Operation Guide 3353 3354 5053

• The flashing charge indicator (

) at Level 3 tells you that battery power is very low,

and that exposure to bright light for charging is required as soon as possible.

• At Level 4, 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 2

after dropping to Level 4.

• Leaving the watch in direct sunlight or some other very strong light source can cause

the battery level indicator to temporarily show a reading that is higher than the actual

battery level. The correct battery level 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 (

) appears on the

display and the following operations become disabled

until battery power recovers.

Illumination

Beeper tone

Coordination between digital and analog timekeeping

Time calibration signal reception

Recover indicator

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

Note

• See “Transmitters” for more information.

• Auto DST (

A) can be selected only while BER , PAR, LON, or ATH is selected as the

Home City code. For more information, see “Daylight Saving Time (DST)” below.

• The auto receive setting is used for time calibration signal reception only. See

“About Auto Receive” for details.

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 Anthorn and Mainflingen includes 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 (

A) whenever you select BER, PAR, LON,

ATH as your Home City code.

• If you experience problems receiving the time calibration signal in your area, it is

probably 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 A until the transmitter indicator starts to

flash, which indicates the setting screen.

2. Press C twice and the DST setting screen appears.

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

4. When the setting you want is selected, press A twice to exit the setting screen.

• The DST indicator appears on the display to indicate that Daylight Saving Time is

turned on.
