Securing the projector
Using a security cable lock
The projector has to be installed in a safe place to prevent theft. Otherwise, purchase a
security cable to secure the projector. A security bar is located on the right side of the
projector. See item 10 on page 11. Insert a security cable to the opening of the security
bar and secure it to a nearby fixture or heavy furniture.
Switching input signal
The projector can be connected to multiple
devices at the same time. However, it can only
display one full screen at a time. When starting
up, the projector automatically searches for the
available signals.
Be sure the Display > Auto Source Search menu
is On if you want the projector to automatically
search for the signals.
To select the source:
1. Press . A source selection bar appears.
2. Press / until your desired signal is selected and press OK.
Once detected, the picture from the selected source will appear. If there is multiple
equipment connected to the projector, repeat steps 1-2 to search for another signal.
Shutting down the projector
1. Press and a confirmation message will
appear prompting you. If you don't respond in a
few seconds, the message will disappear.
2. Press a second time. The power indicator
flashes white, the projection light source shuts
down.
3. Once the cooling process finishes, the power
indicator becomes a steady blue and fans
stop. Disconnect the power cord from the
power outlet.
• The brightness level of the projected image will change accordingly when you switch between different
input signals.
• For best display picture results, you should select and use an input signal which outputs at the
projector’s native resolution. Any other resolutions will be scaled by the projector depending upon the
“aspect ratio” setting, which may cause some image distortion or loss of picture clarity.
• To protect the light source, the projector will not respond to any commands during the cooling process.
• Avoid turning on the projector immediately after turning it off as excessive heat may shorten light
source life.
• Light source life results will vary depending on environmental conditions and usage.
