Notes on connections
BRead the instruction manual for each peripheral device carefully before connecting it.
BTurn off the power supply for all peripheral devices before making any connections.
BIf 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.
BIf 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).
BRefer to the list on page 62 for details on compatible signals which can be input to the
projector.
BOnly 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.

Getting started
Insert the accessory lithium battery while making sure that the polarities are correct.
#While pushing the battery holder tab to the right, pull out the battery
holder.
$Insert the battery into the battery holder so that the + side is facing
upward.
%Insert the battery holder.
Preparation for the remote control unit
Push the tab
Pull out
Back side
Match the “+” surface of the battery
with the “+” marked side of the
battery holder.
NOTE:
BDo not drop the remote control unit.
BKeep the remote control unit away from liquids.
BRemove the battery if not using the remote control unit for long periods.
BUse only CR2025 batteries as replacement batteries.
BIf 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.
BIf the buttons on the remote control unit are kept pressed, the battery
power will be consumed rapidly.
BIf there are any obstacles in between the remote control unit and the
receptor, the remote control unit may not operate correctly.
BIf 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.
