How to Use the Antitheft Alarm Function
Antitheft Alarm Function
The Antitheft alarm function is to prevent the projector from being stolen. With this function on, the alarm rings
when an unauthorized person tries to move the projector.
Press the F button twice to turn the alarm function on. The
ALARM indicator blinks for a few seconds and the projector
enters the warning mode.
While the Antitheft alarm function is on, the projector emits
a low-pitched sound when detecting a vibration.
When the projector does not detect a 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.

• This function is not a guarantee against stealing.
• The alarm does not ring while the AC power cord is connected
even if the projector detects vibrations.
• Pressing the button is always accompanied by a sound. If any
sound is not produced after pressing the button, you need to press
it again.

pitched sound. If you enter an incorrect PIN code 3
times, the alarm starts ringing.
