Auto Hand Home Position Correction - Casio 4390 Manual

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 day must be performed manually, using the
procedure under "Manual Home Position Correction" (page E-44).
• 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-42) for more information.
• The auto hand home position correction operation can take up to three and a half
minutes to complete.
• 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-42) or "Manual Home Position Correction" (page E-44).
