IMPORTANT
•
This unit employs a semiconductor pressure sensor
that could be affected by temperature change. While
taking the altitude measurement, ensure that the unit
is not exposed to sudden temperature changes.
•
It is recommended to calibrate the altitude or sea level
pressure regularly to maintain the accuracy of the
watch. To re-calibrate the watch you simply set the
current altitude or sea level. (See “Set the Altitude” or
“Sea Level” section.)
ALTITUDE BAR CHART
The altitude bar chart at the bottom of the display shows
the altitude history. It consists of 7 rows and 14 columns.
The latest reading is entered in the right hand column and
always at the height of the 4th row. Therefore, all the other
readings will adjust their position to reflect the latest reading.
Latest Reading
NOTE
1 row = 20m (20m = 65.6ft)
1 column = 1 min
Look at your watch to see what your current altitude
level is, then look at the bar chart to see the changes in
altitude. See the table below for how to read the bar
chart in more detail.
