Condensation under sounder screen

[Anonymous]

I have a Furuno LCD Sounder, model FCV-582L imbeded on my boat.
When I uncovered my boat this spring I had some condensation under the sounder screen.
Any suggestions on what to do about it ??
Thanks

It would be best to have your local dealer evaluate the unit. Due to the age of this unit, your seals might be breaking down due to heat/sun and might need replacement. Afterwards they can normally add a desiccant package inside the case to dry out any moisture and prevent condensation.
