							As it is an inverse relationship between altitude and barometric pressure, if I wake at the same or lower elevation I can be confidentthe atmospheric pressure has remained constant. If I rise to a higheraltitude I need to be aware as there is a chance a low pressure ismoving in.” 
-Conrad Anker World-Renowned Mountaineer
BAROMETER MODEYour watch includes information about current and sea level pressure, high or
low barometric information, and changes in sea level pressure over the most
recent 36 hours. These features are useful for understanding changes in
weather. 
Operating the Barometer 
Once in BARO Mode, the watch automatically scrolls through: 
 Highest reached barometric pressure. 
 Lowest barometric pressure.  
4. Press MODE (NEXT) to advance to the next setting option. 
5. Press SET (DONE) to finish.
NOTE:  
The altimeter will display in either FT (feet) or M (meters) 
depending on which display unit you chose in Time Mode.  See page 14 for information on setting units of measurement. 
ATTENTION:   Your altimeter is sensitive to weather changes! Sudden 
changes in barometric pressure can change your altimeter reading by +/- 100 meters even if you have stayed in the same location. If possible, re-calibrate to a known altitude when drastic pressurechanges occur.  
You only need to calibrate barometer OR altimeter, since they rely  on the same pressure. See Calibration Mode on page 36 for moreinformation. 
“Before I curl into my sleeping bag I note the current altitude and baro-  metric pressure. In the few hours I sleep if I see a change in altitude orbarometric pressure I can get an idea of the coming weather patterns.

TEMPERATURE AND FORECASTIn TIME, ALTI, BARO, CHRONO, and TIMER Modes, your WS4™watch includes
information about temperature and forecast.  
The watch can predict the weather based on historical air pressure trends. 
Generally, if the air pressure is rising, the weather situation is considered to be
improving and is indicated by the sun icon. If the air pressure trend is falling,
then the weather situation is worsening and is indicated by showing the clouds
and/or precipitation icons. 
When worn on your wrist, the temperature reading is affected by body heat and 
may differ from the actual temperature by 10 degrees or more. Long periods of
exposure to direct sunlight may also affect accuracy. The watch can also   mea sure
the temperature in water, but make sure you don’t press any watch buttons under
water or this will compromise the watch’s water-resistance.

 Current barometric pressure and the corrected sea level pressure. 
When the watch reaches the current barometric display you can also:
Press START/SPLIT: Displays numeric 
current barometer reading or graphic
display of the sea level pressure over
the last 36 hours. 
Press and hold STOP/RESET: Reset 
accumulated barometer statistics to
zero to clear the memory.
NOTE:  The barometer will display in either MB (millibars) or In Hg 
(inches of mercury) depending on which display unit you chose in Time Mode. See page 14 for information on setting units of measurement.

COMPASS MODEThe WS4™watch includes an accurate digital compass that takes a reading 
every second when engaged and shows the compass reading as a number and
a cardinal heading along with a virtual compass needle. You must calibrate the
compass prior to first use and it’s also a good idea to calibrate it periodically to
maintain more accurate readings. For more information, see Calibration Mode
on page 36. 
Calibrating the Compass 
When using the compass, it’s important to keep your wrist at a level, horizon- 
tal position to help make compass readings more accurate. 
For the most accurate readings, avoid calibrating the compass near large 
metallic objects (such as electronics, cars, filing cabinets, and
anything else metal) since magnetic force in these objects may
interfere with the magnetic field and give you inaccurate
 compass readings. Note that the Indiglo
®night-light feature
does not work while calibrating the compass. 
Prior to calibrating the compass, remove the watch from your wrist, hold it in 
your hand and choose a declination angle from the table on the next page. 
NOTE:   At low temperatures, the display could appear sluggish. Refer 
to page 9 for operating temperature range. Increase temperature  surrounding watch to resume normal operation. 
NOTE:  For more accurate temperature readings, try wearing the  
watch outside your jacket or clipping it to your belt or pack (ideally  in an area not constantly exposed to the sun). You can also removethe watch from your wrist and put in shade for 15 to 30 minutes.
For information on calibrating your weather icon see Calibration Mode on 
page 36.

							TIP: Your watch would be a great tool for orienteering. You can use 
your compass to navigate way points and if you participate in an orienteering race, you can time yourself using the chronograph(see next section). 
CHRONO MODEYour watch includes a chronograph, which is a stopwatch function. The chrono
can track up to 100 hours and 99 laps. The data you collect while running the
chronograph can then be used to check your progress in Review Mode. 
(See page 30 for more information about Review Mode). 
Most watch buttons have multiple functions in Chrono Mode. Use the table 
along with your watch to explore the options. 
4. Press START/SPLIT or STOP/RESET to increase or decrease setting values to 
match your chosen declination angle.  
5. Press MODE to advance to the next setting option.
6. Press SET to finish.
If you see CAL OK at the end of the calibration process you have successfully 
 calibrated the compass. If you see CAL FAIL, repeat the calibration process.ATTENTION:   Calibration may fail if you rotate the watch too quickly or 
take longer than one minute to complete. Calibration may also fail if you are near objects that are magnetic.
Using the Compass 
After you have calibrated your compass, you will see the current compass 
 heading, cardinal points, and the digital compass needle when you enter Compass
Mode. After 30 seconds the compass reading times out and disappears from the
watch display to preserve battery life. Press START/SPLIT to display the current
heading for another 30 seconds.

make sure bad weather is not approaching. Once you’ve finished, you can check out information about your activity in Review Mode.
Laps and Splits 
When referring to lap times, this is the time for an individual segment of an 
activity. Split time is the entire time up to the current segment.
When the chrono is running, a bar is shown in chrono and time of day modes above the stopwatch icon. 
NOTE: 
Your chronograph can be a good tool for mountain  
biking, skiing, or trail running. You can take splits at specified trail points along the way, periodically check your altimeter to see howhigh you’ve climbed or descended, and even check the barometer to
