Solar Charging Function About energy ■ Energy depletion forewarning function The energy depletion forewarning function is activated when the energy stored in the watch runs low. In such a case, the second hand moves at two-second intervals. If the watch continues to be in the state of two-second interval movement, the watch switches to five-second interval movement, followed by a completely stopped state. If the energy depletion forewarning function is activated, charge the watch sufficiently. How to charge the watch page 110 Standard charging time page 111 ※ Neither the buttons nor the crown can be operated while the second hand moves at two-second or five-second intervals（this is not a malfunction）. ※ While the second hand moves at five-second intervals, the hour and minute hands, date and day stop operating. ※ While the second hand moves at five-second intervals, the watch is unable to receive radio signals automatically. After the watch is charged sufficiently and the second hand returns to normal onesecond interval movement, conduct the manual reception of radio signals to set the watch to the correct time.（Refer to "How to set the time, date and day" on page 95.） 112
