COMPASS CALIBRATION
Since a compass uses the earth’s magnetic field,be aware of large metallic
objects,such as vehicles or bridges, or objects that give off electromagnetic
radiation,such as TVs or PCs, which could affect the magnetic field around the
watch. If compass is calibrated near such objects,it will only work properly in
that location. If compass is calibrated away from such objects,it will not work
properly near them. For best results, calibrate in area of intended use.
Also avoid areas that may exhibit higher than normal concentrations of hard
and soft iron, as they may cause inaccurate headings.Whenever a heading is
suspect, recalibrate.
In calibrating and taking headings, it is important,as with all compasses,to keep
compass level. Calibrating or taking a heading when watch is not level can
result in large errors.To keep watch level,hold watch so that bubble is centered
in bubble level window.
Do not store watch near any source of magnetism, such as computers,
appliances,or TVs,as watch can take on a magnetic charge,yielding inaccurate
headings.
To calibrate compass, keep watch level or place on level surface (if band
interferes,place on inverted cup) for entire procedure.Watch may be face
down, but take care to protect watch face. Go to Compass mode and then
press and hold SET.While level,SLOWLYrotate watch two revolutions,taking
at least 15 seconds per revolution.This is critical in achieving proper
calibration.To help you rotate watch at proper speed, a block is shown at
perimeter of display; rotate watch at a speed to keep block pointed in same
direction.When done, press MODE,keeping watch level.Watch displays current
declination angle setting (see DECLINATION ANGLE for more information).If you
do not wish to set declination angle,press DONE.Otherwise,press + or - to
select declination angle and then press DONE.
COMPASS
Compass mode provides an electronic compass reading.Press MODE
repeatedly until COMP appears.
Compass must be calibrated prior to use and calibration should be done in area
of intended use; see COMPASS CALIBRATION. If compass has not been
calibrated since battery replacement,watch displays PLEASE CAL, reminding
you to calibrate.
While holding watch level, using bubble level,press START/SPLIT or
STOP/RESET to activate compass.Watch displays heading in direction of
12 o’clock and virtual needle (one block at head and three blocks at tail) points
north. If watch is turned,heading updates and virtual needle rotates, always
pointing north.After 20 seconds, compass will automatically turn off to
conserve battery life.Press button again at any time to keep compass on for
another 20 seconds.
NOTE:While compass is on,INDIGLO® night-light may flicker slightly when on.
This is normal, as night-light must be turned off briefly during compass readings
to maintain accuracy.
USING THE COMPASS
Once compass is activated, as described above, there are two typical ways to
use virtual needle and turning compass ring.
Which way am I headed? Hold watch so that 12 o’clock is in direction of your
travel.Turn compass ring until virtual needle is pointing to north on ring.Your
heading is direction on ring at 12 o’clock.This should be the same direction
shown on display.
Which way should I go? If you know the direction you want to go (e.g., NE),
turn compass ring until that direction appears at 12 o’clock. Hold watch so that
you are facing 12 o’clock.Then,turn your body until virtual needle points to
north on compass ring.You are now facing the direction you want to go.
DECLINATION ANGLE
A compass detects “magnetic north,” which may be slightly different from “true
north,”which is used on maps.This difference,called the “declination angle,”
which varies around the globe,is typically small and can be ignored in many
cases.However,you may have watch automatically compensate by setting your
declination angle after compass calibration;see COMPASS CALIBRATION.With
proper declination angle set, heading will be more accurate and virtual needle
will point to true north.
