If the Power Saving indicator (PS) is flashing on the display, it means that the display is blank because the watch’s Power Saving function has turned it off to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

• The initial factory default setting is Power Saving on.

• The watch will recover from the sleep state if you move it

to a well-lit area or if you press any button.

• See “Power Saving Function” for more information.

• The operational procedures for Modules 3311 and 5052

are identical. All of the illustrations in this manual show Module 3311.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal: auto receive and manual receive.

• Auto Receive

With auto receive, the watch automatically picks up the time calibration signal five times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.

• Manual Receive

Manual receive lets you start time calibration signal reception with the press of a button. For more information, see “To perform manual receive”.

Important!

• When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side facing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

600 miles

• Under good reception conditions, signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.

• 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.

• At distances further than about 500 kilometers from the Fukushima and Fukuoka/ Saga 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

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 0:00 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 will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive are successful.

Note

• Auto receive is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display).

• When a reception starts, the second hand will move at high speed to the 12 o’clock position where it will stop until the reception is complete.

• 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 easily receive the signal.

, you can specify either 40kHz or 60kHz.

TYO

• When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the five calibration times. Do not perform any button operation within seven minutes before or after any of the five calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the time kept in the digital display. The reception will be performed whenever the display shows one of the five calibration times, regardless of whether or not the displayed time is actually the correct time.

• When two, three, four, or five receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.

About the Receiving Indicator

The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest.

Receiving indicator

Weak

(Level 1)

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal reception.

• The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving Indicator and Seconds Count screen only. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.

• The Level 4 receiving indicator indicates that at least one of the five calibration signal reception was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 3:00 a.m. each day.

To perform manual receive

• Time calibration signal reception normally takes from two to seven minutes. In Japan, however, reception can take up to 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

• After signal reception is complete, the display of the watch changes to the last signal screen.

Note

• To interrupt a reception and return to the Timekeeping Mode, press D.
