General Maintenance
Periodically remove the inner transponder assembly to reveal the anodised aluminium
pressure housing. Check for any signs of corrosion due to damage or pitting of the
anodising. If corroded replace or clean with wire brush, de-grease and paint to protect area.
Ensure that the transducer is visibly undamaged. Any significant damage to the polyurethane
coating can cause a leakage path to the piezo electric ceramic causing acoustics failure of
the transducer. Any leakage of water can also possibly enter the inner pressure housing
through the transducer.
Ensure that the transducer within the outer housing is free from mud, stones and importantly
grease. These can all significantly degrade the acoustic performance. If the transducer is
contaminated with grease clean and wash with a mild detergent.
Always wash down the unit with fresh water after use and prior to storage, thoroughly dry the
all parts and store in cool dry conditions. This will minimise any long term corrosion
problems.
To maximise battery life in storage, battery packs can be disconnected prior to long periods in
storage. Store in cool, dry environment - high storage temperatures significantly increase the
batteries self drain characteristics and therefore remaining life.
