No Images on TV monitor

· 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 power 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.

Out of focus

· The object is too close to the lens. Check if it does not stand higher than

15cm (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 intensity of illumination is not sufficient. Press the upper button

[UPPER] on the front panel or the lamp button [LAMP] on the wireless

remote control and turn ON the upper lamp.

· The AUTO iris level is on the "CLOSE" side. Press the open button

[OPEN] on the operation panel or the iris open button [IRIS OPEN] on

the wireless remote control.

Input selection can not be made.

· Inputting to S-video while connecting output of C-video to the monitor

or vice versa. (Refer to the "Table of Video -and Audio-in/out Terminal

Selections" on P.20.)

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.

When <SHUTTER> is changed to <FL> and <50Hz> is selected in the

OSD menu, the image flickering may be mitigated. (Refer to P.29.)

Replacement of fluorescent lamp

The lighting lamps (fluorescent lamps) are expendables. When any of them begins to shimmer or be less bright, replace

it.

Note: For the replacement of the lamp, consult your dealer from whom you have purchased your Visual Presenter or

an authorized ELMO service center.
