9.10.2 Scanner unit
WARNING
When performing maintenance or inspection of the scanner unit, be sure to
shut off the safety switch of the scanner unit after turning off the power of the
display unit. Failure to do this may cause severe electric shock or
breakdown or the sudden movement of the scanner unit may cause bodily
injury or breakdown.
CAUTION
Since the magnetron in the modulator circuit emits strong magnetism, watches
or magnetic cards should not be brought into close proximity of the modulator
circuit. Doing so may cause breakdown and destruction of data contained in
such items.

(a) A radiation surface of radiation unit (JMA-2343: Whole surface of the radome cover /
JMA-2344: Front side of radiation unit) contaminated by smoke, dust, or paint would
cause attenuation or reflections of radio waves, resulting in reduced radar performance.
Periodically check the radome scanner unit. If it proves dirty, wipe the radome surface
with a soft lint-free cloth moistened with alcohol or damped cloth.
CAUTION
Never use such solvent as Thinner, Gasoline, Benzen, Trichlene or Kentene
for cleaning. Those solvents deteriorate the surface.
