NOTE
• When using the remote control, the optimal operation range is 6 meters or less
(left/right) and within a 30 degree arc of the remote control IR receiver.
•
If a cable is connected to the back port, the optimal operating range is 3 meters
or less (left/right) and within a 30 degree arc of the remote control IR receiver.
• For seamless operation, do not block the IR receiver.
•
When you carry the remote control in the portable bag, make sure that
the buttons on the remote control are not pressed by the projector, cables,
documents, or any other accessories in the bag. Otherwise, it may significantly
reduce the battery life.
