Setting the Barometer altitude
A long press (4 seconds) of the MENU key gives access to the
Barometer set-mode and will cause the barometer reference
altitude to blink. Use the
S and T keys to set the altitude for
your current location. This setting is necessary to obtain a
precise QNH indication (see barometer general information
above).

Setting the time units for the pressure trend graph
A long press of the SUB key allows the time period represented
by each bar on the pressure trend graph to be set. Use the
S
or T keys to scroll through the values of 15 minutes, 30
minutes, 1 hour or 2 hours per bar. The WWP maintains the
barometric pressure values for the past 24 hours regardless of
the time period set for the graph. This means that you can
reduce the time period at any time to show greater detail, or
increase it to show the longer term trend.

Note: When you select a screen containing a trend graph, the
display will show the graph interval for 2 seconds before the
graph appears, to remind you of the time period per bar of the
graph (1 hour 0 minutes per bar in the example above).
