17.4 Servicing
Caution
When handling the transducer housing be careful not to
touch any of its internal components as they are
extremely sensitive and are easily damaged.
The transducer is assembled and adjusted at manufacture to precision
tolerances and must not be further disassembled. If any part of the transducer
is unfit for further service, the complete transducer assembly must be changed.
