■ If you’re using a computer audio cable, make sure it is connected
to your computer’s headphone jack or audio out jack.
Connect the other end to the projector as described on page 46.

equipment to PCM output.
■ If your equipment is connected through the LAN port, or the
HDMI port with the PowerLite G5550NL/G5650WNL/
G5950NL, make sure you’ve set the
Audio Input setting
correctly. See page page 119.
Nothing Appears on an External Monitor
■ The only images that can be displayed on an external monitor are
computer images connected through the
Computer1,
Computer2 (G5550NL/G5650WNL/G5950NL only) or BNC
input ports. See page 45.
■ If you are using the Split Screen function, the computer image
must be on the left side if you want to display it on an external
monitor. See page 62.
Solving Network Problems
The projector does not send e-mail alerts even though the
e-mail notification function has been turned on.
■ Make sure the mail notification function is set correctly in the
configuration menu. See page 98.
■ Set Standby Mode to Communication On in the Extended
menu. Otherwise, the projector cannot send e-mails when it is in
Standby mode (when the power is off).
■ If a critical problem develops with a projector which causes it to
suddenly stop working, it may not be possible for the projector to
send a message.
