Before Using the Remote Control
TIP
• Do not allow sunlight or light from fluorescent lamps to shine
directly onto the projector's remote control light-receiving areas,
otherwise it may interfere with the reception of signals from the
remote control.
• When not using the remote control, set the [R/C] switch on the
remote control to "OFF". If you leave the [R/C] switch at "ON", it
will consume battery power.
• If a button on the remote control is pressed down for more than 1
minute while the [R/C] switch is at "ON", the signal for that button
operation will stop being transmitted (the remote control will change
to sleep mode). The purpose of this is to prevent the batteries from
being consumed due to something being placed on top of the remote
control.
When the button is released, normal remote control operation will
resume.
• If it is within a total of about 10 m (30 ft.) in the distance from the
remote control to the screen and from the screen to the projector, the
remote control may work by pointing it towards the screen because
the signals are reflected by the screen and sent to the projector.
However, the operating range varies depending on the status of the
screen.
• If you would like to ensure that remote control operations work
properly from a distance, use the optional remote control cable set to
connect the [Remote] port of the remote control to the projector's
[Remote] port.
