• It is not necessary to operate buttons during automatic reception.
• The watch will automatically receive the radio wave every day at 2

<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.
WW4. 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, as a general rule, all of the hands will
stop. To check the time, hold the lower right button (A) for 2 seconds to cancel radio
wave reception. The hands will then return to the current time.
• Even while the radio wave is being received, the second hand will continue to rotate to
align the minute hand with the current time. This shortens the time it takes to set the
correct time.
An antenna for receiving the radio
signals is located inside the watch
(on the 9:00 position).
