T

o

 check the result of the last signal

receive operation

In the T

imekeeping Mode, press the 

BBBBB

 button. This enters

the Receive Result Mode.

If the watch was able to perform a successful signal receive

operation since midnight, the second hand will move to GET

. If

the watch has been unable to receive any signal successfully

, the

second hand will move to NG.

T

o

 return to the 

T

imekeeping Mode, press the 

B

 button three

times.

The watch will also return to the 

T

imekeeping Mode if you do not

perform any operation for about two or three minutes.

GET

NG

The current receive result is cleared each day at midnight.

This means GET indicates successful signal reception since

the start of the current day

.

GET continues to be indicated even if an attempt at manual

receive fails after auto receive is successful.

Calibration Signal Reception

Precautions

Auto reception can be performed while the watch is in the

T

imekeeping Mode only

.

If the hands become misaligned for some reason, they may not

indicate the correct time, even if the time calibration signal is

received normally

. If this happens, use the procedure under

“Adjusting the Home Positions

” to adjust the home positions of the

hands and the date.

Pressing any button while auto reception is in progress will cause

the watch to beep and signal reception to stop.

Make sure you are within the range of the calibration signal

transmitter before performing the reception operation. Remember

that geographic contours, nearby buildings, seasonal conditions,

the time of day

, can even 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 only

. It

operates like a standard (non-radio controlled) watch outside of

the range of the receivable time calibration signal transmitters.

When the watch is unable to receive the time calibration signal for

some reason, timekeeping accuracy is within 

±

20 seconds per

month.

Strong electrostatic charge can cause timekeeping error

.

Signal reception is cancelled if the 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

.

Receiving the Calibration Signal

There are two methods you can use to receive the time calibration

signal.

Auto receive

(Reception is performed automatically at midnight,

1:00, 2:00, 3:00, 4:00 and 5:00 each morning.)

Manual receive

 (Y

ou initiate reception using a button operation.)

When any auto receive is successful, further auto receive

operations for that day are not performed.

Successful auto receive keeps timekeeping accurate.

T

o

reception

right side (9 o

’clock side, where the antenna is located) is facing a

window

.
