Maintenance of the VDO Depth Sounder
The indicating unit is maintenance-free. Use a humid, lint-free or antista-
tic cloth for cleaning. Do not use cleaning detergents.
At regular intervals (twice per season) check the two O-rings of the echo

mages. Even signs of the slightest wear require O-ring replacement.
