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

•Time calibration signal reception takes from four 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.

•This watch is designed to pick up the time calibration signal transmitted in the United States (Fort Collins, Colorado).

Reception Range

Fort Collins

•At distances further than about 600 miles (1,000 kilometers) from the Fort Collins transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also 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.

•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

The watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches 0:01 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch also will perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful. When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home Time Zone, and whether standard time or Daylight Saving Time is selected for your Home Time Zone.

Note

• The auto receive operation is performed only if the watch is in the Timekeeping

Viewing the Latest Signal Reception Results

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

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 Bthree

times.

 

•The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.

•Y (YES) continues to be indicated even if an attempt at manual receive fails after auto receive is successful.

•If you adjust the time or date setting manually, the second hand will move to N (NO).

Adjusting the Home Positions

If the time and date 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 is currently correct, it will move to the 12 o’clock position.

2. While in the Home Position Adjustment Mode, hold down Afor about five seconds. This will cause the second hand to make one revolution and stop at its current home position.

• The analog hands do not keep time during home

time is reached while you are configuring settings.

• Auto receipt of the calibration signal is 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 four 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 is actually the correct time.

To perform manual receive

1. Place the watch on a stable surface so its 9 o’clock side is facing towards a window.

2. In any mode, hold down Bfor about two seconds until the watch beeps.

3. When you release B, the second hand will move to R

(READY) to indicate that the watch is setting up for time

 

calibration reception.

 

• The second hand will move to W (WORK) and stay there

 

while actual reception is in progress.

 

• The hour and minute hands continue to keep time

 

normally.

 

• Time calibration signal reception takes from four to

 

seven minutes, but in some cases it can take up to 14

30

minutes. Take care that you do not perform any button

operations or move the watch during this time.

• If reception is successful, the second hand will move to Y (YES). One or two minutes later, the hands will move to the correct time.

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.

3. 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.

4. Press A to 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.

 

5. 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.

 

• You can change the hour and minute hand movement

direction to counterclockwise by pressing A. After that, each press of Bwill move the hour and minute hands counterclockwise in 10-second steps.

6. Press A to advance to date home position adjustment.

• The date indicator will show if the date home position is correct. Note that it can take up to 90 seconds before appears.

7. Check the date indicator.

8. If the date indicator shows something other than , it means that the date home position is off. If this happens, press Bto advance the date until appears.

• is located between 31 and 1.

9.Press A to exit home position adjustment.

• This causes the date to change to the current date, and the hour and minute hands to move to the current time.

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

• To return to the Timekeeping Mode, press B.

• 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.
