About charging
■ How to charge the watch
Expose the dial to light to charge the watch.

To ensure optimal performance of the watch, make sure
that the watch is kept sufficiently charged at all 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 ºC and + 60 ºC.)
※ W hen first using the watch or starting to use the watch after it has stopped because of the
energy depletion, sufficiently charge the watch referring to the table on the page at the right.

Check if the reception was successful
2
(within five seconds.)
If a reception was successful:
The second hand points to Y
(Yes: the 10-
second position)
If a reception has failed: The
second hand points to N
(No: the 20-second
position)
※ I f the Button is pressed after five seconds have elapsed or while the second
hand is moving to display the reception results, the reception results display
function is cancelled and the watch returns to the TIME display mode.
Under the following situations, the energy of the watch is
likely to be depleted, resulting in stoppage of the watch.
・The watch is concealed under a sleeve.
・The watch is used or stored under conditions where it cannot be exposed to light for a long time.
If a reception was successful: The second hand points to Y
・ A radio signal has been received successfully. Use the watch without any adjustments.
※ When the watch is not displaying the precise time even after successfully receiving a radio signal
→ In this case, refer to Troubleshooting: Misalignment of the time and hands on P.150
If reception has failed: The second hand points to N.
・ Place the watch in a place where it can easily receive a radio signal, or change its direction.
Even within the radio signal reception range, this watch may fail to receive a radio
signal depending on the condition （due to the influence of weather, geographical
features, buildings, or direction）. → In this case, refer to Environments in which it is
difficult to receive a radio signal on P.106.
This watch is unable to receive radio signals outside a reception range → Radio
signal reception range indication on P.100
・ Make sure that the time difference is correctly selected before attempting radio signal reception.
If the time difference is set to a region other than Japan, China, U.S.A. or Germany the signal reception
function will not work. Check the time difference setting → How to select the time difference on P.116
・ Attempt to receive a radio signal in a different time period （In the case of manual reception） .
Receiving environments differ according to time periods even at the same place.
Due to radio signal characteristics, the watch is able to easily receive radio signals during nighttime hours.
・ I f you use the watch in a place or region outside the radio signal reception range or when the
watch cannot successfully receive radio signals, manually set the time.
How to manually set the time

The figures of Time required for charging the watch to start moving at one- second intervals are
estimations of time required to charge the stopped watch by exposing it to light until it moves at
steady one-second intervals. Even if the watch is partially charged for a shorter period, the watch
will resume one-second- interval movement. However, it may shortly return to two-second-interval
movement. Use the charging time in this column as a rough guide for sufficient charging time.
※ The second hand movement indicates the remaining amount of energy.
"CHECKING THE CHARGING STATUS BY THE MOVEMENT OF THE SECOND HAND" P.96
※ The required charging time slightly varies depending on the model of the watch.
