Maintenance
Testing the Installation
NOTICE
You should check your boat for leaks before you leave it in the
water for an extended period of time.
The transducer must be in the water to work properly.
1
When your boat is in the water, check for leaks near the
transducer installation site.
2
If leaks are found, apply marine sealant around the
installation site, let the sealant cure, and repeat step 1.
Cleaning the Transducer
Aquatic fouling accumulates quickly and can reduce your
device's performance.
1
Remove the fouling with a soft cloth and mild detergent.
2
If the fouling is severe, use a scouring pad or putty knife to
remove growth.
3
Wipe the device dry.
