Description
You can lessen error in the altitude readings displayed by the watch by
manually inputting accurate local altitude and elevation values. You can find
out the elevation at your current location from signs, maps, on the Internet,
etc. While mountain climbing, it is highly recommended that you make a habit
of regularly comparing altitude readings produced by the watch with locally
available elevation indications, and of performing this procedure as required.
