Remote control About the remote control signal The remote control works with the projector's remote sensors. This projector has three remote sensors on the front, on the top, and on the back. The sensors can be respectively turned active or inactive using the "REMOTE RECEIV." in the SERVICE item of OPTION menu. Each sensor senses the signal within the following range when the sensor is active. The front and top sensors: 60 degrees (30 degrees to the left and right of the sensor) within 3 meters about. The back sensor: 40 degrees (20 degrees to the left and right of the sensor) within 3 meters about. NOTE • The remote control signal reflected in the screen or the like may be available. If it is difficult to send the signal to the sensor directly, attempt to make the signal reflect. • The remote control uses infrared light to send signals to the projector (Class 1 LED), so be sure to use the remote control in an area free from obstacles that could block the remote control's signal to the projector. • The remote control may not work correctly if strong light (such as direct sun light) or light from an extremely close range (such as from an inverter fluorescent lamp) shines on the remote sensor of the projector. Adjust the position of projector avoiding those lights. 30º 30º Approx. 3 m 30º 30º Approx. 3 m 20º 20º Approx. 3 m Changing the frequency of remote control signal The accessory remote control has the choice of the mode 1 or the mode 2, in the frequency of its signal.

About the remote control signal
The remote control works with the projector’s remote sensors. This projector has
three remote sensors on the front, on the top, and on the back.
The sensors can be respectively turned active or inactive using the “REMOTE
RECEIV.” in the SERVICE item of OPTION menu. Each sensor senses the signal
within the following range when the sensor is active.
The front and top sensors:
60 degrees (30 degrees to the left and right of the
sensor) within 3 meters about.
The back sensor:
40 degrees (²0 degrees to the left and right of the
sensor) within 3 meters about.
• The remote control signal reflected in
the screen or the like may be available. If it is
difficult to send the signal to the sensor directly,
attempt to make the signal reflect.
• The remote control uses infrared light to send
signals to the projector (Class 1 LED), so be
sure to use the remote control in an area free
from obstacles that could block the remote
control’s signal to the projector.
• The remote control may not work correctly if
strong light (such as direct sun light) or light
from an extremely close range (such as from
an inverter fluorescent lamp) shines on the
remote sensor of the projector. Adjust the
position of projector avoiding those lights.
NOTE
Changing the frequency of remote control signal
The accessory remote control has the choice of
the mode ± or the mode ², in the frequency of
its signal. If the remote control does not function
properly, attempt to change the signal frequency.
Please remember that the “REMOTE FREQ.” in
SERVICE item of OPTION menu of the projector
to be controlled should be set to the same mode
as the remote control.
To set the mode of the remote control, slide the
knob of the frequency switch inside the battery
cover into the position indicated by the mode
number to choose.
