8. Fasten the chains, cables, or lines as far fore and aft as is
practical. Use sufficient tension to support the pipe when the
boat is underway.
9. Route the cable to the instrument being careful not to tear the
cable jacket. To reduce electrical interference, separate the
transducer cable from other electrical wiring. Coil any excess
cable and secure it in place with cable ties to prevent damage.
10.Refer to the survey recorder owner’s manual to connect the
transducer to the instrument.
Maintenance & Replacement
Anti-fouling Paint
Surfaces exposed to salt water must be coated with anti-fouling
paint. Use water-based anti-fouling paint only. Never use ketone-
based paint since ketones can attack many types of plastic
possibly damaging the transducer.
Inspecting the Cable
Periodically inspect connections and connectors for indications of
corrosion. Inspect the cable for kinks, abrasions, and cuts. Repair
any damage using Airmar’s splash-proof Junction Box No. 33-035.
Cleaning
Keep the transducer assembly free of weeds and debris.
Aquatic growth can accumulate rapidly on the transducer’s
surface reducing its performance within weeks. Clean it using a
Scotch-Brite® scour pad and mild household detergent, being
careful to avoid making scratches. In severe cases, lightly wet
sand the surface with fine grade wet/dry paper.
Parts & Transducer Replacement
The information needed to order a replacement transducer is
printed on the cable tag. Do not remove this tag. When ordering,
specify the part number, date, and frequency in kHz. For
convenient reference, record this information on the top of page 1.
Lost, broken, or worn parts should be replaced immediately.
Obtain parts from your instrument manufacturer or marine dealer.
