Check item

Check the projector to make sure that power is supplied to it.

Check to see whether the projector is in Interactive

Mode.

Solutions

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".

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".

If the computer USB connector is not connected, connect it to one of the USB ports on the computer.

Check to see whether the computer USB adapter is connected to in the computer.

Check to see whether the computer USB adapter inserted in the computer is registered to the projector.

Check that the computer is connected to the projector using RGB cables or an

HDMI cable.

Check that the computer screen is projected on the projector screen.

Check to see whether the power switch of the electronic pen is set to "On".

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".

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".

The electronic pen is not recognized unless the computer screen is projected. To project the screen correctly, see

page 36 "Projecting an Image".

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".

Check item

Check to see whether the battery of the electronic pen is out of charge.

Solutions

When the power switch on the electronic pen is turned on, the communication indicator on the electronic pen flickers. If the indicator fails to flicker, check that a rechargeable battery is installed in the electronic pen. If a rechargeable

battery is installed, recharge it. For details, see page 96

"Installing a Rechargeable Battery into the Electronic Pen"

and page 98 "Recharging the Electronic Pen".

Point the electronic pen nib toward the projected screen and check to see whether the electronic pen is recognized by the projector.

If the electronic pen is recognized correctly, the pointer on the projection screen will move in unison with the movement of the electronic pen. For details about how to make the

projector recognize the electronic pen, see page 88

"Enabling the Projector to Recognize the Electronic Pen".
