Operation Guide 3034

The LOW indicator flashes on the display in the Timekeeping Mode when battery is at Level 3.

The LOW indicator at Level 3 and the flashing charge indicator (CHG) at Level 4 tell you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

At Level 5, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 4 (indicated by the flashing charge indicator) from Level 5. You will not be able to configure any of the other settings until the battery reaches Level 3 (no charge indicator) after dropping to Level 5.

Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to show a reading momentarily that is higher than the actual battery level. The correct battery power indicator should appear after a few minutes.

If you use the light or alarms a number of times during a short period, the recover indicator (RECOV) appears and the following operations become disabled until battery power recovers.

Illumination Beeper tone

Time calibration signal reception

After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.

Warning!

Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

On the dashboard of a car parked in direct sunlight

Too close to an incandescent lamp

Under direct sunlight

Charging Guide

After a full charge, timekeeping remains enabled for up to about 8 months.

The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.

Exposure Level (Brightness)
Approximate Exposure Time

 

 

Outdoor Sunlight (50,000 lux)

5 minutes

 

 

Sunlight Through a Window (10,000 lux)

24 minutes

 

 

Daylight Through a Window on a Cloudy Day

48 minutes

(5,000 lux)

 

 

 

Indoor Fluorescent Lighting (500 lux)

8 hours

 

 

Since these are the specs, we can include all the technical details.

Display on 18 hours per day, sleep state 6 hours per day

1 illumination operation (1.5 seconds) per day

10 seconds of alarm operation per day

10 minutes of signal reception per day

Stable operation is promoted by frequent exposure to light.

Recovery Times

The table below shows the amount exposure that is required to take the battery from one level to the next.

Timekeeping

Use the Timekeeping Mode to set and view the current time and date.

You can also use the Timekeeping Mode setting screen to specify the illumination duration and 12/24-hour format, to toggle power saving on and off, and to show or hide the date/day of the week on the main timekeeping screen.

In the Timekeeping Mode, you can press Ato change the display format as shown below. For information about what the main timekeeping screen looks like when the date and day of the week are not displayed, see “Hiding the Date/Day of the Week”.

Setting the Time and Date

Make sure you select your Home City code before you change the current time and date settings. World Time Mode times are all displayed in accordance with the Timekeeping Mode settings. Because of this, World Time Mode times will not be correct if you do not select the proper Home City code before setting the time and date in the Timekeeping Mode.

4.Press Ato exit the setting screen.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

The time calibration signals transmitted from Rugby and Mainflingen include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the received time signal.

The default DST setting is Auto DST (AT) whenever you select LIS, LON, BCN, MAD, PAR, MIL, ROM, BER, STO, or ATH as your Home City code.

If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually.

To change the Daylight Saving Time (summer time) setting

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

2.Press Band the DST setting screen appears.

3.Use Cto cycle through the DST settings in the sequence shown below.

Auto DST (AT) DST off (OFF) DST on (ON)

4. When the setting you want is selected, press Ato exit the setting screen.

The DST indicator appears to indicate that Daylight Saving Time is turned on.
