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

•Time calibration signal reception takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

•When within range of the applicable transmitter, this watch can receive either the Germany (Mainflingen) or England (Anthorn) time calibration signals. See “Transmitters” for more information.

•At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interference also may cause problems with reception.

•Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.

•Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on the currently selected GMT differential, and whether standard time or Daylight Saving Time is selected for it.

Note

•The auto receive operation is performed only if the watch is in the Timekeeping Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while you are configuring settings.

•Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.

•The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

•Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

To perform manual receive

1. Place the watch on a stable surface so its 12 o’clock

side is facing towards a window.

2. In the Timekeeping Mode, hold down Afor about two

seconds until the second hand moves to READY (R).

To check the latest signal reception results

Enter the Receive Result Mode.

•If the watch was able to perform a successful signal

receive operation since midnight, the second hand will move to Y (YES). If the watch has been unable to receive any signal successfully, the second hand will move to N (NO).

• To return to the Timekeeping Mode, press A.

• The current receive result is cleared when the first auto

 

receive operation is performed on the following day. This

Y

means Y (YES) indicates successful signal reception

since the start of the current day.

 

N• If you have adjusted the time setting manually, the second hand will indicate N (NO) here.

Adjusting the Home Positions

If the time settings are wrong even after the time calibration signal is received normally, use the following procedure to adjust their home positions.

To adjust the home positions

1. Enter the Home Position Adjustment Mode.

• If the home position of the second hand currently is correct, it will move to the 12 o’clock position.

• The analog hands do not keep time during home position adjustment.

2. Check the position of the second hand.

• The second hand home position is correct if it is pointing at 12 o’clock.

• If the second hand is not pointing at 12 o’clock, it means that its home position is off. If this happens, press B to move the second hand clockwise in one- second steps, until it points at 12 o’clock.

3. Press Ato advance to hour and minute hand home position adjustment.

• If current hour and minute hand alignment is correct, they will both move to 12 o’clock.

4. Check the position of the hour and minute hands.

• If the hour and minute hands are not pointing at 12 o’clock, it means that their home position is off. If this happens, press Bto move the hour and minute hands clockwise in 10-second steps, until they point at 12 o’clock.

5. Press A to exit home position adjustment.

• This will cause the watch to return to the Timekeeping Mode. The hour, minute and second hands will indicate the current time.

• Note that all button operations are disabled while the hour and minute hands are moving.

•After you complete the home position adjustment procedure, place the watch in a location that allows good time calibration signal reception, and then perform a manual receive operation. See “To perform manual receive” for more information.

Use the Timekeeping Mode to set and view the current time. This section also explains how to set the current time manually.

•If you become confused and lose your way during the following procedures, simply put the watch down and do not perform any button operation for two or three minutes. This will cause the watch to enter the Timekeeping Mode (indicated by normal one-second movement of the second hand) automatically. After that, you can try performing the manual setting procedure again from the beginning.

N

Note

•To interrupt a receive operation and return to the Timekeeping Mode, press any button.

•If reception is not successful, the second hand will move to N (NO). One or two minutes later, the second hand will resume normal operation, without any adjustment of the hand setting.

•If the second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button.

Viewing the Latest Signal Reception Results

You can use the Receive Result Mode to check if signal reception was performed correctly.

To adjust the time setting manually

 

1. In the Timekeeping Mode, hold down A for about five

AM

seconds.

PM

• This operation causes the second hand to move to AM or

 

PM in accordance with the current time setting. This is the

 

setting mode.

 

• The hour and minute hands do not move in the setting

 

mode.

 

2. Press Bto move the time setting forward by one minute.

 

• Holding down Bfor about two seconds starts high-speed

 

hand movement. High-speed hand movement will continue

 

until the hands complete a 12-hour cycle, or until you stop

 

them by pressing B.

•If you exit the setting mode after changing the time setting, the second hand will restart timing from 12 o’clock (0 seconds) automatically.

•The AM/PM setting will not change even if you move the hour hand past 12 o’clock in step 2. Use step 3 below to switch between AM and PM.
