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, 2001 to December 31, 2099. Setting of the date by the time
calibration signal cannot 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.
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 first signal auto search operation
after factory default settings are in effect,
or after the city code has been changed
Any case other than the above.
The watch does this:
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.
Timekeeping
• The year can be set in the range of 2001 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 current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC*) for each city,
based on your Home City time setting.
* 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.
World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
Illumination Precautions
• The illumination provided by the light may be hard to see when viewed under direct
sunlight.
• Illumination turns off automatically 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.
• Illumination may not turn on if the face of the watch is
more than 15 degrees above or below parallel. Make
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.
