11 Maintenance
11.1 General
IMPORTANT! Care must be taken not to use heavy water jets directly
onto microphone unit VSS-MU when vessel and/or unit is due to a
cleaning. Nor should chemicals be used. This may damage sealings
and/or water protective fabric.
It is recommended to periodically check the system. The system has a
self-test function but it will not check whether the microphone itself is
working properly. To check this, use a horn or similar device that sends
out harmonic signals with higher SPL than the background noise to
activate each microphone to see whether it is detected on the diodes
and monitored in the internal loudspeaker of the master unit. It is also
recommended to visually check all terminal cables and microphone
housing for damages.
Check the microphone unit every 3 months.
11.2 Spare Parts
The microphone housing consists of four microphones and a
preamplifier. The housing is regarded as one spare part. It is designed
to be easily changeable.
