Important Safety Information

 WARNING

Failure to follow these warnings, cautions, and notices could result in personal injury, damage to the vessel or 
device, or poor product performance.
See the Important Safety and Product Information guide in the product box for product warnings and other 
important information.
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or 
product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product 
specifications. In addition, connecting the power cable without the appropriate fuse in place voids the product 
warranty.

 CAUTION

To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, 
cutting, or sanding.
To avoid possible personal injury or damage to the device and vessel, disconnect the vessel's power supply 
before beginning to install the device.
To avoid possible personal injury or damage to the device or vessel, before applying power to the device, make 
sure that it has been properly grounded, following the instructions in the guide.
To avoid possible personal injury or damage to this device and vessel, only install this device when the vessel is 
on land, or when properly secured and docked in calm water conditions.

NOTICE

For the best possible performance, the device must be installed according to these instructions.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

Read all installation instructions before proceeding with the installation. If you experience difficulty during the
