Operation Guide 4321 4322

• If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your Home 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 Anthorn,

England and the signal from Mainflingen, Germany.

• The following explains how the watch determines which transmitter it should check first.

Module 4321

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 Anthorn signal.

1. Checks the last successfully received signal first.

2. If the last successfully received signal cannot be received, checks the other signal.

Module 4322

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 Anthorn signal first.

2. If the Anthorn signal cannot be received, checks the Mainflingen 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 automatically displayed 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.

• The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.

• GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC*) data.

* UTC 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.

The reference point for UTC is Greenwich, England.

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 P (PM) indicator 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

An LED (light-emitting diode) and a light guide panel illuminate the face of the watch for easy reading in the dark. In any mode, press B to illuminate the face of the watch for about one second.

• The illumination provided by the light may be hard to see when viewed under direct sunlight.

• Illumination automatically turns off whenever an alarm sounds.

• Frequent use of illumination shortens the battery operating time.
