How to Switch between Measurement Units
!
The Watch displays altitude either in meter (m) or
feet (ft).
!
The Watch displays temperature either in degree
Celsius ( C) or degree Fahrenheit ( F).
!
To switch among different units, hold down the
[S/S] button to change the units following the
adjacent diagram.

Absolute and Relative Altitude
!
Absolute
altitude is the vertical
distance between
your current altitude and Sea Level (0 m).
!
Relative altitude is the vertical
distance between
your current altitude and the altitude of a specific
level at
which you set the altimeter to zero.
!
An example of using relative altitude:
!
The altitude difference between the starting
point and the finishing point of a trek can be
measured by Relative Altitude.
!
Set the altitude to 'Zero' at the starting point,
the Watch will show the altitude difference at the
finishing point of the trek.

Adjustment' for more details on how to set the
current altitude to zero altitude.
!
An '
r
' indicator will be shown along with the
altitude reading as long as the Altitude has been
adjusted by the 'Zero' adjustment.
!
To switch the Watch back to absolute altitude
measurement, employ one of the following altitude
adjustments: Factory Default Adjustment, Sea
Level Pressure Adjustment and Absolute Altitude
Adjustment. Check the respective chapters for
more details on how to make the adjustment.
Why the
Needs to be Adjusted
!
As the absolute altitude is calculated from air
pressure, the change of air pressure would affect
the altitude reading.
!
To achieve a more accurate result, the Watch
needs to be calibrated from time to time as
pressure may change gradually even within hours.
NOTE:
The Watch includes an automatic Sea Level
Pressure comparison device, this smart device
allows NO fluctuation of altitude readings to be
recorded when staying at the same altitude.
Altimeter
?
Altimeter Adjustment
!
There are 4 kinds of adjustment methods: Zero
Altitude, Absolute Altitude, Sea Level Pressure and
Factory Default Adjustment.
!
Zero Altitude: Adjust the altitude mandatorily to
zero for relative altitude measurement. If the
altimeter is adjusted by Zero Adjustment, an "
r
"
indicator will appear on the display.
!
Absolute Altitude: Set the altitude to a known value
and it can be recalled for a next setting.
!
Sea Level Pressure: Input a specific sea level
pressure which got from an official site.
!
Factory Default: Restore the Watch to the default
factory setting where the Sea Level Pressure is
assumed at 1013.2 mb
NOTE
: When the Ski Function is turned ON, Altimeter
Adjustment function is prohibited.
NOTE:
Altitude is calibrated independently on each
mode. For example, if the absolute altitude is
selected, the effect of the previous sea level pressure
setting will be ignored.

Functional Display
!
The Watch includes two Altimeter functional displays:
Temperature and History Display. One of the two
functional displays will appear in the top row of the
display.
!
Press the [S/S] to select between Temperature and
History Display.
Fast sampling
!
In the Altitude Mode, hold down the [L/R] button will
activate fast sampling (sample per second) for five
minutes.
Temperature Display
!
In Temperature Display, the top display shows the
current temperature in degree Celsius ( C) or d e g r e e
Fahrenheit ( F).
IMPORTANT:
To get an accurate reading of air
temperature, you must take off the watch from the wrist
for 20 to 30 minutes which allows no body temperature
effect on your watch.
History Display
!
The Watch records the altitude readings automatically
on the hour, i.e 1:00, 2:00, 3:00 and etc. These
records are plotted into an altitude record graph.
!
In the History Display, the altitude record graph
shows in the top row of the display.
!
To review the altitude records for the last 23 hours,
press the [L/R] button to move the cursor to the left
cyclically, the corresponding altitude reading and its
time recorded (flashing) appear on the display
accordingly.
