3. User Maintenance
Transducer Maintenance
The transducers are virtually maintenance free, but occasional cleaning may be necessary to remove
growth/shell (The acoustic signal may be decreased if extensive shell grow on sensor)
Operator Unit and Transceiver Unit Maintenance
The operator and transceiver unit contains no user serviceable parts, and requires no maintenance apart
from occasional cleaning of the front panel. Please use a soft cloth and no chemicals except cleaning
alcohol.
Note: Dry docking the vessel. The transducer will only tolerate short periods in air. When the vessel is
placed in dock, or the transducer is lifted, the power must be shut o at the switch or circuit breaker.
The softkey SYSTEM o only places the system is standby, and power glitches may activate the
system.
