Notes on connections
B
Read the instruction manual for each peripheral device carefully before connecting it.
B
Turn off the power supply for all peripheral devices before making any connections.
B
If the cables necessary for connection are not included with the peripheral device or
available as an option, you may need to prepare a proper cable for the device concerned.
B
If there is a lot of jitter in the video signal, the projected image may flicker. In such cases,
it will be necessary to connect a TBC (time base corrector).
B
Refer to the list on page 62 for details on compatible signals which can be input to the
projector.
B
Only one audio system circuit is available for the AUDIO IN L-R connectors, so if you
change the audio input source, you will need to remove and insert the appropriate plugs.

B Remove the battery if not using the remote control unit for long periods.
B Use only CR2025 batteries as replacement batteries.
B If the remote control unit is held so that it is facing directly in front of the
remote control signal receptor, the operating range is within
approximately 7 m (23´) from the surfaces of the receptor. Furthermore,
the remote control unit can be operated from an angle of ±30° to the left
or right and ±15° above or below the receptor.
B If the buttons on the remote control unit are kept pressed, the battery
power will be consumed rapidly.
B If there are any obstacles in between the remote control unit and the
receptor, the remote control unit may not operate correctly.
B If strong light is allowed to shine onto the remote control signal receptor,
correct projector operation may not be possible. Place the projector as
far away from light sources as possible.
B
If facing the remote control unit toward the screen to operate the projector,
the operating range of the remote control unit will be limited by the amount
of light reflection loss caused by the characteristics of the screen used.
