• The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.
Battery charges in the light. Battery discharges in the dark.

Charge
The electricity generated by the solar cell of the watch is
stored by a built-in battery. Leaving or using the watch

where it is not exposed to light causes the battery to run
down. Make sure the watch is exposed to light as much as
possible.
• When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced significantly if
the face is only partially covered.

• The actual level at which some functions are disabled depends on the watch model.
• Frequent display illumination can run down the battery quickly and require charging.
The following guidelines give an idea of the charging time required to recover from a
single illumination operation.
Approximately 5 minutes exposure to bright sunlight coming in through a window
Approximately 50 minutes exposure to indoor fluorescent lighting
• Be sure to read “Power Supply” for important information you need to know
when exposing the watch to bright light.

If the display of the watch is blank, it means that the watch’s Power Saving function
has turned off the display to conserve power.

• The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will use the watch normally. For more information, see
“To set your Home City” below.
• When using the watch in an area that is outside of the range of the transmitters in
Rugby and Mainflingen, you need to adjust the time manually as required. See
“Timekeeping” for information about manual settings.

Important!
• Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You also can perform manual receive or you
can set the time manually.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
This watch receives a time calibration signal and updates
its time setting accordingly. The time calibration signal
includes both Standard Time and Daylight Saving Time
(summer time) data.
• This watch is designed to pick up the time calibration
signal transmitted from Rugby, England and the signal
from Mainflingen, Germany.
Current Time Setting
This watch adjusts its time setting automatically in
accordance with a time calibration signal. You can also
perform a manual procedure to set the time and date,
when necessary.
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use C(east) and L(west) to select the city code you
l

Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
Make sure there are no metal objects nearby.
• The watch should not be on its side or facing the wrong way.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.
Inside or
among
buildings
• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to five minutes, but in some cases it
can take as long as 12 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 Rugby,
England and the signal from Mainflingen, Germany.
Reception Ranges
1,500 kilometers
Rugby
500 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.
• Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• See the information under “Signal Receive Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to six
times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. The start times of the auto receive operations depend
on the current Home City and DST settings.

Note
• Auto receive works only while the watch is in the Timekeeping Mode or World Time
Mode. Auto receive is not performed if an auto receive time is reached while an
alarm is sounding, while a countdown timer operation is in progress, or while a
setting screen (a screen with a flashing setting) is on the display.
• Auto receive 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 receive the signal easily.
• When auto receive is turned on, the watch receives the calibration signal for two to
five minutes everyday when the Timekeeping Mode time reaches each of the
calibration times. Do not perform any button operation within five minutes before or
after any one of the calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode. The receive operation will be performed whenever the display
shows any one of the calibration times, regardless of whether or not the
Timekeeping Mode time actually is the correct time.
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.
Receiving indicator
• 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 receive operations.
• Following reception of the time calibration signal and calibration of the watch’s time
setting, the Level 3 receiving indicator will remain on the display in all modes. The
Level 3 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.
• The Level 3 receiving indicator is displayed only when the watch is able to receive
both time and date data successfully. It does not appear when only time data is
received.
• The Level 3 receiving indicator indicates that at least one of the auto calibration
signal receive operations was successful. Note, however, that the Level 3 receiving
indicator is cleared from the display when the first auto receive operation of the day
is performed.

Probable Cause
• The watch is not in the Timekeeping
Mode.
• Your current Home City is not one of the
following city codes:
LIS, LON, BCN, MAD, PAR , MIL, ROM,
BER, STO, or ATH .
• You changed the time setting manually.
• The watch was not in the Timekeeping
or World Time Mode, or you performed
some button operation during the auto
receive operation.
• Even if receive is successful, the Level 3
receiving indicator disappears from the
display each day when the first auto
receive operation of the day is
performed.
• Time data (hour, minutes, seconds) only
was received during the last receive
operation. The Level 3 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
