•If hand positions are off by one hour or more, correct them using the procedure under “To trigger the auto hand home position correction operation manually” (page E-46) or “Manual Home Position Correction” (page E-48).

To trigger the auto hand home position correction operation manually

•Perform the following procedure when the time setting is off.

	In the Timekeeping Mode, hold down D for about six
	seconds until the second hand completes one full
	revolution.
	• Though the second hand will stop momentarily about
30	three seconds after you hold down D, do not release
	the button yet. Wait until the second hand completes a

full revolution before you release D.

• To interrupt an ongoing correction operation and return to the Timekeeping Mode, press D again.

Manual Home Position Correction

Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able to perform the signal receive operation. If this happens, perform the following home position correction procedure.

• Hand home position correction is not required if the time and day settings are correct.

• You also can use auto hand home position correction (page E-45) to correct the home positions of the second, minute, and hour hands.

1. In the Timekeeping Mode, hold down D for about three seconds until the second hand stops. Release D at this time.

Auto Hand Home Position Correction

Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able to perform the signal receive operation. Auto hand home position correction corrects the hand position automatically.

•Auto correction is performed in the Timekeeping Mode only.

•The auto correction operation corrects the positions of the second, minute, and hour hands. Home position correction of the dial hands and day must be performed manually, using the procedure under “Manual Home Position Correction” (page E-48).

•Each hour, the watch performs automatic correction of the hand positions. Correction can be performed for error up to 55 minutes slow or 5 minutes fast.

•You also can trigger the auto hand home position correction operation manually, if you want. See “To trigger the auto hand home position correction operation manually” (page E-46) for more information.

•The auto hand home position correction operation can take up to three and a half minutes to complete.

•If you release D when the second hand stops the first time (after about three seconds) in the above operation, the watch will enter the manual home position

correction mode, which is described under “Manual Home Position Correction” (page E-48). If this happens, press Ato return to the Timekeeping Mode and then perform the above operation again.

The manually triggered auto home position correction operation performs the following two steps.

1.The hands will move automatically in order to determine the home positions of the watch.

2.After the hand home positions are determined, the watch will return to normal timekeeping automatically. This completes the correction operation.
