Phone and ask them if you can send it in. Very often your local marine electronics shop will have a preferred technician.

Wrong, if it was set-up properly it would not lose depth. Dealer is F.O.S., ... or incompetent!!

Think of where the transducer is fitted on your boat . As turbulence is the only problem you need to worry about. It needs too be on the transom but in between the lower 2 chines

Hello! Do you have the PDF users guide for your unit? I'm looking at a copy in the troubleshooting section...I don't want to cover information you have already looked at or tried...Since I do not know if you have that manual I'll give you a few items to check...

Measure the battery at the units power connector...Must be at least 11 volts DC...In portable mode it uses 8 D cell batteries= 12 volts
Make certain the Transducer is securely connected...
Did you use the in-line fuse supplied with the unit?...
Try the Manual Depth Range...First turn off Auto Depth Range...From the sonar Page Hit MENU...Down-arrow to Auto Depth Range...Hit ENT...Hit Up-Arrow to Depth Range...Hit ENT..
And the Depth Scale Range appears...Up-Arrow or Down-Arrow to select a different depth range...Hit Exit...The minimum depth the unit can read is 5 feet...

If you do not have the PDF guide, here is the link...

Yes... or it is unplugged... or the wire is broken...

Typically you hear a clicking sound at the transducer when it is powered and running but in your case all function is missing from the display and temp and depth is off of the transducer..

Try good alakaline batterys(duracell or energizer)alot of those rechargables dont hold amperage and dont stay recharged long!!!! :)
