Radio-controlled Atomic Timekeeping Precautions

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

• The time calibration signal bounces 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.

• Even if the time calibration signal is received properly, certain conditions can

cause the time setting to be off by up to one second.

• The current time setting in accordance with the time calibration signal takes

priority over any time settings you make manually.

• The watch is designed to update the date and day of the week automatically for

the period January 1, 2000 to December 31, 2099. Setting of the date by the

time calibration signal will not be performed starting from January 1, 2100.

• This watch can receive signals that differentiate between leap years and non-leap

years.

• Though this watch is designed to receive both time data (hour, minutes, seconds)

and date data (year, month, day), certain signal conditions can limit reception to time

data only.

• If you are in an area where proper time calibration signal reception is impossible, the

watch keeps time within ±20 seconds a month at normal temperature.

• If you have problems with proper time calibration signal reception or if the time

setting is wrong after signal reception, check your current Home Time Zone, and

DST (summer time).

Transmitters

This watch is designed to receive the time calibration signal transmitted from

Mainflingen, Germany and the signal from Anthorn, England. You can configure the

watch to select the transmitter that has the strongest signal automatically.

In this case:

The watch does this:

The first signal auto search operation

after factory default settings are in effect,

or after the time zone has been changed

Any case other than the above.

Timekeeping

• The year can be set in the range of 2000 to 2099.

• The watch's built-in full automatic calendar 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 watch's battery replaced.

• The date will change automatically when the current time reaches midnight. The

date change at the end of the month may take more time than normal.

• The current time for all time zones in the Timekeeping Mode and Dual Time Mode is

calculated in accordance with the Greenwich Mean Time (GMT) differential of each

zone, based on your Home Time Zone time setting.

• GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC*) data.

* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully

maintained atomic (cesium) clocks that keep time accurately to within

microseconds. Leap seconds are added or subtracted as necessary to keep UTC

in sync with the Earth's rotation. The reference point for UTC is Greenwich,

England.

Illumination Precautions

• The illumination provided by the light may be hard to see when viewed under direct

sunlight.

• Illumination automatically turns off whenever an alarm sounds.

• Frequent use of illumination shortens the battery operating time.

Auto light switch precautions

• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of

your arm can cause frequent activation of the auto light switch and illuminate the

face of the watch. To avoid running down the battery, turn off the auto light switch

whenever engaging in activities that might cause frequent illumination of the face.

• Note that wearing the watch under your sleeve while the auto light switch is turned

on can cause frequent illumination of the face and can run down the battery.

• Illumination may not turn on if the face of the watch is

More than 15 degrees

more than 15 degrees above or below parallel. Make

too high

sure that the back of your hand is parallel to the ground.

• Illumination turns off in about one second, even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with

proper operation of the auto light switch. If illumination

does not turn on, try moving the watch back to the

starting position (parallel with the ground) and then tilt it

back towards your face again. If this does not work, drop

your arm all the way down so it hangs at your side, and

then bring it back up again.

• Under certain conditions, illumination may not turn on until about one second after

you turn the face of the watch towards you. This does not necessarily indicate

malfunction of the auto light switch.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light

switch, and does not indicate a problem with the watch.

Tachymeter

If your watch has a tachymeter bezel, you can perform the

Tachymeter bezel

steps below to calculate average speed after using the

Stopwatch Mode to measure the amount of time that it

takes to travel one kilometer (or one mile).

• Never try to perform stopwatch operations while you

are driving an automobile, riding a bicycle, or

operating any type of vehicle. Doing so is very

dangerous and can result in accident.

1 In the Stopwatch Mode, start an elapsed time

operation at any point you like.

2 Stop the elapsed time operation after you travel one

kilometer or one mile.

3 Your average speed will be the value that the second

hand is pointing to on the tachymeter bezel.

• The illustration shows an example where it took 50 seconds to travel one kilometer

by car. The second hand is pointing at 70, which indicates that the average speed is

70 kilometers per hour.

1. Checks the Mainflingen signal first.

2. If the Mainflingen signal cannot be

received, checks the Anthorn signal.

1. Checks the last successfully received

signal first.

2. If the last successfully received signal

cannot be received, checks the other

signal.

• See "Stopwatch" for details about using the stopwatch.

• The tachymeter can be used only when you are traveling by car or some other

means that can cover one kilometer or one mile within 60 seconds.
