnormal  operation  occurs  even 
though  you  are  operating  the 
projector  correctly.  Continued  use 
creates  the  risk  of  fire  and 
electric  shock.  Immediately 
perform  the  following  steps.

observe  the  following  precautions. 
 Make  sure  that  you  use  a 
power  source  with  the  same 
voltage  as  that  specified  for 
the  projector. 
 Do  not  overload  a  power  outlet 
with  too  many  devices. 
GPower  cord
A  damaged  power  cord  creates 
the  risk  of  fire  and  electric  shock.
Make  sure  that  you  always 
observe  the  following  precautions. 
 Never  place  heavy  objects  on 
the  power  cord  and  never 
expose  it  to  heat.
 Make  sure  the  power  cord  is

Safety  Precautions
GWater  and  foreign  matter
Never  allow  water  to  get  on  the 
projector.  Water  creates  the  risk 
of  fire  and  electric  shock.
Never  place  a  vase  or  any  other 
container  of  water  on  top  of  the 
projector.  Water  creates  the  risk 
of  fire  and  electric  shock.
Water  or  other  liquid,  or  foreign 
matter  (metal,  etc.)  getting  into 
the  projector  creates  the  risk  of 
fire  and  electric  shock.  Should 
anything  get  inside  the  projector, 
immediately  perform  the  following 
steps.
1. Turn  off  the  projector.
2. Unplug  the  projector.
3. Contact  your  original  dealer  or 
authorized  CASIO  service 
center.
GDisassembly  and  modification
Never  try  to  take  the  projector 
apart  or  modify  it  in  any  way. 
The  projector  contains  a  large 
number  of  high-voltage 
components  that  create  the  risk 
of  electric  shock  and  burn  injury.
Be  sure  to  leave  all  internal 
inspection,  adjustment,  and  repair 
up  to  your  original  dealer  or 
authorized  CASIO  service  center.
GDropping  and  impact 
Continued  use  of  the  projector 
after  it  has  been  damaged  by 
dropping  or  other  mistreatment 
creates  the  risk  of  fire  and 
electric  shock.  Immediately 
perform  the  following  steps.
1. Turn  off  the  projector.
2. Unplug  the  projector.

3. Contact  your  original  dealer  or 
authorized  CASIO  service 
center.
GDisposal  by  burning
Never  try  to  dispose  of  the 
projector  by  burning  it.  Doing  so 
can  cause  an  explosion,  which 
creates  the  risk  of  fire  and 
personal  injury.
GLooking  into  the  lens  or  vents 
while  lamp  is  on
Never  look  directly  into  the  lens 
or  vents  while  lamp  is  on.  The 
strong  light  emitted  by  the 
projector  creates  the  risk  of  eye 
damage.
GBlocking  the  vents
Never  allow  the  intake  vents  (on 
the  bottom  or  back  of  the 
projector)  or  the  exhaust  vents 
(on  the  side  of  the  projector)  to 
become  blocked.  Doing  so 
causes  internal  heat  build  up, 
which  creates  the  risk  of  fire  and 
breakdown  of  the  projector. 
Touching  the  projector  while  it  is 
hot  creates  the  risk  of  burn 
injury.  Make  sure  that  you  always 
observe  the  following  precautions.
 Allow  at  least  30  cm  (11.8 
inches)  between  the  projector 
and  walls.
 Do  not  insert  the  projector  into 
any  space  where  air  circulation 
is  poor.
 Never  cover  the  projector  with 
a  blanket  or  any  similar  item.
 Never  use  the  projector  on  a 
carpet,  blanket,  towel,  or  other 
soft  material.
 Never  stand  the  projector  up 
on  either  end  during  use.
GHeavy  objects
Never  place  heavy  objects  on  the 
projector  or  climb  on  top  of  the 
projector.  Doing  so  creates  the  risk  of 
fire  and  electric  shock. 
GWater
Never  locate  the  projector  in  a 
bathroom  or  anywhere  else  there  is  the 
chance  that  it  will  be  splashed  with 
water. 
GUnstable  location
Never  place  the  projector  on  an 
unstable  surface  or  on  a  high 
shelf.  Doing  so  can  cause  it  to 
fall,  creating  the  risk  of  personal 
injury. 
GUsing  the  projector  on  a  base 
with  casters
Whenever  using  the  projector  on  a  base 
that  has  casters,  make  sure  that  you 
lock  the  casters  when  not  moving  the 
base. 
GLightening
During  a  lightening  storm,  do  not  touch 
the  plug  of  the  projector’s  power  cord.
Safety  Precautions
GProjector  cabinet 
Never  open  the  projector’s 
cabinet.  Doing  so  creates  the  risk 
of  electric  shock.
GCleaning
Before  cleaning  the  projector,  be 
sure  to  turn  it  off  and  unplug  it 
from  the  power  outlet.  Failure  to 
do  so  creates  the  risk  of  electric 
shock. 
GExhaust  vents
The  exhaust  vents  become  very  hot 
while  the  projector  is  running.  Never 
touch  them.  Doing  so  creates  the  risk 
of  burn  injury.  The  areas  near  the 
exhaust  vents  also  become  quite  hot. 
Never  locate  objects  made  of  plastic  or 
other  heat-sensitive  materials  near  or 
under  the  projector.  Doing  so  creates 
the  risk  of  deformation  and  discoloration 
of  the  object.
GLens  cover
Be  sure  to  open  the  lens  cover  before 
turning  on  the  projector.  Never  close  the 
lens  cover  while  the  projector  is  in  use.
GLocation
Never  locate  the  projector  in  any  of  the 
following  types  of  locations.  Doing  so 
creates  the  risk  of  fire  and  electric 
shock.
 Near  an  area  subject  to  strong 
vibration
 An  area  subject  to  large 
amounts  of  moisture  or  dust
In  a  kitchen  or  other  area 
exposed  to  oil  smoke
 Near  a  heater,  on  a  heated 
carpet,  or  in  an  area  exposed 
to  direct  sunlight
 An  area  subject  to  temperature 
extremes  (Operating 
temperature  range  is  5°C  to 
35°C  (41  to  95  °F)).
6
GBackup  of  important  data
Be  sure  to  keep  separate  written 
records  of  all  data  stored  in 
projector  memory.  Memory  data 
can  be  lost  due  to  breakdown, 
maintenance,  etc.
GLens  effect
Never  have  an  aquarium  or  any  other 
object  that  produces  a  lens  effect  in 
front  of  the  projector  while  the  lamp  is 
on.  Such  an  object  creates  the  risk  of 
fire.
GLens
Never  touch  the  lens  with  your  hand.
