 Even when the watch is within range of a transmitter, signal reception may be 

 

•

impossible due to the effects of geographic contours, structures, weather, the time 

of year, the time of day, radio interference, etc. The signal becomes weaker at 

distances of approximately 500 kilometers, which means that the influence of the 

above conditions becomes even greater.
 Signal reception may not be possible at the distances noted below during certain 

 

•

times of the year or day. Radio interference may also cause problems with 

reception.

go to the Daylight Saving Time system in the future, some functions of this watch 

may no longer operate correctly.

 Check to make sure the watch is in the regular timekeeping mode. If it isn’t, hold 

1. 

down C for about two seconds to enter the regular timekeeping mode.
 The antenna of this watch is located on its 6 o’clock side. Position the watch with

at night.
 The receive operation takes from 

 

•

two to seven minutes, but in some 

cases it can take as long as 14 

minutes. Take care that you do not 

perform any button operation or 

move the watch during this time.

 Signal reception may be difficult or even impossible under the conditions

described below.

 What you should do next depends on whether you are using Auto Receive or 

3. 

Manual Receive.

 Auto Receive: Leave the watch over night in the location you selected in step 2. 

 

•

See “Auto Receive” for details.
 Manual Receive: Perform the operation under “To perform manual receive”.

 

•

 With Auto Receive, the watch performs the receive operation each day 

 

•

automatically up to six times (up to five times for the Chinese calibration signal) 

between the hours of midnight and 5 a.m. (according to the Home City time). When 

any receive operation is successful, none of the other receive operations for that 

day are performed.
 The receive operation is not performed if a calibration time is reached while you are 

 

•

configuring settings.

 In the regular timekeeping mode, keep 

1. 

A

 depressed (for about two seconds) as 

the x Second Hand goes through the following sequence.

 Moves to the last signal reception result (

 

•

Y or N), then to READY (or R for some 

models).

 The 

2. 

x

 Second Hand indicates the operations the watch is currently performing.

@

When the x Second 

Hand is pointed here:

READY (R)

Watch is setting up for reception.

WORK (W)

Reception is in progress.

YES (Y)

Reception was completed 

successfully.

NO (N)

Reception failed for some reason.

 If signal reception is unstable, the 

 

•

x

 Second Hand may 

move between WORK (W) and READY (R).

 The receive operation is complete when the 

3. 

x

 Second 

Hand moves to YES (Y) or NO (N) for about five 

seconds, and then resumes regular timekeeping.

 When the receive operation is successful, the watch 

 

•

adjusts the time setting accordingly. It does not adjust 

the setting if the operation failed.

 To interrupt a receive operation and return to the regular 

 

•

timekeeping, press any button.
 If the 

 

•

x

 Second Hand is pointing to YES (Y) or NO (N), 

you can return to regular timekeeping by pressing A.

In the regular timekeeping mode, press A.

 The 

 

•

x

 Second Hand will move to YES (Y) for five 

seconds if the latest receive operation was successful, 

or NO (N) if it was not. After that, regular timekeeping 

will resume.

 The 

 

•

x

 Second Hand will indicate NO (N) if you have 

adjusted the time or date setting manually since the 

latest receive operation.
 If the 

 

•

x

 Second Hand is pointing to YES (Y) or NO (N), 

you can return to regular timekeeping by pressing A.

 Strong electrostatic charge can result in the wrong time setting.

 

•

 Even if a receive operation is successful, certain conditions can cause the time 

 

•

setting to be off by up to one second.
 The watch is designed to update the date and day of the week automatically for 

 

•

the period January 1, 2000 to December 31, 2099. Updating of the date by signal 

reception will no longer be performed starting from January 1, 2100.
 If you are in an area where signal reception is not possible, the watch keeps time 

 

•

with the precision noted in “Specifications”.
 The receive operation is disabled under any of the following conditions.
