・ If 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 and date.
How to manually set the time
→ P.143
How to manually set the date
→ P.146
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.108.
This watch is unable to receive radio signals outside a reception range → Radio
signal reception range indication on P.102
・ 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.118
・ 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.
・ A radio signal has been received successfully. Use the watch without any adjustments.
※ When the watch is not displaying the precise time and date even after successfully receiving a radio signal
→ In this case, refer to Troubleshooting: Misalignment of the time and hands on P.154 and Misalignment of the date on P.156.
If a reception was successful: The second hand points to Y

CAUTION
・ The 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.
・ When 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.
・ The time signal transmission may be stopped during maintenance of the facilities of the
(each) transmitting station or because of a lightning strike. In such a case, see the (each)
station's website for further information or contact SEIKO CUSTOMER SERVICE CENTER.
