SET CURRENT ALTITUDE AND RESOLUTION
When you first use the watch, it is important to set the current
altitude and local sea-level pressure so your ascending and
descending altitude can be accurately measured.
You can
find the current altitude by comparing your position to a
topographical map
, and then entering the value in the watch.
It is necessary to reset the altitude after being in a
pressurized chamber (such as an airplane).
For instructions on setting the sea-level pressure, refer to the
next section.
Tip:
You can also set the current altitude and alarm limits with
the help of the PC software (see PC section).
(RP109 only)
The sea level pressure reading will change if the altitude
is adjusted.
• Maximum / minimum altitude alert (sounds an alarm when
exceeded)
• Maximum / ascending, maximum descending speeds
• Current vertical speed
• Rate of altitude change
The altitude is shown it two ways, as a numeric value indicating
your current altitude, and as a bar chart indicating changes in
altitude. Both values will change as you move about.
In ALTI-BARO Mode, the current altitude is always
displayed in larger font, in every screen except the sea pressure-
setting screen.

the resolution you set (next step) and the
measurement unit you selected when setting the
CLOCK (
9).
3. Press
FUNC/SET
to switch to the Resolution setting
screen, then press
ST/SP/-
