BEFORE USE
Check the charging status
The indicator hand position shows whether this watch is able or unable to receive GPS signals.
In addition, for the low charging state, the movement of the second hand shows the energy
depletion state in further detail.
＊GPS radio signal reception requires a lot of energy. Keep in mind to regularly charge the watch by expose to light.

How to charge the watch
Expose the dial to light to charge the watch.
Under the following situations, the energy of the watch is likely to
be depleted, resulting in stoppage of the watch.
・ T he watch is concealed under a sleeve.
・ T he watch is used or stored under conditions where it cannot be
exposed to light for a long time.
※ W hen charging the watch, make sure that the watch is not heated to a high
temperature. (The operational temperature range is between -10 ℃ and + 60 ℃.)
※ W hen fi rst using the watch or starting to use the watch after it has stopped because of
the energy depletion, suffi ciently charge the watch referring to the table on the page below.

The fi gures of Time required for charging the watch to start moving at 1-sec intervals are estimations of time
required to charge the stopped watch by exposing it to light until it moves at steady 1-sec intervals. Even if the
watch is partially charged for a shorter period, the watch will resume 1-sec interval movement. However, it may shortly
return to 2-sec interval movement. Use the charging time in this column as a rough guide for suffi cient charging time.
※ T he required charging time slightly varies depending on the design and the
dial color of the watch.
