• Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
infl uence of the conditions listed above becomes even greater.
• 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.
Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
• As of July 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
• Using this watch in a country covered by a time calibration that is different from the countries it
supports may result in incorrect time indication due to local application of summer time, etc.

To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn't, hold down
D
for about two seconds to
enter the Timekeeping Mode. (page E-24)
2. The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing
towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.
• Signal reception normally is better at night.
• The receive operation 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 operation or
move the watch during this time.

3. What you should do next depends on whether you are using Auto Receive or Manual Receive.
• Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive”
below for details.
• Manual Receive: Perform the operation under “To perform manual receive” on page E-20.
Auto Receive
• With Auto Receive, the watch performs the receive operation each day automatically up to six times (up
to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to
the Timekeeping Mode time). When any receive operation is successful, none of the other receive
operations for that day are performed.
• When a calibration time is reached, the watch will perform the receive operation only if it is in the
Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is
reached while you are confi guring settings.
E-20
• You can use the procedure under “To turn auto receive on and off” (page E-21) to enable or disable
auto receive.
To perform manual receive
1. Use
D
to select the Receive Mode (
RC
) as shown on page E-24.
2. Hold down
A
until the second hand points to
READY
(or
R
on some
models).
• This indicates that the watch is ready for signal reception.
• After a short while, the second hand will move to WORK (or W on
some models) and signal reception will begin. Do not operate
any of the watch’s buttons until the second hand starts moving
normally again, which indicates that reception is complete.
• If signal reception is unstable, the second hand may keep moving
between WORK ( W) and READY ( R).
• OK will appear on the digital display if the receive operation is
successful, while Err indicates reception was unsuccessful.
• If the second hand remains at READY ( R), press any button to cancel
signal reception. Move the watch to a location where reception
conditions are better and try again.
3. Press
D
twice to return to the Timekeeping Mode.
Note
To cancel an ongoing signal receive operation, press any of the watch’s
buttons. This will return to the Receive Mode screen in step 1 of this
procedure.

Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time setting.
• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
• The watch is designed to update the date and day of the week automatically for the period January 1,
2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed
starting from January 1, 2100.
• If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in “Specifi cations” (page E-103).
• The receive operation is disabled under any of the following conditions.
– While power is at Level 3 (
L
) or lower (page E-11)
– While the watch is in the power recovery mode (page E-12)
– While a sensor operation is being performed
– When the watch is in the function sleep state (“Power Saving”, page E-14)
– While a hand home position adjustment operation is in progress (page E-86)
– While a countdown timer operation is in progress (page E-77)
• A receive operation is cancelled if an alarm sounds while it is being performed.
• The Home City setting reverts to the initial default of
TOKYO
(
TYO
) whenever the battery power level
drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the
Home City to the setting you want (page E-28) .
