HOW TO SET THE TIME (RADIO SIGNAL RECEPTION)
If a reception was successful: The seconds hand points to Y
• A radio signal has been received successfully. Use the watch without any adjustments.
* When the watch does not display the correct time and date even after successfully receiving a radio signal, refer
to Troubleshooting.→ Misalignment of the time and hand positions P.98, and Misalignment of the date P.100
If reception has failed: The seconds 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, terrain, buildings, or direction). “Environments in which it
is difficult to receive a radio signal” → P.26
This watch is unable to receive radio signals outside the reception range. “Radio signal reception range
indication” → P.20
• Make sure that the time zone is correctly selected before attempting radio signal reception.
When the time zone is set to a region other than the radio signal reception range, radio signals cannot
be received. Check the selection of time zone.
“How to select the time zone (How to display the local time around the world)” → P.32
“Time zone display and time difference table” → P.34
• 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.
• 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.
