incorrect or faulty connections may result in fire and/or electrical shock.
• Only use the power cord that came with the projector. If it is damaged, contact 
your dealer to newly get correct one.
• Only plug the power cord into an outlet rated for use with the power cord's 
specified voltage range.
• Never modify the power cord. Never attempt to defeat the ground connection 
of the three-pronged plug.
1. Connect the connector of the power cord to the AC inlet of the projector.
2. Firmly plug the power cord's plug into the outlet.

Putting batteries
WARNING  ►Always handle the batteries with care and use them only as 
directed. Improper use may result in battery explosion, cracking or leakage, 
which could result in fire, injury and/or pollution of the surrounding environment.
• Be sure to use only the batteries specified. Do not use batteries of different 
types at the same time. Do not mix a new battery with used one. 
• 
Make sure the plus and minus terminals are correctly aligned when loading a battery.
• Keep a battery away from children and pets.
• Do not recharge, short circuit, solder or disassemble a battery.
• 
Do not allow a battery in a fire or water. Keep batteries in a dark, cool and dry place.
• If you observe a leakage of a battery, wipe out the flower and then replace a battery. 
If the liquid adheres to your body or clothes, rinse well with water immediately.
1. Remove the battery cover.  
Slide back and remove the battery cover in the direction of the arrow .
2. Insert the batteries. 
 Align and insert the two AA batteries according to their plus and minus   
terminals as indicated in the remote control.
3. Close the battery cover. 
 Replace the battery cover in the direction of the arrow and snap it back into place.

Using the remote control
CAUTION  ►Be careful in handling the remote control.
• Do not drop or expose the remote control to physical impact.
• Do not get the remote control wet or place it on wet objects. It may result in 
malfunction.
• Remove the batteries from the remote control and store them in a safe place if 
you won’t be using the remote control for an extended period. 
• Replace the batteries whenever the remote control starts malfunctioning. 
• When strong lights (such as direct sunlight) or light from an extremely close 
range (such as from an inverter fluorescent lamp), hit the projector’s remote 
sensor, the remote control may cause to function. Adjust the direction of the 
projector to keep the light from directly hitting the projector’s remote sensor.
The remote control works with the projector’s remote sensor.
• The range of the remote sensor is 3 meters with a 60 degree range (30 degrees 
to the left and right of the remote sensor).
• Also  a  remote  signal  reflected  in  the  screen  etc.  may  be  available.  If  it  is  difficult 
to send a remote signal to the sensor directly, please try to use the reflected signal.
•  Since  the  remote  control  uses  infrared  light  to  send  signals  to  the  projector 
(Class1  LED),  be  sure  to  use  the  remote  control  in  an  area  free  from  obstacles 
that could block the remote control’s output signal to the projector.
