As with all advanced instruments, there are a few important
matters about the SH90 that you must remember.
Before you switch on the sonar
Before you power up the sonar, make sure that you have sufficient
water depth to lower the transducer!
When the sonar is not in use
To protect the sonar when it is not in use, we strongly advice you
to hoist the transducer, even though you may not switch off the
power. In narrow or shallow waters this is very important, since
you may - in worst case - run the transducer into the bottom.
This will damage the transducer and the transducer shaft, and
extensive repair is required.
When you dock the vessel
It is very important that the sonar system remains switched off
when the vessel is in dry dock. If the transducer is subjected
to transmit power when it is in open air, it will be damaged.
As a safeguarding measure, you can remove the power fuses
on the sonar system before the vessel is docked. As an extra
safeguarding measure, the sonar is by default powered up with
the transmit power switched off.
Manual operation of the hull unit
In the event of improper operation, the powerful 3 kW electric
motor may cause serious damage to the equipment and/or injury
to personnel.
Therefore, before you start the operation, read carefully through
the relevant procedure(s). You will then familiarize yourself
with the method .
