Basic Operations
This section provides an overview of the watch
and explains operations that are common to
all modes.
Important!
●This watch is not a special-purpose
measuring instrument.
Measurement function readings are
intended for general reference only.
●Whenever using the Digital
Compass of this watch for serious
trekking, mountain climbing, or other
activities, be sure to always take
along another compass to confirm
readings. If the readings produced
by the Digital Compass of this watch
are different from those of the other
compass, perform bidirectional
calibration of the Digital Compass to
ensure better accuracy.
ーCompass readings and
calibration will not be possible if
the watch is in the vicinity of a
permanent magnet (magnetic
accessory, etc.), metal objects,
high-voltage wires, aerial wires, or
electrical household appliances
(TV, computer, cellphone, etc.)
lDigital Compass
●The watch’s Altimeter Mode
calculates and displays relative
altitude based on barometric
pressure readings produced by its
pressure sensor. Because of this,
altitude values displayed by the
watch may be different from your
actual elevation and/or sea level
elevation indicated for the area
where you are located. Regular
calibration in accordance with the
local altitude (elevation) indications
is recommended.
lAltitude Measurement
