■Receiving the radio signal
There are three ways to receive the radio signal.
This watch also incorporates a function to check last radio reception results.
→pages 14 and 15
Reception method Explanations
Automatic reception Receives the signal at 2:00 a.m. every day. If reception is unsuccessful,
the watch tries to receive at 3:00 a.m. and 4:00 a.m.
On demand
reception
Receive the signal manually when you want to adjust the time
and date. →page 24
Recovery automatic
reception
Receives the signal automatically after charging when the watch
stops due to insufficient charge.
• These reception operations take place only when the crown is in the closed
position 0and the watch is not moved.
• When the watch is in a low power state (second hand moving in two
second intervals), radio reception will not be attempted.
• Radio signal reception cannot be deactivated.
• Even when this watch receives a radio signal successfully, the accuracy of
the displayed time will be dependent on the reception environment and
internal processing.
• If the watch is not able to receive the signal, it will operate normally within
an accuracy range of ±15 seconds per month.
■During radio reception:
Remove the watch and place it on a stable surface
where it can receive the signal better, such as next to
a window.
• The reception antenna is located at the 6:00
position of the watch. Place the watch with the 6:00
position facing toward the station.
• While the watch is receiving radio signals (the second
hand indicates RX, H, M, or L), do not move the
watch as a successful update will not be acheived.
