After the accumulated data is displayed, the watch will then display either of the following views of the altitude data:
•Current time, altitude and temperature data.
•A graph of the altitude changes for the last five hours (each column represents 10 minutes) shown in the center of the display. The current time is displayed in
the upper line and the current altitude is displayed in the lower line.
Press and release the START/SPLIT button to switch between these two views.
Selecting Altitude Units
While viewing the current time, altitude and temperature data, press STOP/RESET to switch units between feet (FT) and meters (M).
Altimeter Performance
When ALTI mode is first entered, the watch will update the altitude information every two seconds and will continue this fast data update rate for thirty minutes. After thirty minutes elapses, if the watch determines that the altitude is no longer changing significantly, it will reduce its data update rate to that of the barometer function (every 2.5 minutes). At that point, two things will happen:
1.The weather icons will appear in the upper part of the display indicating the forecast.
2.The watch will stop data accumulation for the ACC and HIGH statistics.
The watch will continue to monitor the air pressure at this slower rate and, if it determines that the altitude is chang- ing significantly, it will go back to faster update rate. If this change occurs, the weather icons will be removed from
