■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy Page

Mode. Hold down C at least two seconds to
enter the Timekeeping Mode.
E-25
E-31
Your Home City setting is wrong.
Check your Home City setting and
correct it, if necessary. E-18
E-34
Auto time calibration signal reception
is OFF. Check the auto time calibration signal
reception setting.
E-27
A countdown timer operation is in
progress.
In the Countdown Timer Mode, stop the
timer operation and then return to the
Timekeeping Mode.
E-63
There is not enough power for signal
reception.
Expose the watch to light to charge it. E-12
E-78
■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal
(page E-25), which will cause the time to be adjusted automatically according to your
currently selected Home City. If this results in the wrong time setting, check your
Home City setting and correct it, if necessary (page E-34).
■ The current time setting is off by one hour.
Possible Cause Remedy Page
The period when summer time is applied
in the location where you are using the
watch may be different from the period
set for your currently selected Home City.
Use the procedure under “To switch
between standard time and summer time
manually” to switch from AT (AUTO)
to STD (for standard time) or DST (for
summer time).

■ The x Second Hand indicates N (NO) when I check the result of the latest
receive operation.
Possible Cause Remedy Page
You are wearing or moving the watch, x
or performing a button operation
during time calibration signal receive
operation.
The watch is in an area with poor
x
reception conditions.
Keep the watch in an area where
reception conditions are good while time
calibration signal receive operation is
being performed.
E-23
You are in an area where signal reception
is not possible for some reason.
See “Approximate Reception Ranges”. E-20
The alarm time was reached during time
calibration signal reception.
The alarm sounded during time
calibration signal reception, causing
reception to be canceled.
—
The calibration signal is not being
transmitted for some reason.
Check the website of the organization x
that maintains the time calibration
signal in your area for information about
its down times.
Try again later.

Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-14). Continue
exposing the watch to light until the
x Second Hand starts moving normally (at one-
second intervals).
The ■ x Second Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not suffi ciently charged yet. Continue keeping it exposed to
light.
Time Calibration Signal
The information in this section applies only when LONDON (LON), PARIS (PAR),
ATHENS (ATH), HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX),
DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC), HONG KONG (HKG), or
TOKYO (TYO) is selected as the Home City. You need to adjust the current time
manually when any other city is selected as the Home City.
E-75
Sensor
Temperature measurement error occurs. ■
This indicates that there is a problem with the sensor or the
watch’s internal circuitry, making sensor measurement and
value correction impossible.
If the error message appears during a measurement, x
restart the measurement. If the error message appears
when you restart the measurement, it probably means
that there is a problem with the sensor or internal
circuitry.
E-74
The period when summer time is applied in the location where you are using the x
watch may be different from the period set for your currently selected Home City.
Use the procedure under “To switch between standard time and summer time
manually” (page E-37) to switch from AT (AUTO) to STD (for standard time) or DST
(for summer time).
■ The time and date settings are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day indicator alignment. Adjust the
watch’s hand and day indicator home position alignment (page E-68).
E-73
The time setting is being adjusted following a successful auto time calibration x
signal receive operation (page E-18).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-15). Do not perform any
operation until the hands return to their normal positions (in about 15 minutes). The
hands should return to their correct positions when normal operation returns. To help
power recover, leave the watch in a location where it is exposed to light.
■ The current time setting is off by hours.
Your Home City setting may be wrong. Check your Home City setting and correct it, x
if necessary (page E-34).
■ The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is x
possible, see “To confi gure Home City settings” (page E-34).

Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-30). To return directly to the Timekeeping
Mode, hold down
C at least two seconds.
■ The x Second Hand is moving at two-second intervals.
■ All the watch’s hands are stopped at 12 o’clock and none of the buttons work
( x Second Hand stopped at 57, 58, 59, or 00).
Power may be low. Expose the watch to light until the x Second Hand starts moving
normally, at one-second intervals (page E-14).
■ The hands of the watch suddenly start moving at high speed, even when I do
not perform any operation.
This could be due to any one of the following causes. In all cases, the hand movement
does not indicate malfunction, and should stop shortly.
The watch is recovering from a sleep state (page E-17). x
E-71
Press 3. C.
This enters the x n Day Indicator home position
adjustment mode.
Check the 4. n Day Indicator to confi rm that it is 1, which
is its home position.
If the x 1 is not in the center of the n Day Indicator,
rotate the crown to center it.
Rotating the crown three full consecutive turns
x
clockwise will cause the n Day Indicator to start
changing in a forward direction (increment).
To stop
x n Day Indicator movement, press any button.
Push the crown back in to return to the Timekeeping Mode. 5.
This will cause the hands to return to their normal positions and resume regular x
timekeeping. Wait until everything stops moving before performing any other
operation.

E-70
To adjust home positions
Pull out the crown. 1.
Hold down 2. B for at least fi ve seconds until the watch
beeps and the x Second Hand moves to 12 o’clock.
Automatic home position adjustment of all of the x
hands (but not the n Day Indicator) will start.
If all hands are at 12 o’clock (the proper home hand x
home position), advance directly to step 3.
If the
x v Upper Dial Hand is not pointing at 24, which
is its home position, hold down A for about two
seconds to move it there.
