Module No. 3554

You can use the procedure below to display the differential between a reference altitude and another altitude. This makes it easy to measure the altitude differential between two points while climbing or trekking.

1. Use the contour lines on your map to determine the altitude differential between your current location and your destination.

2. Take an altitude reading of your current location.

Checking the Current Altitude

3. Hold down (A) for at least two seconds.

This displays the altitude measurement setting screen.



4. Use (A) and (D) to move the pointer to [DIFF RESET].

5. Use (C) to set your current location’s altitude as the reference altitude.

After the setting operation is complete, a check mark appears for a few seconds, and then the altitude measurement setting screen re-appears.

6. Press (E).

This returns to the altitude measurement screen.

7. While comparing the difference between the altitude you found on the map and the altitude differential displayed by the watch, advance towards your destination.



When the altitude differential you found on the map is the same as that displayed by the watch, it means you are close to your destination.
