USER’S GUIDE 2367/2739

•This watch is designed to receive the signal transmitted from Mainflingen. This means that reception is best when the antenna built into the 12 o’clock edge of the watch is facing towards Mainflingen. Note, however, that moving the watch while the time calibration signal receive operation is taking place will make stable reception impossible.

•Think of the watch as acting like a TV or radio when it is receiving the calibration signal. When receiving indoors, move to a location as near as possible to a window. Proper signal reception can be difficult or even impossible under the conditions listed below.

Near TVs, refrigerators, computers, or other household appliances

Far away from broadcasting stations among ferro-concrete structures or near mountains

Underground, in tunnels or in ferro-concrete buildings

Near high-tension wires, neon signs, or radio stations with interfering frequencies Near railroads, highways or airports

In trains or cars

•Radio interference can make signal reception impossible.

•Signal reception is normally better at night than during the day.

•Strong electrostatic charge can result in the wrong time being set.

•The daily alarm and hourly time signal do not operate during signal reception.

•If you are in an area where proper time calibration signal reception is impossible, the watch keeps time within ± 15 seconds a month at normal temperature.

Timekeeping

•Note that you cannot switch between standard time and Daylight Saving Time while GMT is selected as the city code.

•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 2039.

•The watch’s built-in full automatic calendar automatically 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 is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on the your Home City time setting.

•GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data.

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 to the left of the hour digits for times in the range of noon to 11:59 p.m. and the no indicator appears to the left of the hour digits 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, with 24 indicator.

Backlight Precautions

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark.

In any mode, press Bto illuminate the display for about one second.

•The electro-luminescent panel that provides illumination loses power after very long use.

•The illumination provided by the backlight 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.

•The backlight automatically turns off whenever an alarm sounds.

•Frequent use of the backlight runs down the battery.

Sleep Mode

While the sleep mode is turned on, the watch automatically goes to "sleep" to save power whenever it is left in a place where lighting is dim (less than about 30 lux). The following shows how watch functions are affected when left in a dark place while in the sleep mode.

Approximate Period in		Functions
Sleep Mode
3 to 4 days	•	LCD off
	•	Alarm, hourly time signal, analog timekeeping and auto
		signal receive enabled
8 days or more	•	LCD off, alarm and hourly time signal disabled
	•	Analog timekeeping stopped at 12 o’clock
	•	Auto signal receive disabled

To exit the sleep mode, move the watch to a location that is more brightly lit, or press any button.

•It takes up to about five seconds for the watch to recover from the sleep mode.

•Even when the watch is in the sleep mode, digital-analog time coordination and auto signal receive are both performed.

•See “To set the current digital time and date manually” for information about

configuring sleep mode settings.
