Time Calibration Signal Reception  
This watch is designed to pick up a time calibration signal transmitted from  
Mainflingen, Germany and update its time setting in accordance with the  
signal. There are two different methods you can use to receive the signal: Auto  
Receive and Manual Receive. With Auto Receive, the watch automatically  
receives the calibration signal three times each day and makes appropriate  
adjustments. With Manual Receive, you perform a specific button operation to  
receive the calibration signal.  
Current Time Setting  
Normally, you do not need to do anything to set the current time as long as you  
are within an area in West Europe where the watch can pick up the time  
calibration signal. You can also set the current time manually when you are  
outside the range of the signal.  
Before using the watch after purchasing it, use the procedure under  
“Selecting Your Home City Code” (page E-11) to specify your home city, and  
then use the procedure under “To perform manual time calibration signal  
reception.”  
Note that after you set your Home City code, you must also turn on the  
watch’s time calibration signal receiver if you want to enable auto time  
calibration. See “About Auto Receive” (page E-16) for more information.  
See “Setting the Time and Date Manually” for information about manual  
settings.  
Note  
If you are using the time calibration signal to set the time for this watch, be  
sure to correctly set your home city. Otherwise, there is the chance that the  
watch will not set the correct time. See the To select your Home City code”  
for details.  
This watch automatically switches between DST and standard time while  
BER is selected as the home city code. For any other home city code, you  
must perform the procedure under To set the current time and date  
manuallyto switch between DST and standard time.  
Time calibration reception is limited to specific geographic areas in West  
Europe.  
Setting the Time and Date Manually  
The times displayed in the Timekeeping Mode and World Time Mode are  
linked. Even if you plan to use the watch without enabling auto time calibration,  
be sure to select a Home City code (the city code whose time and date you are  
setting), before you set the time and date.  
The current time setting in accordance with the time calibration signal takes  
priority over any time settings you make.  
The watch is designed to automatically update the date and day of the week  
for the period January 1, 2000 to December 31, 2039. Setting of the date by  
the time calibration signal cannot be performed starting from January 1,  
2040.

signal transmitted from Mainflingen, Germany  
(located 25 kilometers southeast of Frankfurt).  
Signal reception is possible within the area  
represented by a circle with a radius of about 800  
kilometers.  
The display range of the stopwatch is 23 hours, 59  
minutes, 59.99 seconds.  
The stopwatch continues to run, restarting from  
zero after it reaches its limit, until you stop it.  
The stopwatch measurement operation continues  
even if you exit the Stopwatch Mode.  
All of the operations in this section are performed in  
the Stopwatch Mode, which you enter by pressing  
C (page E-4).  
Even when the watch is within the reception range,  
signal reception is impossible if the signal is  
blocked by mountains or other geological  
formations between the watch and signal source.

Frankfurt  
Signal reception is affected by weather, atmospheric conditions, and  
seasonal changes.  
The time calibration signal is bounced off the ionosphere. Because of this,  
such factors as changes in the reflectivity of the ionosphere, as well as  
movement of the ionosphere to higher altitudes due to seasonal atmospheric  
changes or the time of day may change the reception range of the signal and  
make reception temporarily impossible.  
This watch is designed to receive the signal transmitted from Mainflingen.  
This means that reception is best when the antenna built into the 12 oclock  
edge of the watch is facing towards Mainflingen. Note, however, that moving  
the watch while the time calibration signal receive operation is taking place  
will make stable reception impossible.

Think of the watch as acting like a TV or radio when it is receiving the  
calibration signal. When receiving indoors, move to a location as near as  
possible to a window. Proper signal reception can be difficult or even  
impossible under the conditions listed below.  
Near TVs, refrigerators, computers, or other household appliances  
Far away from broadcasting stations among ferro-concrete structures or near  
mountains  
Underground, in tunnels or in ferro-concrete buildings  
Near high-tension wires, neon signs, or radio stations with interfering  
frequencies  
Reference  
Near railroads, highways or airports  
This section contains more detailed and technical information about watch  
operation. It also contains important precautions and notes about the various  
features and functions of this watch.  
In trains or cars  
Radio interference can make signal reception impossible.  
Strong electrostatic charge can result in the wrong time being set.  
The daily alarm and hourly time signal do not operate during signal reception.  
If you are in an area where proper time calibration signal reception is  
impossible, the watch keeps time with the precision noted in Specifications.”  
Auto Return Features  
If you leave a screen with flashing digits or a cursor on the display for two or  
three minutes without performing any operation, the watch automatically  
saves anything you have input up to that point and exits the setting screen.  
If you leave the watch in Alarm, Day Counter, or Telememo Mode for about  
two minutes without performing any operation, it automatically changes to the  
Timekeeping Mode.  
World Time  
The current time in all World Time Mode cities is calculated in accordance  
with the Greenwich Mean Time (GMT) differential for each city, based on the  
current Home City time setting in the Timekeeping Mode.  
GMT differential is calculated by this watch based on Universal Time  
Coordinated (UTC) data.  
Data and Setting Scrolling  
The B and D buttons are used in various modes and setting screens to scroll  
through data on the display. In most cases, holding down these buttons during  
a scroll operation scrolls through the data at high speed.  
Backlight Precautions  
The electro-luminescent panel that provides illumination loses power after very  
long use.  
The illumination provided by the backlight may be hard to see when viewed  
under direct sunlight.  
Initial Screens  
When you enter the Alarm, Day Counter, World Time or Telememo Mode, the  
data you were viewing when you last exited the mode appears first.  
The watch may emit an audible sound whenever the display is illuminated.  
This is due to vibration of the EL panel used for illumination, and does not  
indicate malfunction.  
The backlight automatically turns off whenever an alarm sounds.  
Inputting Text  
The following describes how to input text in the Alarm, Day Counter, and  
Telememo Modes.  
To input characters  
1.When the cursor is on the display, use B and D  
to cycle through the available letters, numbers and  
symbols, in the sequence shown below.

cursor to the right.  
3. Repeat steps 1 and 2 to input the rest of the characters you want.  
Display Text  
Though you can input up to eight characters for Alarm text, Day Counter text  
and the Telememo name, only six characters can appear on the display at one  
time. Because of this, display screens switch alternately between the first six  
characters and the remaining two characters.  
Timekeeping  
Pressing D while setting the current time in the Timekeeping Mode resets  
the seconds count to zero. Pressing D while seconds count is in the range  
of 30 to 59 resets the seconds to 00 and adds 1 to the minutes. In the range  
of 00 to 29, the minutes count is unchanged.  
The day of the week is automatically displayed in accordance with the date  
(year, month, and day) settings.  
The year can be set in the range of 2000 to 2039.  
The watchs built-in full automatic calendar automatically makes allowances  
for different month lengths and leap years. Once you set the date, there  
should be no reason to change it except after you have the watchs battery  
replaced.  
12-hour/24-hour Timekeeping Formats  
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode  
is also applied in all other modes.  
With the 12-hour format, the P (PM) indicator appears to the left of the hour  
digits for times in the range of noon to 11:59 p.m. and the no indicator  
appears to the left of the hour digits for times in the range of midnight to  
11:59 a.m.  
With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
