The watch also has five Altitude Reference Points (REFERENCE HOME,
REFERENCE BASE 1, REFERENCE BASE 2, REFERENCE BASE 3, and REFERENCE
MAN-ALT) which allow you to set the altitude of a known location ahead of time,
and then re-calibrate your watch at that point with one push of a button.
ATTENTION: Sudden changes in barometric pressure can impact
your altimeter reading. If possible, re-calibrate to a known altitude
when drastic pressure changes occur.
NOTE: While setting an alarm, quickly scroll through the setting
values by holding down START/SPLIT (+) or STOP/RESET (-).
— The AM/PM value will (+) only appear if you have set the watch to
display the 12-hour format.
When the alarm is armed, a bar is shown in alarm and time of day
modes above the alarm icon.
CALIBRATION MODE
The WS4
™
watch has the ability to take extremely accurate measurements. You
should calibrate either the Altimeter (HOME) or the Barometer (BARO), and the
Weather Icon (WEATHER) prior to first use. And, as with any precision instrument,
you should calibrate frequently to maintain accuracy.
NOTE: For the best accuracy, choose the calibration method based on
the most accurate reference source available. For example, if you are
standing at a trail head and know the correct altitude, then the most
accurate calibration will be altitude. If you don’t know your altitude,
you can find out the current sea level pressure (published online or in
a newspaper) and calibrate the sensor to barometric pressure.
