Operation Guide 2911

• 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

may also cause problems with reception.

• Even when the watch is within the reception range of the transmitter, signal

reception is 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 Receive Troubleshooting” if you experience

problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch attempts to receive the time

calibration signal automatically up to six times. The start times of the auto receive

operations depend on the current Home City and DST settings.

• If all of the first three reception operations fail, the watch automatically performs a

fourth receive operation.

• If any of the remaining receive operations (4, 5, or 6) is successful, any remaining

receive operations are skipped.

• Auto receive is performed in accordance with the Timekeeping Mode time.

Note

• Auto receive works only while the watch is in the Timekeeping Mode or World Time

Mode. Auto receive is not performed if an auto receive time is reached while an

alarm is sounding, while a countdown timer operation is in progress, or if a setting

screen (a screen with a flashing setting) is on the display.

• 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.

• When auto receive is turned on, the watch receives the calibration signal for two to

six minutes everyday when the Timekeeping Mode time reaches each of the

calibration times. Do not perform any button operation within six 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 time kept 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

Timekeeping Mode time is actually the correct time.

• If more than one auto receive is successful, the watch uses the data from the last

successful receive to adjust settings. When only one reception is successful, the

watch uses the data of the successful reception.

• 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 receive operations.

• Following reception of the time calibration signal and calibration of the watch’s time

setting, the Level 4 receiving indicator will remain on the display in all modes. The

Level 4 receiving indicator will not be displayed if signal reception was unsuccessful

or after you adjust the current time setting manually.

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)

Strong

(Level 4)

• The Level 4 receiving indicator is displayed only when the watch is able to receive

both time and date data successfully. It does not appear when only time data is

received.

• The Level 4 receiving indicator indicates that at least one of the auto calibration

signal receive operations was successful. Note, however, that the Level 4 receiving

indicator disappears from the display each day when the second auto receive

operation of the day is performed.

To perform manual receive

1. Place the watch on a stable surface so its top (12

o’clock side) is facing towards a window.

2. In the Timekeeping Mode, hold down D for about two

seconds until the watch beeps.

• Release D and the message RC! appears to indicate

that signal reception has started.

• Time calibration signal reception normally takes from

two to six minutes, but in some cases it can take as long

as 12 minutes. Take care that you do not perform any

button operations or move the watch while time

calibration signal reception is in progress.

Receiving indicator

• After signal reception is complete, the display of the watch changes to the Last

Signal screen.

To configure auto receive settings

1. In the Timekeeping Mode, press D to display the last

signal screen.

•

The watch will return automatically to the Timekeeping

Mode if you do not perform any button operation for two

or three minutes after displaying the last signal screen.

2. Hold down A until the current auto receive setting

flashes. This is the setting screen.

• If the auto receive setting does not appear when you

hold down A, it means that the city code currently

selected for the Home City is for an area that does not

support calibration signal reception. You cannot turn

auto receive on or off in this case.

3. Use D to cycle through the settings shown below, until the one you want to use is

displayed.

DCF OFF

Setting status

qvtA : Auto receive on. The watch selects the transmitter whose signal is

strongest automatically. Signal reception can take up to 12 minutes when

this option is selected.

DCF : Auto receive on for reception of the Mainflingen signal.

MSF : Auto receive on for reception of the Rugby signal.

OFF : Auto receive off.

• For details about transmitters, see “Transmitters”.

4. Press A to exit the setting screen.

• To return to the Timekeeping Mode from the last signal screen, press D.

• For information about city codes that support signal reception, see “To set your

Home City”.

Note

• Manual receive operations are also performed based on the transmitter setting

(

qvtA, DCF, MSF) you select above.

• If auto receive is turned off, performing a manual receive operation receives the

signal that is strongest automatically.

To display the Last Signal screen

In the Timekeeping Mode, press D to display the Last Signal screen (indicated by

GET). The Last Signal screen shows the date and time of the last successful time

calibration signal reception.

Signal Receive Troubleshooting

Check the following points whenever you experience problems with calibration signal

reception.

Problem

Cannot perform

manual receive.

Auto receive is

turned on, but

the Level 4

receiving

indicator does

not appear on

the display.

Time setting is

incorrect

following signal

reception.

Probable Cause

•

The watch is not in the Timekeeping Mode.

• Your current Home City is not one of the

following city codes:

BER, PAR, or LON.

• You changed the time setting manually.

• The watch was not in the Timekeeping

or World Time Mode, or you performed

some button operation during the auto

receive operation.

•

Even if receive is successful, the Level 4

receiving indicator disappears from the

display each day when the second auto

receive operation of the day is

performed.

• Time data (hour, minutes, seconds) only

was received during the last receive

operation. The Level 4 receiving

indicator appears only when time data

and date data (year, month, day) are

both received.

• If the time is one hour off, the DST

setting may be incorrect.

• The Home City code setting is not

correct for the area where you are using

the watch.

What you should do

• Enter the Timekeeping Mode

and try again.

• Select BER, PA R, or LON as

your Home City.

• Perform manual signal receive

or wait until the next auto

signal receive operation is

performed.

• Check to make sure the

watch is in a location where it

can receive the signal.

• Change the DST setting to

Auto DST.

• Select the correct Home City

code.

• For further information, see “Important!” under “Time Calibration Signal Reception”

and “Radio-controlled Timekeeping Precautions”.

• This watch is designed to receive the time calibration signal transmitted from Rugby,

England and the signal from Mainflingen, Germany.
