B. Continuous Altitude Measurement and Fixed Duration
Altitude Measurement
<Switching Between Altitude Display and Barometric Pressure Display>
The watch switches between the altitude display and barometric pressure dis-
play whenever button (B) is pressed during the continuous altitude measure-
ment display or fixed duration altitude measurement display.
• Altitude measuring range: -300 m to +6300 m (in 5 m units)
* “
————
” is displayed when the measuring range is exceeded.
• Barometric pressure measuring range: 452 to 1050 hPa (in 1 hPa units)
* “
————
” is displayed when the measuring range is exceeded.
* An “m” is displayed during altitude display, while “hPa” is displayed during
barometric pressure display.

Always make sure to perform altitude correction at a location where
altitude does not change. Since altitude is not measured during the
altitude correction display, if altitude changes during altitude correction,
the actual altitude and altitude displayed on the watch do not agree,
thereby preventing altitude from being measured accurately.
In addition, since the altitude and barometric pressure measurements
performed by this watch are affected by temperature, only perform alti-
tude correction after allowing the watch to acclimate to the surrounding
temperature.
<Deleting Corrected Value>
The corrected altitude is deleted by simultaneously pressing buttons (A) and
(B) for at least 2 seconds during the altitude correction display. After the cor-
rected value is deleted, approximate altitude is displayed corresponding to the
conditions of standard atmosphere. The altitude displayed at this time differs
from the actual altitude.
* When a series of hyphens “
————
” are flashing on the altitude correction dis-
play, since this may indicate that there is an abnormality in altitude measure-
ment or altitude correction, try deleting the corrected value and repeating the
altitude correction procedure.
