Cable Routing Grommets
When routing cables through your boat, it may be necessary to
drill holes to route the cables. Cable routing grommets can be
used to cover cable installation holes. The grommets do not
create a waterproof seal. If necessary, apply a marine sealant
after installation to weatherproof around the grommet and the
cable. You can purchase grommets from your Garmin dealer or
directly from Garmin at www.garmin.com.
Blink Codes
After the sounder is installed, it turns on when the chartplotter is
turned on. The two-color (green and red) status LED on the
sounder indicates its operational status.
