When You Cannot Use the Interactive Function
If you cannot use the interactive function, follow the steps below in the specified order to troubleshoot
the problem.
Step Check item Solutions
1 Check the projector to make
sure that power is supplied
to it.
If the projector is not supplied with power, check the power
cord for connection and turn on the power. To connect the
cord and turn on the power correctly, see page 35 "Turning
On the Projector".
2 Check to see whether the
projector is in Interactive
Mode.
If Interactive Mode is set to [Off], switch it to [On]. For
details about how to check whether the projector is in
Interactive Mode, as well as how to specify the mode, see
page 84 "Enabling Interactive Mode".
3 Check to see whether the
computer USB adapter is
connected to in the
computer.
If the computer USB connector is not connected, connect it
to one of the USB ports on the computer.
4 Check to see whether the
computer USB adapter
inserted in the computer is
registered to the projector.
When registered, the computer USB adapter flickers once
every 0.5 seconds. Then, when the projector and the
computer USB adapter are recognized, the adapter flickers
once every two seconds.
If the adapter flickers twice every 0.5 seconds, the projector
needs registering. To register it correctly, see page 85
"Registering the Computer USB Adapter".
5 Check that the computer is
connected to the projector
using RGB cables or an
HDMI cable.
The interactive function becomes inoperable if anything
other than RGB cables or an HDMI cable is used.
To connect these correctly, see the page 30 "Connecting to
the RGB out port" or page 30 "Connecting to the HDMI
port".
6 Check that the computer
screen is projected on the
projector screen.
The electronic pen is not recognized unless the computer
screen is projected. To project the screen correctly, see
page 36 "Projecting an Image".
7 Check to see whether the
power switch of the
electronic pen is set to "On".
If the power switch of the electronic pen is set to "Off", turn it
to "On". For details about the location of the power switch of
the electronic pen, see page 93 "Electronic Pen Parts and
Their Functions".
