10.4 Altimeter Mode - Sea Level Pressure Adjustment
Why Need to adjust the Sea Level Pressure
!As altitude is ca lc ul at ed by the difference
between current and sea level pressure, so the
sea level pressure changing or using the Watch
in a place which has a different sea level
pressure will affect the altitude reading.
!To achieve a more accurate reading, sea level
pressure need to be updated from place to p l a c e
and from time to time.
How to Adjust the Altimeter by Using Sea Level
Pressure Adjustment
!The Watch can adjust the current altitude reading by
sea level pressure adjustment.
!To adjust the Watch by using
, press the [S/S] button in
Display, and the sea level pressure
reading will appear.
!When sea level pressure reading is appeared,
press the [S/S] or [L/R] button to increase or
decrease the number to the target number. (Hold
down the button changes the number at a higher
speed).
!If the adjustment is completed, hold the [M]
bu tton to co nfirm ad justm ent and ex it the
adjustment display.

10.5 Altimeter Mode - Factory Default Adjustment
BAR O
How to Adjust the Altimeter by Using Factory
Default Adjustment
The Watch can also adjust the altitude reading
calculation back to using factory default value.
To adjust the Watch by using factory default
adjustment (restore to factory default by setting
sea level pressure to 1013.2mb), press the [S/S]
bu tton in Fac tory Default Display, and the
indicator "NO" will appear.
!When the indicator "NO" is appeared, press the
[S/S] or [L/R] button to select between "YES"
(reset the Watch to factory default) or "NO"
(abort the resetting).
!To exit Adjustment Display, hold the [M] button
for 2 seconds, and then the Watch will go back
to Altimeter Mode. If the "YES" Display is
selected when exiting the Adjustment Display, the
"DONE" Display will appear for 2 seconds prior
to the normal operation.

10.2 Altimeter Mode - Zero Altitude Adjustment
How to Measure the Relative Altitude
!The Watch can measure relative altitude, for
example, it can measure the ascending or the
descending altitude between the starting point
and the finish point of a trail.
!To measure the ascending or descending altit ud e
of a trail by setting the current altitude to 'zero'
mandatory (by below) at a reference point such
as the starting point of a trail. An ‘r’ indicator will
be appeared on the display.
Adjust the Altimeter by Using Zero Altitude
Adjustment
!
!To adjust the Watch by using
, press the [S/S] button in
Display, and the indicator "NO" will
appear.
!When the indicator "NO" is appeared, press the
[S/S] or [L/R] button to select between "YES"
(reset the Watch to zero) or " N O " ( a b o r t t h e
resetting). When "YES" or "NO" is selected, hold
the [M] button to confirm the setting.
!To exit Adjustment Display, hold the [M] button
for 2 seconds, and then the Watch will go back
to Altimeter Mode. If the "YES" Display is
selected when exiting the Adjustment Display, the
"DONE" Display will appear for 2 seconds prior
to the normal operation.
!To restore the Watch to factory default, please
refer to the coming section "Altimeter Mode -
Factory Default Adjustment" for more detail.
To select the Adjustment Display, hold the [M] button
in Altimeter Mode. Then press the [M] button to
select among the Zero Altitude, Absolute Altitude,
Sea Level Pressure and Factory Default Adjustment.

10.3 Altimeter Mode - Absolute Altitude Adjustment
Why the Altitude Need to be Adjusted
!As the absolute altitude is calculated from air
pressure, the change of air pressure would affect
the altitude reading.
!To achie ve a mo re acc ura t e re adi n g, the
WeatherMaster needs to be calibrated from time
to time as pressure may change gradually even
within hours.
Before Adjusting the Altitude
!Adjusting the altimeter at a place where the
altitude is determined, such as sea level (0m) or
beside an altitude sign pole (e.g., 89 m), because
that altitude will be inputted into the Watch during
the adjustment.
IMPORTANT: Input an incorrect altitude during the
adjustment, it results a mistaken altitude in future.

Altitude Adjustment
!The Watch can adjust the current altitude reading
to an absolute altitude value.
!To adjust the Watch by using
, press the [S/S] button in
Display, and the altitude reading will
appear.
!When altitude reading is appeared, press the
[S/S] or [L/R] button to increase or decrease the
number to the target one. (Hold down the button
changes the number at a higher speed).
!If the setting is completed, hold the [M] button to
confirm setting and exit the adjustment display.
!To select the Adjustment Display, hold the [M]
button in Altimeter Mode. Then press the [M]
button once again to select among the Zero
