Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears first.
Radio-controlled Timekeeping Precautions
•Strong electrostatic charge can result in the wrong time being set.
•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.
•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.
•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 a time calibration signal cannot be performed starting from January 1, 2100.
•This watch can receive signals that differentiate between leap years and
•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.
•Normally, the signal reception date shown by the Last Signal screen is the date data included in the received time calibration signal. When only time data is received, however, the Last Signal screen shows the date as kept in the Timekeeping Mode at the time of signal reception.
•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 city code, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings.
Setting | Initial Factory Default |
City code | (Berlin) |
DST (summer time) 
(Auto switching)
Auto receive | ON (Auto receive) |
Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.
•The following explains how the watch determines which transmitter it should check first.

Timekeeping
•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.
•The day of the week is displayed automatically in accordance with the date (year, month, and day) settings.
•The year can be set in the range of 2000 to 2099.
•The watch’s
•The times for the Timekeeping Mode and all the city codes of the World Time Mode are calculated in accordance with each city’s UTC differential.
•The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England and the time zone where a city is located.
•The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which is the

•Illumination may be hard to see when viewed under direct sunlight.
•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.
•Illumination turns off automatically whenever an alarm sounds.
•Frequent use of illumination runs down the battery.
