Operation Guide 5095

••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.

−−Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

−−Shangqiu (China) transmitter: 500 kilometers (310 miles)

••As of January 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly.

••Using this watch in a country covered by a time calibration signal that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

To get ready for a receive operation

1.The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.

••Signal reception normally is better at night.

12 o’clock

••The receive operation takes from

two to seven minutes, but in some

 

or

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.

Radio-controlled Atomic Timekeeping Precautions

••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.

••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. −−While power is at Level 2 or lower

−−When the watch is in the function sleep state (“Power Saving”)

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

Auto Receive

••With Auto Receive, the watch performs the receive operation each day automatically up to three times between the hours of 2 a.m. and 4 a.m. (1 a.m. and 3 a.m. for the Chinese calibration signal). When any receive operation is successful, none of the other receive operations for that day are performed.

••When a calibration time is reached, the watch will perform the receive operation

TOKYO (TYO)

1.In the regular timekeeping, keep Adepressed (for about five seconds) as the x Second Hand and b Dual Time Minute Hand go through the sequence described below.

••x Second Hand: Last signal reception result → RC → Current location setting

••b Dual Time Minute Hand: 30 (Indicates the setting mode.)

2.Press Cto select the location you want.

••Each press of Ccycles through the three settings shown below.

**Select OFF for the location setting whenever using the watch in any other geographic area other than Japan or China. When OFF is selected, the watch does not receive any time calibration signal, so you will need to adjust the time setting manually as required.

only if it is in the regular timekeeping. The receive operation is not performed if a calibration time is reached while you are configuring settings.

To perform manual receive

1.In the regular timekeeping, keep Adepressed (for about two seconds) as the x Second Hand goes through the following sequence.

••Moves to YES (Y) or NO (N) to indicate the last signal reception result, then to Receiving (RC).

2. The x Second Hand indicates the operations the watch is currently performing.

When the x SecondIt means this:
Hand is pointed here:

 

Receiving (RC)

Reception is in progress.

YES (Y)

Reception was completed

successfully.

 

NO (N)

Reception failed for some reason.

 

 

3. The receive operation is complete when the x Second Hand moves to YES (Y) or NO (N) for about five seconds, and then resumes regular timekeeping.

••You can return to the regular timekeeping manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).

••When the receive operation is successful, the watch adjusts the time setting accordingly. It does not adjust the setting if the operation failed.

Note

••To interrupt a receive operation and return to the regular timekeeping, press any button.

To check the result of the latest receive operation

In the regular timekeeping, 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.

••You can return to the regular timekeeping manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).

Note

••The x Second Hand will indicate NO (N) if you have adjusted the time setting manually since the latest receive operation.

3.Press A. What happens next depends on the operations you performed in step 2, as described below.

••If you changed the location to TOKYO (TYO) to HONG KONG (HKG) from another setting, the watch will resume regular timekeeping when you press A.

••If you changed to OFF or if you did not change the setting, pressing Awill proceed to step 4, below.

4.Use the C(+1 minute) and B(–1 minute) buttons to change the current time setting.

••Holding down either button for about two seconds and then releasing it starts high-speed hand movement in the applicable direction.

••Pressing Cand Bat the same time will start high- speed hand movement, which will continue until the hands complete a 24-hour rotation.

••To stop high-speed hand movement, press any button.

••Check the v24-hour Hand to make sure that the time is set properly

(1:00 a.m. = 1 o’clock, 1:00 p.m. = 13 o’clock).

5.After the setting is the way you want, press A.

••This will exit the setting mode and the x Second Hand will resume regular timekeeping.

••For best timekeeping accuracy, press Aon a time signal from the TV or radio.

••The watch will exit the setting mode automatically if you do not perform any button operation for about two or three minutes.

Using Dual Time

Dual Time lets you keep track of the current time in another time zone.

••You can change the Dual Time setting in 30-minute (not 1-minute) increments.

Hand Functions

b Dual Time Minute Hand

n Dual Time Hour Hand

To configure the Dual Time setting

During regular timekeeping, hold down Cuntil the Dual

Time hands start to move.

••This will cause the Dual Time hand to advance by 30 minutes.

Note

••The Dual Time seconds are synchronized with regular timekeeping seconds.
