<Receiving the radio signals>
1. Remove the watch from your wrist and place on
a stable surface in a location, such as near a
window, from which radio waves can be easily
received, pointing the 9:00 side (reception
antenna position) in the direction of the radio
wave transmitter.
2. The watch will automatically receive the radio
wave every day at 2 a.m.
If it successfully receives the wave, reception is
not performed at 3 a.m. and 4 a.m.

4. Radio Signal Reception
Three types of radio signal reception are possible: automatic reception, on demand
reception and recovery automatic reception.
There are three modes where reception is possible: time (TME), calendar (CAL) and
receive set (RX-S). The watch cannot receive signals in any other mode.
Display the home city in digital display 2 when receiving the radio wave.
• Reception is not possible unless the crown is in the normal position.
• If the home city is “UTC”, reception is not possible.
• Reception is not possible during chronograph or timer measurement.
• The reception level may change depending on the surrounding environment. While
referring to reception level (H, M or L), change the watch location, direction and angle
to try to receive the radio wave.
• When the watch is receiving the radio wave signal, all of the hands will stop.
To check the time, hold the lower right button (A) for 2 seconds to cancel the radio
wave reception. The hands will then return to the current time.
An antenna for receiving the radio
signals is located inside the watch
(on the 9:00 position).
