Trouble shooting guide
Symptom Action
No image appears on the monitor at power
on, or the picture is distorted or continually
scrolling.
• Verify that the video cable is correctly connect­
ed to the system and to the monitor.
• Verify that the monitor is set to the correct TV
system (PAL/NTSC).
• Check the status indicator LED on the JCU.
The LED should give a flashing light during
start up and a steady light when the system is
operational. If not, check the power cable and
the mains cable to the power supply.
The system does not start in cold environ­
ment.
Depending on the ambient temperature, it will
take up to 30 minutes for the heaters to warm the
system up in extreme cold. When the heaters are
on, the system heater indicator on the JCU is lit.
The system starts normally and the system
information is displayed, but no IR image
appears.
The image could be totally out of focus. Perform
an auto focus adjustment.
The system starts up properly and gives an
acceptable image, but the system does not
react on commands from the JCU.
Check the cable that connecs the system to the
JCU.
No system information is displayed. • The Declutter feature may be active. Press the
ENTER button to display the system informa­
tion.
• Verify the settings in the Setup – Symbology
dialog box.
The IR image is totally black or white. Change the adjustment mode setting.
The IR image is of bad quality. Perform a NUC.
The autoscan points can not be changed. Ensure that IR is selected; the features for pro­
gramming of autoscan points are only available
when IR is selected.
Expected features are not displayed. The displayed menu options and features are
somewhat different, depending on if IR or TV is
selected. Ensure that correct channel (IR or TV)
is selected.
