INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
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 personal
injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in
the product specifications. 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.
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.
You must use the cables and connectors provided by Garmin
when installing the system. Using any cables or
®
connectors other than those supplied by Garmin will void your warranty.
You must not cut, terminate, or splice the coaxial cable. Modifying the coaxial cable may cause the system to
malfunction. Failures caused by an extended coaxial cable are not covered under warranty.
The camera comes with mounting screws, but they may not be appropriate for your hull material. You must use
the appropriate screws for your hull material to avoid damaging the hull.
You must tighten the SMA connectors on the cameras and the GVAM 10 black box to the specified torque
measurement in these instructions. Failures caused by improperly tightened connectors are not covered under
warranty.
Read all installation instructions before proceeding with the installation. If you experience difficulty during the
installation, contact Garmin Support.
