Reference
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.
Auto Return Features
• If you leave the watch in the Alarm, Data Memory, or Hand Setting Mode for two or
three minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
• 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.
Data and Setting Scrolling
The A 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.
Initial Screens
When you enter the Alarm or World Time Mode, the data you were viewing when you
last exited the mode appears first.

Time Calibration Signal Reception
• This watch is designed to receive a time calibration signal originating from one of the
three transmitters listed below.
Location
Call Sign
Fort Collins, Colorado
WWVB
Fukushima, Japan
Fukuoka/Saga, Japan
• When you select one of the city codes shown below as your Home City code, the
watch sets up automatically to receive from the applicable transmitter. Time
calibration signal reception is not possible whenever any other city code is specified
as the Home City code.
• When you select TYO as your Home City code, the watch automatically selects
either the Fukushima signal (40kHz) or the Fukuoka/Saga signal (60kHz),
depending on which is stronger.
Home City Code
LAX, DEN, CHI, NYC
TYO
• Note that when TYO (Japan) is selected as the Home City code, you can specify one
of two different time signal transmitters.

kilometers
• Signal reception is possible within a radius of about 2,000 miles (3,000 kilometers)
from the Fort Collins transmitter.
• At distances further than about 500 kilometers from the Fukushima and Fukuoka/
Saga transmitter, the signal may become weak and reception may be impossible
under certain conditions.
General Precautions
• 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.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Even when the watch is within the reception range of the transmitter, 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.
• 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.
• Reception is best when the antenna built into the 12 o'clock edge of the watch is
facing in the general direction of the signal transmitter. 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. Place the watch near a window in a location where there are no nearby
metal objects.
• Proper signal reception can be difficult or even impossible under the conditions
listed below.
Inside or

• Do not move the watch or operate any of its buttons while signal reception is being
performed.
• This watch automatically receives a time calibration signal in the middle of the night,
when reception is best.
• Radio interference can make signal reception impossible.
• Strong electrostatic charge can result in the wrong time being set.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±15 seconds a month at normal temperature.
