Blink Codes
After the sonar module is installed, it turns on when the
chartplotter is turned on. The color status LED on the sonar
module indicates its operational status.

Blinking
The sonar module is connected to a
chartplotter and is operating properly.
You should see sonar data on the
chartplotter.

The sonar module is turned on, but is
not connected to a chartplotter, or is
waiting to connect to a chartplotter. If the
sonar module is connected to the
chartplotter and this code persists,
check the wiring connections.

Cored Fiberglass Boat Hull Installation
Instructions
Installing a Thru-Hull Transducer with a Fairing Block
Drilling the Transducer Stem Hole and the Anti-Rotation
Bolt Hole in a Cored Fiberglass Hull
Before you can drill the hole for the anti-rotation bolt, you must
drill the hole for the transducer stem (
Stem Hole and the Anti-Rotation Bolt Hole in a Cored Fiberglass
) and you must cut the fairing block (
).
The core must be cut and sealed carefully to protect against
water seepage.
1
Select a mounting location without surface irregularities or
obstructions.
2
Using the template, mark the location of the stem hole and
anti-rotation bolt.
3
Drill a 3 mm (
1
/
8
in.) pilot hole through the template and hull
at the stem hole location.
The hole must be perpendicular to the water surface.
4
Place masking tape over the pilot hole and surrounding area
outside the hull to prevent damage to the fiberglass.
5
Using a 32 mm (1
1
/
4
in.) bit at the stem hole location, drill
from outside the hull through the outer skin , inner skin ,
and the core .
The hole must be perpendicular to the water surface.
6
Sand and clean the inner skin, core, and outer skin around
the hole.
7
Seal the exposed inner core with epoxy , and allow the
epoxy to set thoroughly.
8
While holding a drill with a 9 mm (
3
/
8
in.) bit plumb, drill the
anti-rotation bolt hole through the hull from outside the hull.
The hole must be perpendicular to the water surface.
9
Sand and clean the area around the hole with a solvent wash
to remove dust particles.
Applying Marine Sealant to a Thru-Hull Transducer
You must apply marine sealant to the transducer to ensure a
tight, waterproof seal between the fairing block and the hull. Do
not apply sealant directly to the stem or anti-rotation bolt.
Apply marine sealant around the base of the stem and
anti-rotation bolt on the transducer.
Installing the Transducer with a Fairing Block
It is recommended that two installers complete these
instructions, with one positioned outside the boat and one inside
the boat.
NOTE:
When installing the transducer in a cored fiberglass hull,
avoid over-tightening the nuts to prevent damaging the hull.
1
Apply marine sealant at the base of the anti-rotation bolt
and transducer stem .
