【CAUTION】 T his watch is not a special measuring instrument, therefore, use
the measuring function as a guide.
When using the direction indicator for full-fl edged mountaineering,
make sure to bring a backup compass.
【CAUTION】 F or correct measurement, correct the altitude and direction before
measuring. → "How to correct altitude" Page 151, "How to correct
