roubleshooting

Cannot perform manual reception.

Cause:

Manual receive can be performed in the

T

imekeeping Mode only

.

Manual receive cannot be performed

while a timer operation is in progress.

The Home City is set to a city other than

TYO

 (T

okyo), 

NYC

 (New 

Y

o

rk), 

CHI

(Chicago), 

DEN

 (Denver), or 

LAX

 (Los

Angeles).

Corrective Measures:

Perform manual receive in the

T

imekeeping Mode.

Change the Home City to 

TYO

 (T

okyo),

NYC

 (New 

Y

o

rk), 

CHI

 (Chicago), 

DEN

(Denver), or 

LAX

 (Los 

Angeles).

Correctly set the Home City as detailed

under 

“Manually Setting the T

ime and

Date

”.

The receive (

) icon is not on the display even though auto

signal reception is turned on.

Cause:

The receive (

) icon appears after the

watch successfully receives the

calibration signal and adjusts the current

time setting.

A single receive operation was not

successful.

The watch is not in the T

imekeeping

Mode or W

o

rld 

T

ime Mode when an auto

reception time is reached.

Y

ou performed manual reception, which

clears the receive (

) icon from the display

.

Corrective Measures:

Check to make sure the watch is in a

location where it can receive the signal.

Place the watch in a location where

reception conditions are good.

Make sure that the watch is in the

T

imekeeping Mode or W

orld 

T

ime Mode

during the auto reception times.

Calibration Signal Reception

Precautions

Auto reception can be performed while the watch is in the

T

imekeeping Mode or W

orld T

ime Mode only

.

Signal reception cannot be performed while a timer operation is in

progress.

Receipt of a calibration signal causes the digital time to be

adjusted first, followed by adjustment of the analog time. In order

to ensure correct adjustment of the analog time, be sure to match

the analog time with the digital time before performing a signal

receive operation.

Operating any button while auto reception is in progress will

cause the watch to beep and then exit the receive operation.

Make sure you are within the range of the calibration signal

transmitter before performing the reception operation. Remember

that geographic contours, nearby buildings, the season, the time

of day can make reception impossible even when you are within

range of the transmitter

.

Proper reception may be impossible if there is something blocking

the signal. If reception is unsuccessful, try again.

This watch is designed to adjust its current time setting in

accordance with the calibration signal transmitted in Japan and

the United States only

. Note that you will need to make your own

adjustments when using this watch outside of Japan or the United

States, or in any area that is outside the range of one of the

receivable time calibration signal transmitters.

When the watch is unable to adjust its time signal using the

calibration signal for some reason, timekeeping accuracy is within

±

15 seconds per month.

Strong electrostatic charge can cause timekeeping error

.

Signal reception is cancelled if an alarm starts to sound while it is

being performed.

The watch

’s calendar shows dates up to the year 2099.

Attempting a receive operation after that causes an error

.

DST

 Indicator

If you cannot receive the calibration signal or if the current time

setting is incorrect after signal reception, check the current setup

of the watch.

The following are the watch

’s factory default settings, which are

configured automatically whenever you have the battery of the

watch replaced.

Auto switching (according to 

signal data)

T

ime setting is incorrect following signal reception.

Cause:

If the current time is advanced by one

hour

, it probably means that summer time

is turned on (indicated by the DST

indicator).

If there is a large error in the setting, it

probably means that the wrong Home

City is selected.

Corrective Measures:

Correctly configure the summer time and

Home City settings as detailed under

“T

urning Summer T

f”

 and

“Manually Setting the 

T

”.

Cannot configure signal reception settings.

DEN

 (Denver), or

Corrective Measures:

Select one of the above as the Home City

as detailed under 

“Manually Setting the

”.
