3. Press the set key to start the countdown. Audible beeps will count you
down to the start.
4. If the initial gun was not timed accurately, press the set key at any
subsequent gun to automatically resynchronise the timer to the nearest
full minute.
5. When the countdown reaches zero, Micro Compass returns to the mode
it was in, before the countdown timer was set.
For rolling starts, count the number of fleets ahead of your start, and
multiply the start time accordingly. This procedure ensures you have
an automatic transition to the main page at the start.
Establishing the wind patterns
To establish the wind patterns, you will need to arrive in the starting area
early and spend time sailing up the first beat. During this time, the Micro
Compass should be in Tactical mode and you should:
Check the tack angle is correct for the conditions. If you find the wind
direction reads higher on starboard tack than on port tack, you should
reduce the tack angle and visa versa. To change the tack angle, press the
set key once, then use the set or mode key to adjust the flashing "tack
angle" up or down. After 5 seconds, the screen will automatically revert to
Tactical mode.
Watch the wind direction for some time, to establish its average value
and the size and frequency of changes.
Changing the resolution of the tactics scale
Trials have shown that the optimum resolution for the tactics display is 5˚.
This allows sufficient resolution to detect meaningful wind shifts, but
eliminates the distraction of small errors in the tack angle.
The adjustment range is 1˚, 2˚, 5˚or 10˚. To change the resolution, press
AND HOLD the set key for 2 seconds, then use the set or mode key to adjust
the flashing "resolution" up or down. After 5 seconds, the screen will
automatically revert to Tactical mode.
