■ If your presentation includes computer audio, make sure the
volume control on your computer is not turned all the way down
or muted. In Windows, you may be able to check this by clicking
the volume control in your Windows system tray (lower right
corner of the screen). On a Mac, you may be able to adjust the
volume from your menu bar (top right corner of the screen) or via
the volume control function keys.
■ If you’re using a DVD player or other video source, make sure the
cables are connected correctly, as described on page 32.
■ 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’s
Audio port (beneath the
Computer2 port) when the computer’s video cable is connected
to the
Computer1, Computer2, or BNC ports.
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 or
BNC input ports. See page 31.
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 116.
■ Set Standby Mode to Network 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.
