CAUTION
・ T he watch may display the wrong time if it fails to receive radio signals properly because of interference.
The watch may also fail to receive radio signals properly depending on the location or radio wave receiving
conditions. In this case, move the watch to another place where it can receive radio signals.
・ W hen the watch is out of reception range, its accurate quartz movement (loss / gain: ± 15 seconds per
month on average) will continue to keep the time.
・ T he time signal transmission may be stopped during maintenance of the facilities of each transmitting station
or because of a lightning strike. In such a case, see each station's website for further information or contact

Even within the radio signal reception range, this watch may fail to receive a radio signal depending on
the condition (due to the infl uence of weather, geographical features, buildings, or direction). → Environments
in which it is Diffi cult to Receive a Radio Signal on page 94.
Outside of the radio signal reception range, this watch cannot receive a radio signal → Radio Signal

・ S et the watch to the time zone to Tokyo (Japan).
If the time zone is set to a region other than Tokyo (Japan), the watch will be unable to receive a
radio signal. Check that the time zone is set to Tokyo (Japan).

・ A ttempt to receive a Radio Signal in a diff erent time period (In the case of manual reception).
Receiving environments diff er 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 the watch is used in regions or places where it is unable to receive a radio signal, or if no successful
reception can be made even when following the above procedures, set the time and date manually.
