(2) Check for evidence of any corrosion of the scanner unit, display unit, or
its cable and connectors. Clean as required.
(3) Check that the cable connector is secure.
5.2 CLEANING THE SCANNER UNIT
Wash the exterior of the scanner unit with fresh water. But do not immerse the
unit. A heavy deposit of dirt or caked salt on the surface of the scanner may
cause a considerable drop in the radar performance. Clean the face of the dis-
play unit with a clean, soft, lint-free cloth slightly dampened with fresh water.
5.3 CLEANING THE DISPLAY SCREEN
Dust on the screen tube will reduce the grass transparency and make the video
image dim. Wipe the screen surface with a soft lint-free cloth (made of flannel
or cotton). A cloth moistened with an antistatic agent will not cause a problem.
When using it, wipe softly; never rub the screen surface with excessive force.
