6-5 Cleaning and maintenance

To avoid damage, clean the screen only with a
damp cloth and mild detergent when dirty or
covered in sea salt. Avoid abrasive cleaners, petrol
or other solvents.
Cover or remove a transom-mounted transducer
when repainting the hull. If painting over a
through hull transducer with antifouling paint,
use only one coat of paint. Remove the previous
coat of antifouling paint by sanding it lightly.

To optimize performance, avoid walking on
or jamming cables and connectors. Keep the
transducer free of weed, paint and debris. Do not
use a high pressure water blast on a speed sensor
paddlewheel as it may damage the bearings.
When not in use, the Explorer 443d/443df can
be removed from the installation bracket and
stored in the Northstar carry bag, or left on the
installation bracket and securely covered with the
sun cover supplied.
