How to install the stays (anti-vibration measure)
Install stays from the top of the hull unit to the ship's hull. The stays should be angle
iron with a size of 75×75×9 mm or more and at least two pieces should be used; one
each to ship's bow and stern directions. This measure must be done to prevent
damage to the transducer.
Do not install the stays on a crossbeam on the overhead. Vibration-resistance effect
is reduced since vibration is applied to the stays as rotation force. Install them horizon-
tally.
