• Normally, your watch should show the correct time as soon as you select

your Home City code. If it does not, it should adjust automatically after the
next auto receive operation (in the middle of the night). You also can
perform manual receive or you can set the time manually.

• The watch will receive the time calibration signal automatically from the

applicable transmitter (in the middle of the night) and update its settings
accordingly. For information about the relationship between city codes and
transmitters, see “Important!” under “Time Calibration Signal Reception”
and “Transmitters”.

• See the maps under “Approximate Reception Ranges” for information about

the reception ranges of the watch.

• You can disable time signal reception, if you want. See “To turn auto receive

on and off” for more information.

There are two different methods you can use to receive the time calibration
signal: auto receive and manual receive.

• Auto Receive
With auto receive, the watch receives the time calibration signal automatically
up to six times a day. When any auto receive is successful, the remaining
auto receive operations are not performed. For more information, see “About
Auto Receive”.

• Manual Receive
Manual receive lets you start a time calibration receive operation with the press
of a button. For more information, see “To perform manual receive”.

• When getting ready to receive the time calibration signal, position the watch

as shown in the nearby illustration, with its 12 o’clock side facing towards a
window. This watch is designed to receive a time calibration signal late at
night. Because of this, you should place the watch near a window as shown
in the illustration when you take it off at night. Make sure there are no metal
objects nearby.

• Make sure the watch is facing the right way.

• Proper signal reception can be difficult or even impossible under the

conditions listed below.

• Signal reception normally is better at night than during the day.

• Time calibration signal reception takes from two to seven minutes, but in

some cases it can take as long as 14 minutes. Take care that you do not
perform any button operations or move the watch during this time.

• Signal reception may not be possible at the distances noted below during

certain times of the year or day. Radio interference may also cause
problems with reception.

• Even when the watch is within the reception range of the transmitter, signal

reception will be impossible if the signal is blocked by mountains or other
geological formations between the watch and signal source.

• Signal reception is affected by weather, atmospheric conditions, and

seasonal changes.

• See the information under “Signal Reception Troubleshooting” if you

experience problems with time calibration signal reception.

The watch receives the time calibration signal automatically up to six times a
day. When any auto receive is successful, the remaining auto receive
operations are not performed.  The reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or
Daylight Saving Time is selected for your Home City.
