About the backlight

In any mode, press L to illuminate the display for about two seconds.

· The backlight of the watch employs an electro-luminescent (EL) panel,

which loses illuminating power after very long use.

· The illumination provided by the backlight may be hard to see when viewed

under direct sunlight.

· The watch will emit an audible sound whenever the display is illuminated.

This is caused by a transistor that vibrates when the EL panel lights up. It

does not indicate malfunction of the watch.

· The backlight automatically turns off whenever an alarm sounds.

· The backlight remains lit for about two seconds from the point you press

L , even if it is already lit when you press L . If you keep L depressed for

about 15 seconds, the backlight will automatically turn off.

TIME CALIBRATION SIGNAL RECEPTION

This watch is designed to pick up a time calibration signal that is being

transmitted from Mainflingen, Germany and update its time setting in accord-

ance 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 twice each day and makes

appropriate adjustments. With manual receive, you perform a specific but-

ton operation to receive the calibration signal.

Important!

· 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 set your home city data" for

details.

· Time calibration reception is limited to specific geographic areas in Europe.

See "Time calibration signal reception precautions" for details.

· 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, 1995 to December 31, 2039. Setting of the date by

the time calibration signal cannot be performed starting from January 1,

2040.

· This watch can receive signals that differentiate between leap years and

non-leap years.

· After the watch successfully receives time calibration signal data, it first

applies it to adjust the digital time setting and then adjusts the analog

setting to match the digital time. If, for any reason, the digital time does not

match the analog time, use the procedure described under "HAND

SETTING MODE" to match the analog setting with the digital display.

· Auto receive is turned on when the watch is shipped from the factory.

To set your home city data

You can make Auto Receive on/off, DST (daylight saving time), and GMT

differential settings for your home city (the city where you normally use the

watch). This data can be changed any time you move to another geographic

area.

1. Press B while in the Timekeeping Mode.

The current Auto Receive on/off setting

flashes on the display because it is

selected.

· The receive indicator flashes along with the

current on (

ON) /off ( OFF) setting.

2. Press D to toggle Auto Receive on and off.

3. Pressing C

to changes to another

selection in the following sequence.

4. Press C until the DST indicator is flashing on the display along with the

current auto receive setting (

AUTO, ON, or OFF).

· AUTO Setting

Daylight saving time is activated and cancelled automatically in accordance

with time calibration signal data. Use this setting if you plan to use the

watch in an area where the daylight saving time period starts and ends on

the dates used in Germany.

· ON Setting

One hour is added to the current time indicated by the time calibration signal

and adjusted in accordance with the GMT time differential setting you make.

· OFF Setting

Daylight saving time is not applied.

5. Use the A and D buttons to change the DST setting in the sequence

shown below.

6. After making the setting you want, press C until the

GMT indicator

appears on the display.

· The value to the right of the GMT indicator is the time differential from

Greenwich Mean Time. This value is based on standard times only, and it

does not allow for daylight saving time (summer time).

7. Use the A and D buttons to change the GMT differential setting in the

sequence shown below.

8. After making all the home city settings you want, press B to return to the

Timekeeping Mode.

Time calibration signal reception precautions

· This watch is able to receive the time

calibration signal being transmitted from

Mainflingen,

Germany

(located

kilometers southeast of Frankfurt). Signal

reception is possible within the area

represented by a circle with a radius of

about 1200 kilometers.

· 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.

· Signal reception is affected by weather, atmospheric conditions, and

seasonal changes.

· At long distances that are out of the line of sight of the signal transmitter, the

signal is bounced off of 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 o'clock 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.

· Proper signal reception can be difficult or even impossible under the

conditions listed below. When receiving indoors, move to a location as near

as possible to a window. Think of the watch as acting like a TV or radio

when it is receiving the signal.

Nearby 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.

Near railroads, highways or airports.

In trains or cars.

· Radio interference can cause incorrect signal reception.

· Strong electrostatic charge can result in the wrong time being set.

· The analog hands do not move during signal reception. The analog hand

setting is changed based on the digital time setting after the time calibration

signal is successfully received.

· The daily alarm and hourly time signal do not operate during signal

reception.

· The receive indicator (

) flashes on the digital display while a signal

receive function is in progress.

· The watch initially changes the digital time setting to match the data

(German time) received in the time calibration signal. Next, it adjusts the

received time in accordance with the GMT differential setting. Finally, the

analog hands are adjusted in accordance with the digital time setting.

To perform manual time calibration signal reception

1. In the Timekeeping Mode, hold down A

until the figures in the digital display are

cleared (about three seconds).

2. Release A to start time calibration signal

reception, which is indicated by the flashing

receive indicator.

· Time calibration signal reception takes from

8 to 15 minutes.

· When the receive operation is successful, the

message LAST RECEIPT appears on

the display together with the received time

and date for about one or two minutes. Next,

the watch returns to the Timekeeping Mode.

· When the receive operation is unsuccessful,

the message

ERROR appears on the

display together with the date and time of

the last successful receipt for about one or

two minutes. Next, the watch returns to the

Timekeeping Mode.

· Pressing A while the LAST RECEIPT or ERROR message is on

the display returns to the Timekeeping Mode.

· To interrupt a receive operation and return to the Timekeeping Mode, press A .

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the

time calibration signal when the digital time in the Timekeeping Mode reaches

2:00 AM and 4:00 AM each day (calibration times).

· The Auto Receive operation 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 the time is reached while you are making

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 digital 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.

· The receive indicator (

) indicates that at both or at least one of the last

calibration time receipt attempts were successful.

· When auto receive is turned on, the watch receives the calibration signal for

8 to 15 minutes each day when the digital time reaches 2:00 AM and 4:00

AM. Do not operate any of the watch's buttons within 15 minutes prior to or

following the calibration times. Doing so can interfere with correct

calibration.

· Remember that receipt of the calibration signal depends on the time shown

on the digital display. The receive operation will be performed whenever the

digital display shows 2:00 AM and 4:00 AM, regardless of whether or not

that is actually the correct time.

· When both receipts are successful, the watch uses the data of the second

receipt for calibration. When only one receipt is successful, the watch uses

the data of the successful receipt.

To turn auto receive on and off

1. Press B while in the Timekeeping Mode. The current Auto Receive on/off

setting flashes on the display because it is

selected.

· The receive indicator flashes along with the current on (ON) /off (OFF)
