Manual Home Position Adjustment

Perform the procedure in this section if auto home position adjustment is not possible for some reason.

ξHand home position adjustment is not required if the time and day settings are correct.

Note

ξAny time after you enter the home position adjustment mode in step 2 of the following procedure, you can return to the Timekeeping Mode by pushing the crown back in. In this case, any adjustments you made before the watch returned to the Timekeeping Mode will be applied.

ξIf you do not perform any operation with the crown for about two minutes after pulling it out, crown operations will become disabled and hands will not move if you rotate the crown. If this happens, push the crown back in and then pull it out again.

To adjust home positions

1.Pull out the crown.

2.Hold down Bfor at least fi ve seconds until the watch

 

 

 

 

 

beeps and the x Second Hand moves to 12 o’clock.

 

 

 

 

 

ξ Automatic home position adjustment of all of the

 

 

 

 

 

hands (but not the n Day Indicator) will start.

 

 

 

 

 

ξ If all hands are at 12 o’clock (the proper home hand



 

 

 

 

 

 

 

 

 

home position), advance directly to step 3.

 

 

 

 

 

ξ If the v Upper Dial Hand is not pointing at 24, which

 

 

 

 

 

is its home position, hold down Afor about two

 

 

 

 

 

seconds to move it there.

 

 

 

 

 

E-81

3. Press C.

ξ This enters the n Day Indicator home position adjustment mode.



 

 

 

4. Check the n Day Indicator to confi rm that it is 1, which

 

 

 

 

 

 

 

 

is its home position.

 

 

 

 

 

 

 

 

ξ If the 1 is not in the center of the n Day Indicator,

 

 

 

 

rotate the crown to center it.

ξRotating the crown three full consecutive turns clockwise will cause the n Day Indicator to start changing in a forward direction (increment).

ξTo stop n Day Indicator movement, press any button.

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

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

Troubleshooting

Hand Movement and Position

I lost track of what mode the watch is in.

Refer to “Mode Reference Guide” (page E-32). To return directly to the Timekeeping Mode, hold down Cat least two seconds.

The x 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 (x Second Hand stopped at 57, 58, 59, or 00).

Power may be low. Expose the watch to light until the x Second Hand starts moving normally, at one-second intervals (page E-16).

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.

ξThe watch is recovering from a sleep state (page E-19).

E-83

ξThe time setting is being adjusted following a successful auto time calibration signal receive operation (page E-20).

Hands suddenly stop moving. Button operation also is disabled.

The watch may be in the power recovery mode (page E-17). 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.

The current time setting is off by hours.

ξYour Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page E-36).

The current time setting is off by one hour.

ξIf you are using the watch in an area where time calibration signal reception is possible, see “To configure Home City settings” (page E-36).

ξThe 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-39) to switch from AT (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-79).

Sensor modes

An error is indicated during sensor operation.

Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal circuitry. When this happens an error is indicated and the sensor operation cannot be performed. The illustrations below how sensor mode errors are indicated.

Digital Compass Mode

ξ During digital compass operations, nearby strong

magnetism can cause an error to be indicated.

 

 

ξ If the error is indicated during a measurement, restart the

 

measurement. If an error is indicated when you restart

 

the measurement, it probably means that there is a



problem with the sensor or internal circuitry.

 

E-86

Abnormal magnetism detection is indicated.

Digital Compass Mode

ξ Move the watch away from magnetic accessories,

electric devices, computers, and any other devices

 

 

that generate strong magnetism, and try performing the

 

sensor operation again.

 

ξ If abnormal magnetism detection is indicated again,



it may mean that the watch case may have become

magnetized or that magnetism conditions are completely

 

 

different from those where you last performed

 

bidirectional calibration. Perform bidirectional calibration

 

using the procedure under “To perform bidirectional

 

calibration” (page E-56).

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

E-87

What causes incorrect direction readings?

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

ξA 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?

ξMagnetism 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-16). Continue exposing the watch to light until the x Second Hand starts moving normally (at one-second intervals).

The x 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.

Time Calibration Signal

The information in this section applies only when LONDON (LON), PARIS (PAR), ATHENS (ATH), HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG KONG (HKG), or TOKYO (TYO) is selected as the Home City. You need to adjust the current time manually when any other city is selected as the Home City.
