Normal Average value
This method displays a running average of the wind speed over
the selected period. Each second, the oldest wind speed value
is deleted and the average is recalculated with the most recent
wind speed reading.

Peak Average value
This method displays and maintains the maximum average
wind speed value with no time limit. The peak average value
display is reset by pressing the RES key for 4 seconds.

Setting wind chill calculation method
With the WWP in the Wind Chill screen (propeller icon shown in the top of the display and the
snowflake icon shown in the left of the display) press the SUB key for 4 seconds and select the
wind chill calculation method. In 2000 the formula for calculating wind chill was changed; use
the ▼ or ▲ key and select the OLD or NEW formula. The graph below shows the difference
between the two calculation methods. More detailed information on the two calculation methods
can be found on meteorological websites.
