no owners manual? Sounds like your shallow warning alarm is set.

no paper on depth finder. shallow alarm is going off, not sure how to set it. It was going wild in 100' of water. thanks Jeff

Mine never worked good. Transducer is epoxied into bildge. I read some where that you will never get a good working one due to the hull composites on Fountain unless you drill into the hull and thru-it. I have a Lowrance and sent the brain box to them, ck'd out fine so I bought another transducer and that did the same thing.

They default to 10 ft when powered up. Push and hold the little button in the center to adjust the depth setting and/or to turn on/off the alarm.

You should be able to hit alarm button to disable/turn off. Call Livorsi if no one else chimes in here.

yea mine does the same thing, and will not read when moveing more than 10 mph. it will read 100ft when only 3ft. and so on
