[DG] [DG11] i70s Calibration not responding

[Derek - Raymarine - Moderator]

Hi Lukes

Thankyou for your enquiry,

The speed adjustment will only work if the STW and the SOG are within range of each other (within 1 or 2 kts). The fact that the Add Cal point is not working may mean that the SOG is not accurate or the STW transducer is not working correctly.

Please check the paddlewheel is clean and spinning freely, if the transducer is more than a couple of years old, change the paddlewheel using a service kit to replace both the paddlewheel and the shaft.

Regards

Derek
