adjust the current time manually when any other city is selected as the Home City.

■  

The 

2

 

Second Hand

 indicates N (NO) when I check the result of the latest receive operation.

Possible Cause

Remedy

Page

  

x

 You are wearing or moving the watch, or 
performing a button operation during time 
calibration signal receive operation.

  

x

 The watch is in an area with poor reception 
conditions.

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

E-18

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

See “Approximate Reception Ranges”.

E-17

The alarm time was reached during time 
calibration signal reception.

The alarm sounded during time calibration 
signal reception, causing reception to be 
canceled.

The calibration signal is not being transmitted 
for some reason.

  

x

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

  

x

 Try again later.

■  

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-19), which will 
cause the time to be adjusted automatically according to your currently selected Home City. If this results 
in the wrong time setting, check your Home City setting and correct it, if necessary (page E-27).

E-60

 What causes incorrect direction readings?

 

x

 The watch may have been exposed to magnetism. Calibrate the direction sensor.

 

x

 A nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel 
beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move 
away from such objects and try again.

 What causes different direction readings to produce different results at the same location?

 

x

 Magnetism generated by nearby digital noise sources (such as high-tension power lines) can interfere 
with the detection of terrestrial magnetism. Move away from the source of the digital noise and try 
again.

 Why am I having problems taking direction readings indoors?

A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism 
readings. Move away from the object causing the interference or take the direction reading outdoors.
Indoor direction readings are particularly diffi cult inside ferro-concrete structures. Remember that you will 
not be able to take direction readings inside of trains, airplanes, etc.

Charging

■  

The watch does not resume operation after I expose it to light.

This can happen after the power level drops to Level 3 (page E-13). Continue exposing the watch to light until 
the 

2

 

Second Hand

 starts moving normally (at one-second intervals).

 The 

2

 

Second Hand

 starts to move at one-second intervals, but then suddenly returns to moving 

at two-second intervals.

The watch probably is not suffi ciently charged yet. Continue keeping it exposed to light.

E-59

Digital Compass Mode

■  

An error is indicated during sensor operation.

Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal 
circuitry. The illustrations below how sensor mode errors are indicated.

 

x

 During digital compass operations, nearby strong magnetism can cause an 
error to be indicated.

 

x

 Move away from any potential source of strong magnetism and restart the 
measurement. See “Location” (page E-43). If an error is indicated when you 
restart the measurement, it probably means that there is a problem with the 
sensor or internal circuitry.

■   

Abnormal magnetism detection is indicated.

 

x

 Move away from any potential source of strong magnetism and try taking a 
reading again.

 

x

 If abnormal magnetism is detected again when you retry, it could mean that 
the watch itself has become magnetized. If this happens, continue to keep 
away from the source of strong magnetism, perform bidirectional calibration, 
and then try taking a reading again. For more information, refer to “To 
perform bidirectional calibration” (page E-40) and “Location” (page E-43).

Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized 
CASIO distributor as soon as possible.

E-58

■  

The current time setting is off by hours.

 

x

 Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page 
E-27).

■  

The current time setting is off by one hour.

 

x

 If you are using the watch in an area where time calibration signal reception is possible, see “To 
confi gure Home City settings” (page E-27).

 

x

 The period when summer time is applied in the location where you are using the watch may be 
different from the period set for your currently selected Home City. Use the procedure under “To switch 
between standard time and summer time manually” (page E-29) to switch from 

AUTO

 to 

STD

 (for standard 

time) or 

DST

 (for summer time).

■  

The time and date settings 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 indicator alignment. Adjust the watch’s hand and day indicator home 
position alignment (page E-55).

E-57

Troubleshooting

Hand Movement and Position

■  

I lost track of what mode the watch is in.

Refer to “Mode Reference Guide” (page E-24). To return directly to the Timekeeping Mode, hold down 

B

 at 

least two seconds.

■  

The hands of the watch suddenly start moving at high speed, even when I do not perform any 
operation.

This could be due to any one of the following causes. In all cases, the hand movement does not indicate 
malfunction, and should stop shortly.

 

x

 The watch is recovering from a sleep state (page E-15).

 

x

 The time setting is being adjusted following a successful auto time calibration signal receive operation 
(page E-16).

■  

The 

2

 

Second Hand

 is moving at two-second intervals.

■  

All the watch’s hands are stopped at 12 o’clock and none of the buttons work (

2

 

Second Hand

 

stopped at 57, 58, 59, or 00).

Power may be low. Expose the watch to light until the 

2

 

Second Hand

 starts moving normally, at one-

second intervals (page E-11).

■  

Hands suddenly stop moving. Button operation also is disabled.

The watch may be in the power recovery mode (page E-13). Do not perform any operation until the hands 
return to their normal positions (in about 15 minutes). The hands should return to their correct positions 
when normal operation returns. To help power recover, leave the watch in a location where it is exposed 
to light.

E-56

 To adjust home positions

1.  In the Timekeeping Mode, pull out the crown.

2.  Hold down 

C

 for at least fi ve seconds until the watch beeps and the 

2

 

Second Hand

 moves to 12 o’clock.

 

x

 Automatic home position adjustment of all of the hands (but not the 

6

 

Day Indicator

) will start.

 

x

 If all hands are at 12 o’clock (the proper home hand home position), 
advance directly to step 3.

 

x

 If the 

4

 

Upper Dial Hand

 is not pointing at 

24

, which is its home position, 

hold down 

A

 for about two seconds to move it there.

3.  Press 

B

.

 

x

 This enters the 

6

 

Day Indicator

 home position adjustment mode.

4.  Check the 

6

 

Day Indicator

 to confi rm that it is 

1

, which is its home position.

 

x

 If the 

1

 is not in the center of the 

6

 

Day Indicator

, rotate the crown to 

center it.

 

x

 Rotating the crown three full consecutive turns clockwise will cause the 

6

 

Day Indicator

 to start changing in a forward direction (increment).

 

x

 To stop 

6

 

Day Indicator

 movement, press any button.

5.  Push the crown back in to return to the Timekeeping Mode.

 

x

 This will cause the hands to return to their normal positions and resume 
regular timekeeping. Wait until everything stops moving before performing 
any other operation.
