<p>PROBLEM TO BE SOLVED: To make it possible to correct an altitude without the need for a user to input a correction value during mountain climbing.SOLUTION: A CPU 101 registers correction values relating to altitudes. A RAM 110 stores the correction values registered by the CPU 101. An altitude measuring unit 108 measures an altitude. Key input means 104 selects one correction value from among the registered correction values. The CPU 101 reads the correction value selected by the key input means 104 from the RAM 110, corrects the altitude measured by the altitude measuring unit 108 on the basis of the read correction value. Furthermore, the CPU 101 displays the corrected altitude on a display 105.</p> |
