Operation Guide 3024

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 Bto toggle the button operation tone

 

 

on (MUTE not displayed) and off (MUTE displayed).

MUTE indicator

 

•Since the Bbutton 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.

•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.

To turn Power Saving on and off

1.In the Timekeeping Mode, hold down Auntil the city code starts to flash, which indicates the setting screen.

2.Press Bnine times until the Power Saving on/off

screen appears.

3. Press Cto toggle Power Saving on (ON) and off (OF).

4. Press Ato exit the setting screen.

• The Power Saving indicator (PS) is on the display in all modes while Power Saving is turned on.

On/Off status

Auto Return Features

•If you leave the watch in the Alarm Mode for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically.

•If you leave the watch with a flashing setting on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

Scrolling

The C and D 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 Atomic 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 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.

•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.

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 4.

•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.
