SAFETY INSTRUCTIONS
WARNINGWARNING
Do not use the WIND mode under strong
or unstable wind.
The boat may capsize.
When gybing, watch for moving boom.
The boom may strike a person, possibly
causing serious injury.
FOREWORD
CAUTION
Trim the sail to the wind always optimally.
Wrong sail position may cause the autopilot's
control error.
Monitor the wind direction when using the
NAV mode.
The wind direction on the display may change
because the heading moves according to
route.
Try the TACK mode in good wheather to
confirm how it works.
Feature
The wind m ode is designed specially for use on sailboats t o k eep the direction

AWA: The direction (in relation to shi p’s bow ) of the wi nd as it appears to that on
board, detec ted by the wind sensor. AWA mode requires wind angle and speed
data. Use this mode when wind i s stable.
TWA: The actual wi nd direction; combination of the AWS (Apparent Wind Speed)
and own boat’s speed. This m ode r equires apparent w ind angle, apparent wind
speed, ow n boat’s speed and ow n boat’s heading. Use this mode when there is
a downwi nd uns table.
