Hull Unit Configuration page
A hull unit may be provided as an option. It allows you to lower and hoist the transducer. If a hull unit is used, you must use the options on the Hull Unit Configuration page to specify this. You can enable or disable the use of a hull unit. Once enabled you can choose which hull unit to use.

Description
If a hull unit is used, select Hull Unit Enabled to allow the SN90 system to use it. Select which type of hull unit that has been installed. You only need to do this once.
If you do not have a hull unit on your SN90 system, make sure that the hull unit is disabled on the Hull Unit Configuration page.
Note
The choices you make are vital for all operation. Accidental changes to the settings may cause damage to your SN90 system.
If a hull unit is used, but disabled on this page, the transducer is not protected against accidental transmissions.
If a hull unit is used, it must always be enabled. If you disable the hull unit, all hull unit functionality will be removed from the SN90 system.
•  All information in the SN90 user interface is inaccurate or wrong.
•  The Hull Unit button disappears from the top bar.
•  The system protection that is automatically activated when the transducer is retracted is disabled.
