Calendar display.
*To return to the Time/Calendar display manually,
press any of the buttons.
Checking the reception result
Look at the antenna mark in the Time/Calendar
display to check the reception result.
■AUTOMATIC TIME SETTING
The watch can maintain precise time by
automatically receiving a radio signal which
broadcasts the official time standard once a
day. A radio signal can be selected between
MSF and DCF77.
*MSF is the radio signal for broadcasting the
official time standard for the United Kingdom,
and DCF77 is for Germany. The watch can
receive MSF when it is placed within
approximately 800 km from the MSF transmitter,
and can similarly receive DCF77 when it is
placed within approximately 1,000 km from the
DCF77 transmitter, depending on conditions.
Automatic reception
The watch receives the selected radio signal
automatically to set the time. The signal can
be selected between MSF and DCF77 in the
Time/Calendar setting mode (Refer to “■HOW
TO SET THE TIME/CALENDAR”). Once the watch
starts receiving the radio signal, it will take about
5 minutes until the reception attempt is
completed. When the watch successfully
receives the signal, or if it fails to receive the
signal in about 5 minutes, the watch will return
to the Time/Calendar display.
*Turn the antenna of the watch (at the 12 o’clock
position) toward the direction of the transmitter
of the selected signal to facilitate signal
reception.
*Leave the watch where it can receive radio
signals during the automatic reception period
(starting from 3:00 AM, or starting again from 4:00
AM if the reception from 3:00 AM is not
successful).
*The watch receives radio signals in the same
way as a TV or radio. Keep the watch where it
can easily receive signals, for instance, close to
a window. Keep the watch away from objects
that cause radio static.
*Please note that the watch may be unable to
receive radio signals properly under the
following conditions.
a) Inside a building, between tall buildings,
underground
b) Close to overhead power lines, TV stations,
train cables
c) Close to home electrical appliances or OA
devices such as TV’s, refrigerators, air
conditioners, air cleaners, PC’s, fax machines
d) In places generating radio interference, such
as construction sites, airports, military bases
or in heavy traffic
e) Inside a vehicle, train, or airplane
f) Close to furniture made of steel, such as a
steel desk
Checking the receiving condition during
reception
Look at the antenna mark to check receiving
conditions during radio signal reception. If the
mark is turning with parabolas, a radio signal is
being successfully received. If parabolas
appear, but soon disappear, receiving
conditions are not sufficient for successful
reception. If no parabola appears, receiving
conditions are poor, or the watch is outside the
reception range, and the watch is unable to
receive the radio signal.
Reception successful (The watch was able to
receive a signal within the last 24 hours.)
Reception within last 24 hours failed (The watch
has failed to receive a signal within the last 24
hours, but succeeded in receiving a signal
during the last 5 straight days.)
Reception failed (The watch has failed to
receive a signal for 5 straight days.)
When the buttons are released, the watch
starts receiving a radio signal.
*In such a case, the watch will starts receiving
MSF and S1 is shown on the display.
2. After the watch succeeds in receiving a
radio signal, or if it fails to receive a signal in
about 5 minutes, it will return to the Time/
Calendar display.
*To return to the Time/Calendar display manually,
press any of the buttons.
