Important Safety Information
WARNING
See the
Important Safety and Product Information
guide in the chartplotter, fishfinder, or sounder product box for
product warnings and other important information.
You are responsible for the safe and prudent operation of your vessel. Sonar is a tool that enhances your
awareness of the water beneath your boat. It does not relieve you of the responsibility of observing the water
around your boat as you navigate.
CAUTION
For the best possible performance and to avoid potential injury, damage to the device, or damage to your vessel,
installation by a qualified marine installer is recommended.
Failure to install and maintain this equipment in accordance with these instructions could result in damage or
injury.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
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
installation, contact Garmin
®
Product Support.
To prevent interference and avoid possible overheating damage, do not install the transducer near the engine or
in the engine room.
To prevent damage to the cable and the transducer, do not use the cable to pick up or pull the transducer.
Always operate the transducer when it is submerged. Operating the transducer when it is exposed to the air may
result in damage due to overheating.
To prevent permanent damage to the surface of the transducer, do not use solvents such as mineral spirits,
acetone, Methyl Ethyl Ketone (MEK), or similar products when cleaning. Do not use a power sander or pressure
washer to clean the transducer.
