Analog Timekeeping

The analog time of this watch is synchronized with the digital time. The analog time setting is adjusted automatically whenever you change the digital time.

Note

•The hands for the analog timepiece move to adjust to a new setting whenever any of the following occurs.

When you change the digital time setting manually

When the digital time setting is changed by time calibration signal reception When you change the Home City code and/or DST setting

•If the analog time does not match the digital time for any reason, use the procedure described under “To adjust the analog time” to match the analog setting to the digital setting.

•Whenever you need to adjust both the digital and the analog time settings manually, make sure you adjust the digital setting first.

•Depending on how much the hands have to move in order to adjust to the digital time, it may take some time before they stop moving.

To adjust the analog time

1.In the Timekeeping Mode, press C five times to enter the Hand Setting Mode.

2. Hold down A until starts to flash, which indicates the setting screen.

•The second hand will move at high speed to the 12

o’clock position, where it will stop.

3. If the second hand is not pointing precisely at 12

o’clock at this time, use D to adjust its position.

• Each press of D causes the second hand to

advance by one second.

4. Press C. This will cause the time on the digital display to flash, which indicates that adjustment of hour and minute hands is selected.

5. Use D and B to adjust the analog setting as described below.

When you want to do this:	Perform this button operation:

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.

Power Saving Function

When turned on, the Power Saving function automatically enters a sleep state whenever the watch is left in an area 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 state.

Power Saving indicator

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

The sleep state is indicated by a blank screen with the Power Saving indicator (PS) flashing on it.

•Wearing the watch inside the sleeve of clothing can cause it to enter 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
	transmitter indicator starts to flash, which indicates the
	setting screen.
	• The second hand will move at high speed to the 12
	o’clock position, where it will stop.
	2. Press Aagain.
	3. Press Cseven times until the Power Saving on/off
On/Off status	screen appears.
	4. Press Dto toggle Power Saving on (ON) and off (OF).

5. Press Ato exit the setting screen.

• The second hand will advance at high speed to the correct position in accordance with the digital time seconds count, and resume normal movement from there.

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

Auto Return Features

•If you leave the watch in the Alarm or Hand Setting Mode, or with the Battery Level Indicator (HI or MID) displayed for two or three minutes without performing any operation, it automatically returns to the Timekeeping Mode.

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

Scrolling

The Band D buttons are used in various modes and setting screens to scroll through data on the display. 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 bounces 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 manually.

•The watch is designed to automatically update the date and day of the week 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 ±15 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 transmitter, current city code, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings.

Setting	Initial Factory Default
Transmitter	AT
City code	LON (London) (Module 3353)	BER (Berlin)
		(Module 3354/5053)
DST (summer time)	(Auto switching)
Auto receive	(Auto receive)

Transmitters

This watch is designed to receive the time calibration signal transmitted from Anthorn, England and the signal from Mainflingen, Germany. You can select either one of the transmitters, or you can configure the watch to automatically select the transmitter that has the strongest signal.

•The following explains how the watch determines which transmitter it should check first while the watch is configured for auto transmitter search (AT).

Module 3353

In this case:	The watch does this:
The first signal auto search operation	1. Checks the Anthorn signal first.
after factory default settings are in effect,	2. If the Anthorn signal cannot be received,
or after the city code has been changed	checks the Mainflingen signal.
Any case other than the above.	1. Checks the last successfully received
	signal first.
	2. If the last successfully received signal
	cannot be received, checks the other
	signal.
Module 3354/5053
In this case:	The watch does this:
The first signal auto search operation	1. Checks the Mainflingen signal first.
after factory default settings are in effect,	2. If the Mainflingen signal cannot be
or after the city code has been changed	received, checks the Anthorn signal.
Any case other than the above.	1. Checks the last successfully received
	signal first.

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

•Since the watch checks signals from both transmitters when AT is selected as the transmitter setting, signal reception can take as long as 14 minutes.
