MAINTENANCE & TROUBLESHOOTING
Preventive Maintenance
Regular checks
•
Regular maintenance is important for continued
performance. Check the following on a monthly basis.
•
Check that all connectors and cables are securely
tightened.
•
Check grounding systems of units for corrosion.
•
Also regularly measure voltage to confirm that it is within
prescribed rating.
Cleaning of units
Display unit/ transceiver unit
Accumulated dirt can be wiped off with a soft cloth. If necessary,
a mild detergent diluted in water may be used. Chemical
cleaners should not be used to clean any unit; they can remove
paint and markings.
Transducer unit
Barnacles and other marine life adhering to the transducer face
can cause a considerable drop in performance. Check the
transducer face regularly for marine life and clean if necessary.
The transducer should never be painted.
