The watch may have been exposed 
to magnetism or strong impact, which 
has caused problems with proper 
hand alignment.

Adjust the watch’s hand home positions.

■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal 
(page E-28), which will cause the time to be adjusted automatically according to your 
currently selected location. If this results in the wrong time setting, check your location 
setting and correct it, if necessary (page E-32).

 

■ Auto Receive is not performed or I cannot perform Manual Receive.

Your location setting is wrong.

Check your location setting and correct it, 
if necessary.

E-32

There is not enough power for signal 
reception.

Expose the watch to light to charge it.

■ The x Second Hand indicates N (NO) when I check the result of the latest 

 You are wearing or moving the 

 

x

watch, or performing a button 
operation during the signal receive 
operation.

 The watch is in an area with poor 

 

x

reception conditions.

Keep the watch in an area where reception 
conditions are good while the signal receive 
operation is being performed.

E-26

You are in an area where signal 
reception is not possible for some 
reason.

See “Approximate Reception Ranges”.

E-24

The calibration signal is not being 
transmitted for some reason.

 Check the website of the organization 

 

x

that maintains the time calibration signal 
in your area for information about its 
down times.

 Try again later.

■ The hands and/or day indications are off.
This could indicate that the watch has been exposed to magnetism or strong impact, 
which has caused problems with proper hand and day alignment. Adjust the watch’s 
hand and day home position alignment (page E-44).

 

■ The watch does not resume operation after I expose it to light.
This can happen after the battery charge level drops to Level 4 (page E-16). Continue 
exposing the watch to light until the 

x Second Hand starts moving normally (at one-

second intervals).
