•
Signal reception is normally better at night than during the day.
•
Time calibration signal reception takes from two to seven minutes. Take care that
you do not perform any button operations or move the watch during this time.
•
This watch is designed to receive the time calibration signal transmitted from
Mainflingen, Germany. Signal reception is possible within the area represented by a
circle with a radius of about 1,000 kilometers.
•
At distances further than about 500 kilometers from a transmitter, signal reception
may not be possible during certain times of year or times of day. Radio interference
may also cause problems with reception.

problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 0:00 a.m., 1:00
a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will
also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled
auto receive are successful.
Note
•
Auto receive is performed only if the watch is in the Timekeeping Mode or World
Time Mode when one of the calibration times is reached. It is not performed if a
calibration time is reached while an alarm is sounding, or while you are configuring
settings (while settings are flashing on the display).
•
Auto receipt of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.
•
When auto receive is turned on, the watch receives the calibration signal for two to
seven minutes everyday when the time in the Timekeeping Mode reaches each of
the five calibration times. Do not perform any button operation within seven minutes
before or after any of the five calibration times. Doing so can interfere with correct
calibration.
•
Remember that reception of the calibration signal depends on the time kept in the
digital display. The reception will be performed whenever the display shows one of
the five calibration times, regardless of whether or not the displayed time is actually
the correct time.
•
When two, three, four, or five receptions are successful, the watch uses the data of
the last reception for calibration. When only one reception is successful, the watch
uses the data of the successful reception.

About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.
•
Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
•
Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal reception.
Receiving indicator

Strong
(Level 1)
(Level 4)
•
The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving
Indicator and Seconds Count screen only. The Level 4 receiving indicator is not
displayed if signal reception was unsuccessful or after manual adjustment of the
current time setting.
•
The Level 4 receiving indicator indicates that at least one of the five calibration
signal reception was successful. Note, however, that the Level 4 receiving indicator
is cleared from the display at 3:00 a.m. each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
2. In the Timekeeping Mode, hold down
D
for about two
seconds until the watch beeps.
3. Release
D
and
RC
flashes to indicate that signal
reception has started.

Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
Problem
Cannot
perform
manual
receive.
Auto receive
is turned on,
but the Level
4 receiving
indicator
does not
appear on
the
Timekeeping
Mode
display.
Time setting
is incorrect
following
signal
reception.
Probable Cause
•
The watch is not in the Timekeeping
Mode.
•
Your current Home City is not one of
the following city codes:
BER
,
PAR
,
or
LON
.
•
You changed the time setting
manually.
•
The watch was not in the
Timekeeping or World Time Mode,
or you were performing some button
operation during auto receive.
•
Even if reception is successful, the
Level 4 receiving indicator
disappears every day at 3 a.m.
•
Time data (hour, minutes, seconds)
only was received during the last
reception. The Level 4 receiving
indicator appears only when time
data and date data (year, month,
day) are both received.
•
If the time is one hour off, the DST
setting may be incorrect.
•
The Home City code setting is not
correct for the area where you are
using the watch.
What you should do
•
Enter the Timekeeping Mode and try
again.
•
Select
BER
,
PAR
, or
LON
as your
Home City.
•
Perform manual receive or wait until
the next auto receive is performed.
•
Check to make sure the watch is in a
location where it can receive the
signal.
•
Change the DST setting to Auto DST.
•
Select the correct Home City code.
•
For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Timekeeping Precautions”.
World Time
The World Time Mode digitally displays the current time in
30 cities (29 time zones) around the world.
•
Pressing
A
in the World Time Mode causes the
applicable city code to appear on the digital display for
about two seconds.
•
If the current time shown for a city is wrong, check your
Home City time settings and make the necessary
changes.
•
The watch will perform a signal reception even if it is in
the World Time Mode when a calibration time is
reached. If this happens, the World Time Mode time
settings will be adjusted in accordance with the
Timekeeping Mode’s Home City time.
•
All of the operations in this section are performed in the
World Time Mode, which you enter by pressing
C
.

Note that the DST/Standard Time setting affects only the currently displayed city
code. Other city codes are not affected.
Alarms
You can set three independent Daily Alarms. When an
alarm is turned on, the alarm tone sounds when the alarm
time is reached. You can also turn on an Hourly Time
Signal that causes the watch to beep twice every hour on
the hour.
•
The alarm and Hourly Time Signal operate in
accordance with the current digital time.
•
The alarm number (
AL1
