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".
• 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" 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" or

"Manual Home Position Correction".

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
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.
• 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". If
this happens, press A to 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.
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 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.

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary
battery) that is charged by the electrical power produced by the solar cell. The
illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position
a watch with a resin band.
• Note that charging efficiency drops
when any part of the solar cell is
blocked by clothing, etc.
• You should try to keep the watch
outside of your sleeve as much as
possible. Even if the face of the watch
is blocked from light only partially,
charging will be reduced significantly.
