10. TROUBLESHOOTING HINTS

Symptom	Possible cause/countermeasure
No image on the screen	• Cable is not properly connected to the video-in terminal of
	monitor.
	• The power cord is disconnected from the wall AC outlet.
	• The plug is disconnected from the power cord receptacle of the
	Presenter.
	• The power switch is not turned ON.
	• Zoom is set at TELE to display only white/black part of the
	material.
	• The switch is turned ON immediately after it is turned OFF. In
	this case, the Presenter may not start. Wait several seconds after
	turning OFF the power switch, and then turn ON the power
	switch.
	• The In/Out selector switch is not correctly selected according to
	connected equipment (See P. 8 and 13).
Out of focus	• The object is too close to the lens. Check if it does not stand
	higher than 15 cm (5.9 in.) above the stage surface.
	• Zoom is set at TELE after focusing at WIDE angle.
	Focus on the point of max. TELE.
	• In the auto focus, focusing is difficult in some cases.
The lamp is not quickly turned ON.	• For protection purposes, the lamp is turned ON after preheating
	for 2 seconds. This is not a fault.
Image is too dark.	• The ambient light is not sufficient. Press the lighting unit button
	[LAMP] to turn ON the upper lamp.
The image of printed matter is striped.	• This is caused by the interference between the dots of printed
	matter and the scanning line.
The image flickers	• The light from the discharge tube (50Hz) does not come to the
	screen. This may be reduced by setting the [C] key of the In/Out
	selector switch to [1] (50Hz) (See P. 8).

If the trouble still remains after checking the above, consult your dealer or an authorized ELMO service center.
