6 TROUBLESHOOTING

6.1 Easy Troubleshooting

This paragraph describes how to cure operational problems, which can be made by observing the
radar picture and using operator controls and keys without opening the display unit, antenna unit or
other equipment units.

Problem Remedy

Power turned on but radar does
not operate at all.

Control panel is not illuminated.

Check fuse. If it is blown, replace it.

Marks, legends and noise appear
but no echo.

Check Tx fuse. If it is blown, replace it.

Picture not updated or picture
freeze up.

•

Check connection of signal cables.

•

For video freeze up turn off and on the radar

TUNE control adjusted but poor
sensitivity.

•

Clean the radiator surface.

•

Remove water from the feeder line.

•

Second trace rejection is on. Turn it off. (See paragraph 1.31.)

Range changed but radar picture
does not change.

•

Try to hit the [+] and [-] keys several times.

•

Turn off and on the radar.

Only 2 parallel index lines when 6
lines are wanted.

Set index line interval correctly on the OTHER menu.

Poor discrimination in range.

Adjust A/C SEA control.

True motion presentation not
working properly.

Try to press MODE key a little harder.

Target not tracked correctly.

Adjust A/C SEA and A/C RAIN controls.

Range rings are not displayed.

Adjust brilliance of range rings on BRILL menu.

No own ship marker

On R-type check setting of OS MRK on OTHER menu.
