Action
The Wind Angle
displays are
incorrect.
The wind transducer
is not connected to
the IS15 Transceiver
properly.
Check the wind transducer’s connections
to the IS15 Transceiver and to the Junction
Box.
Check that the wind transducer cable is
not damaged.
Contact your dealer.
The Wind Angle has
always been
incorrect.
The wind transducer

Calibrate the wind transducer. (Using
another instrument.)
Make checks as for ‘the wind angle

A broken vane can only be replaced by the factory, as the Masthead Unit (MHU)
needs new calibration.
