To start HS2 high-speed movement

While HS1 high-speed movement is in progress, rotate the crown rapidly three
turns again in the same direction as the current HS1 movement (away from you
for forward movement).

To stop high-speed movement

Rotate the crown in the direction that is opposite that of the current high-speed
movement or press any button.
Note
You can use HS1 high-speed movement to perform the operations below.
Timer start time setting, alarm time setting, manual time setting, hand home position adjustment
You can use HS2 high-speed movement to perform the operations below.

Function Limitations Due to Temperature
The functions listed below become disabled whenever the temperature of the watch is outside the
approximate range of –10ºC to 60ºC (14°F to 140°F).
− GPS signal and/or time calibration signal reception
− Operation tones, and count down timer and alarm tones
− Illumination
− Hand and Day home position correction
E-18
If the time and date settings are incorrect
If the watch's time and date settings are not correct after you fi nish performing the procedure above, it
could mean that the watch's hands and/or date indicator positions are out of alignment. If this happens,
perform the home position adjustment procedure (page E-67).
Note that an internal decoding process the watch performs after it receives a signal may cause the
time setting to be slightly off (by less than one second). Performing the home position adjustment
procedure does not correct this condition.
If time and date settings still are not correct, try performing the steps below.
Confi gure the Home City (Time Zone) setting (page E-59) and the summer time setting (page E-60).
Refer to the "City/Time Zone Indicators and Time Offset Table" (page L-3) to select your Home City
(Time Zone).
Use one of the procedures below.
Perform the GPS signal time information receive operation to confi gure time settings (page E-34).
Perform the time calibration signal auto receive operation to confi gure time settings (page E-36).
Perform the GPS signal auto receive operation (page E-32).
Important!
A time calibration signal can be received in specifi c geographic areas only. See "Time Calibration
Signal Reception Ranges and Conditions" (page E-37).

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Important!
This watch uses a special secondary battery.
− Charging will not be possible if the watch's temperature is outside the approximate range of
approximately –10°C to 60°C (14°F to 140°F).
− Over-discharge will occur if the watch is not charged within approximately three months after it stops
operation due to low battery power. Charging may not be possible after over-discharge occurs. See
"Power Levels" (page E-24).
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
E-22
Operation Guide 5410
When wearing the watch, make
sure that its face is not blocked
from light by the sleeve of your
clothing.
The watch may enter a sleep
state (page E-27) if its face is
blocked by your sleeve even
only partially.

Checking the Charge Level

Check the charge level by observing the 1 Second Hand position immediately after entering the
Timekeeping mode.
See "Mode Reference Guide" (page E-42).
12 o'clock 2 o'clock
The watch is charged.
The conditions below indicate low battery power. Expose the watch to light to charge.
− Second hand jumping at two-second or fi ve-second increments
See "Charging the Watch" (page E-22) and "Power Levels" (page E-24).
Important!
Even if the 1 Second Hand is in the 12 o'clock (0-second) or 2 o'clock (10-second) position, it is
recommended that you normally keep it exposed to light.
Confi guring Time and Date Settings
Perform the procedures in this section when the time and date settings of your watch are not correct.
Important!
Before using the watch, check its current charge level and charge it if necessary. See "Checking the
Charge Level" (page E-17).
Perform this operation in the Timekeeping Mode (not in the Airplane Mode). See "Mode Reference Guide"
(page E-42).
Perform the GPS position information acquisition operation (page E-30).
Information acquisition successful
You can use the watch as described under
"If you normally plan to use the watch in one
time zone" (page E-11).
Note
If the time and/or date setting is not correct even after you try performing the operations below, use
button and crown operations to confi gure time and date settings manually (page E-63).
− Change to another location and try performing a GPS signal and/or time calibration signal receive
operation again.
− Adjust the hand and day indicator home positions.
Even in the above case, it is recommended that you move to a location that is appropriate for GPS
signal reception and perform a position information receive operation to confi gure time and date
settings.
Even if you are unable to perform a GPS signal and/or time calibration signal receive operation for
some reason, the watch will keep time with average monthly accuracy of ±15 seconds.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp
Under direct sunlight
Important!
Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.
4 o'clock 6 o'clock
Power is low. Charge the watch by placing it in a
location where it is exposed to light.
E-17
Information acquisition failed
Move to a location that is appropriate for
signal reception (page E-29).
Perform the GPS position information
acquisition operation again.
