Hiding the Date/Day of the Week
You can configure the watch so the date/day of the week does not appear on the main
timekeeping screen.
• Pressing A in the Timekeeping Mode will toggle between a calendar screen
(current date and day of the week) and the main timekeeping screen.
• If you leave the calendar screen displayed for two or three minutes without
performing any operation, the watch will return to the main timekeeping screen
automatically.

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.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
• Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the
display), hold down B to toggle the button operation tone
on (MUTE not displayed) and off (MUTE displayed).
MUTE indicator
• Since the B button is also the mode change button, holding it down to turn the
button operation tone on or off also causes the watch’s current mode to change.
• The MUTE indicator is displayed in all modes when the button operation tone is
turned off.
Power Saving Function
When turned on, the Power Saving function enters a sleep
state automatically whenever the watch is left in an area
where it is dark for a certain period. The table below
shows how watch functions are affected by the Power
Saving function.
Power saving indicator
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
• The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the
watch is already in the sleep state when 6:00 AM arrives, however, it will remain in
the sleep state.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.

On/Off status
Scrolling
The C and L buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.
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 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.
• 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.

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.
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 Rugby signal.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.
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 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 or when battery power drops to
Level 5.
• 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
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.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
• With the 12-hour format, the PM indicator (P) appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• 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.
