Maintenance items
Item Check point
Connectors
Check that all connectors on the rear panel of the transponder
unit are firmly connected.
Cabling Check cabling for damage. Replace if damaged.
Ground terminal Check the ground terminal for rust. Clean if necessary.
Ground wire Confirm that the ground wire is firmly fastened.
Transponder unit
cleaning
Dirt and dust should be removed from the transponder unit
with a soft, dry cloth. Wipe the LCD carefully to prevent
scratching, using tissue paper and an LCD cleaner. To remove
dirt or salt deposits, use an LCD cleaner, wiping slowly with
tissue paper so as to dissolve the dirt or salt. Change paper
frequently so the salt or dirt will not scratch the LCD. Do not
use solvents such as thinner, acetone or benzene for cleaning;
they can remove paint and marks and deform the equipment.
