Troubleshooting - ADVANSEA DEPTH S400 Manuel Utilisateur

4. Troubleshooting

This troubleshooting guide assumes that you have read and understood this manual.
It is possible in many cases to solve difficulties without the need for the after-sales
service. Please read this chapter carefully before contacting your AdvanSea retailer.
1. The unit will not power on:
2. Wrong or incoherent depth reading:
It is recommended to do a test with another working sensor (hold it under
water near the boat) to check if the sounder and the on-board sensor are
working correctly.
3. SIMU flashing on the screen, with incoherent readings displayed.
If the problems continue, we recommend you contact your advanSea retailer or our
customer support department. All contacts can be found at www.advansea.com.

with too thick a coat of paint.
