frequently to obtain GPS assist data
automatically. This shortens the time
required to receive GPS signals at the
start of activity measurements.
If you press (C) without waiting for
●
[GPS READY] to appear, a warning
screen appears and then activity
measurement starts using the watch's
accelerometer.
When performing measurements
using the accelerometer, your
movements are not tracked. To track
your movements during an activity,
make sure that [GPS READY] is shown
on the display before you start activity
measurement.

Press (E) to cancel the measurement
startup and return to the GPS
reception screen.
It takes about 15 seconds to about two
●
minutes after you press (C) in step 1
until activity measurement using GPS
signals becomes enabled. Under
some signal reception conditions, it
may take more than five minutes.
OPEN WATER SWIMMING uses GPS
●
to measure the distance you swim.
However, since GPS signals are
affected by the external factors
described below, it may not be
possible to record distances you swim
accurately.
Water surface reflects GPS signals,
ー
which affects measurement
accuracy.
GPS signals are difficult to receive
ー
underwater, so GPS signals are lost
whenever the watch is submerged.
To improve distance and route
measurement accuracy using GPS,
refer to the points below.
After successfully receiving GPS
ー
signals, wait a few minutes before
starting activity measurement. This
will allow the GPS sensor to warm up
and provide time for the watch to
download the necessary GPS
information.
When swimming, make sure that the
ー
wrist where you are wearing the
watch is above the surface of the
water. Depending on your
swimming style, distance and
trajectory may not be recorded
accurately.
Specify [HIGH] for the GPS signal
