depth sounder help

[sluggo]

I picked up my 2006 3600 Sovran on Saturday, and brought it back to its 'home' port.  I noticed the depth sounder was just showing dashes (- - -).  It worked fine last year.  Any thoughts??  I haven't looked yet, but is it a thru hull transducer?  Could there be 'slime' on it and needs cleaned off?? (I am in fresh water)  Or is something else amiss??TIA

Assuming you have RayMarine electronics, common to Tiara's of that time period, try this: go to the Sounder Page, select MENU, select Fish Finder Setup, select DSM Settings, select DSM Reset.

This will "ping" your transponder and may correct the problem. This is an issue not entirely uncommon to the RayMarine electronics, and you may have to "reset" in this manner from time to time.

Hope this helps.

Yes I have a ray marine e-120. I can't find the sounder page. I looked in the menu and did not see it   I looked at page and did not see it. The depth sounder days ray marine ST40.  So how do I get to the sounder page??? Tia
