As with all advanced instruments, there are a few important
matters about the SX90 that you must remember.
Before you switch on the sonar
When you power up the sonar, the transducer is lowered down
below the vessel's hull. Make sure that you have sufficient water
depth before you do this!
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.
If something breaks down
If you think that something has been damaged on the sonar,
contact your local dealer for advice.
