Setting
Remote control
This projector provides two different remote control codes; 
the factory-set, initial code (Code 1) and the secondary code 
(Code 2). This switching function prevents remote control 
interference when several projectors or video equipment 
are operated at the same time.  
When the projector is operated in “Code 2,” both the 
projector and the remote control must be switched to 
“Code 2.”
 
To change the code for the projector:
Select either “Code 1” or “Code 2” in this Setting Menu.
To change the code for the remote control:
Press and hold both the MENU and IMAGE buttons 
together for more than 5 seconds. After changing the code, 
make sure the remote control operates properly.

case, switch the code on the remote control to fit the 
code on the projector.
•  If the batteries are removed from the remote control for a 
long period of time, the remote control code will be reset.

How to Use the Antitheft Alarm Function
Antitheft alarm function is provided to prevent the projector from being stolen. When this function is set to 
“On,” the alarm rings as an unauthorized person tries to move the projector.
To activate the Alarm function for the first time after purchase, you must turn on the power once. 
Press the F button three times to turn the alarm function 
on. The ALARM indicator blinks for a few seconds and the 
projector enters the warning mode. (If the battery is not 
charged enough for the alarm function to operate normally, 
it bleeps and the Alarm indicator will blink red every 20 
seconds.)
During the Antitheft alarm function is on, the projector 
emits a low-pitched sound when it detects vibration.
When the projector does not detect vibration for a few 
seconds after the sound, it goes back to the warning mode.
When the projector detects more vibrations after the low-
pitched sound, the alarm starts ringing.
The Alarm operating configuration (Alarm volume, 
Sensitivity, and Ringing time) can be selected in the menu. 
See page 57.
Set the alarm
Release the alarm setting
✔Note:
  •This function is not a guarantee against stealing.
  • The alarm does not ring while the AC power cord is connected to an outlet even if the projector detects 
vibrations.
  •The alarm will stop, as the AC power cord is connected to an outlet, except when the battery cover is open.
  • Pressing the buttons is always accompanied by a sound. If no sound is produced after pressing a button, 
you need to press it again.
Set and release the Antitheft alarm function
✔Note:
  • You can test the alarm sound without setting the alarm 
function. Press and hold the F button, then the alarm 
starts ringing. The duration of the alarm sound is the 
same as the “Ringing Time” setting (p.57).
  • If you want to stop the alarm while it is ringing, insert 
the AC power cord to an outlet or press the F button and 
enter the four-digit PIN code number.
The Alarm function is operated by a built-in rechargeable 
battery.  The alarm will not work properly if the battery is not 
charged enough. See page 58 for details.
Press the F button and enter the four-digit PIN code number 
within about 10 seconds. (The default PIN code is set to 
“1111.”) When the alarm is released, you will hear a high-
pitched confirmation sound.
When you enter an incorrect PIN code, you will hear a low-
pitched sound. If you enter an incorrect PIN code three  
times in a row, the alarm will start ringing.
The Alarm setting and release and PIN Code change can be 
made without an AC power connection.

Charge the built-in battery pack
As long as the AC power cord is connected, the built-in 
battery for Alarm function is being charged at all times. 
While charging the battery, “Charging” is displayed in the 
menu. 
The “Charging” appears dimmed when the battery is fully 
charged or if charging malfunction occurs. ✔Note:
 •    The PIN code and settings you have changed are 
effective even after the battery is changed.
  • When replacing the rechargeable battery pack, protect 
the infrared remote receiver with a soft cloth to avoid 
damaging it.
  • Unplug the battery connector if you carry your 
projector frequently and use the carrying case. If you 
do not unplug the battery connector, the alarm may 
be triggered when the Alarm buttons are accidentally 
pressed inside the carrying case.
  •    The built-in battery pack is a consumable supply.  Each 
time you repeat discharge and recharge the battery, 
the battery life will decrease.  The battery will gradually 
discharge when left for long periods even without use.  
If the full-charged battery is left at normal temperature 
of 95º F (25º C), the battery will gradually discharge and 
can be non-rechargeable after about 7 months.  The 
battery life may vary from battery to battery according 
to the environment of use.
Remove the screw and 
open the battery cover.
Install the battery, then put back the battery cover 
and secure it with the screw.

SAFETy PRECAUTIONS FOR SANy O Ni-MH BATTERy PACK
Observe the following precautions when handling the built-in battery pack of the projector:
 l  MAKE SURE THAT THE BATTERY PACK IS INSTALLED IN THE PROJECTOR WHEN RECHARGING. 
USING THE CHARGERS OTHER THAN THE PROJECTOR MAY CAUSE EXPLOSION OR A FIRE.
  l  The rechargeable battery pack is for use exclusively with this projector. Do not use in other products or 
this may cause accident.
  l  Do not throw the battery into fire or heat it. Doing so may cause an explosion or fire.
  l  Never attempt to disassemble, modify, reconstruct, or solder lead wires directly on to the battery.
  l  Do not drop or subject to strong forces. Doing so may cause the battery to leak fluid or explode.
  l  Do not expose to direct sunlight or high temperatures. This may degrade battery performance or cause 
leakage.
  l  Avoid contact with water or liquid. Exposure to water or liquid could result in battery corrosion or 
damage.
  l  Keep out of reach of children. They may accidentally swallow the battery. 
  l  Do not short-circuit battery terminals with metal objects. Do not store with metal objects or in a metal 
case.
  l  The rechargeable battery pack has a limited number of charge cycles and eventually need to be 
replaced. If it can no longer be recharged, stop charging immediately and replace it with new one.
  l  Recharge the battery in a place where the temperature is always between 32˚F to 104˚F (0˚C to 40˚C). 
Charging in the temperature out of this range may result in fluid leak, heat generation, or shortening 
battery life.
  l  If you do not use the projector or the Antitheft alarm function for a long period of time, remove the 
battery from the projector and store it in a place where the temperature is always between –4˚F to 86˚F 
(–20˚C to 30˚C).
  l  If a battery leaks and fluid comes in contact with skin, this may cause skin irritation. Flush the affected 
area thoroughly with water.
  l  If a battery leaks and fluid gets in contact with eyes, wash your eyes with water immediately and seek 
medical attention.
  l  Risk of an explosion if battery is replaced by an incorrect type.
  l  Dispose of used batteries according to the instructions or your local disposal rule and guidelines.

The WARNING indicator shows the state of the function which protects the projector. Check the state of the 
WARNING indicator and the POWER indicator to take proper maintenance. Indicators
Warning Indicator
The projector is shut down and the WARNING 
indicator is blinking red.
When the temperature inside the projector reaches a
