Power Levels
Congratulations upon your selection of this CASIO watch.
You can get an idea of the watch’s power level by observing the movement of the
xSecond Hand in the Timekeeping Mode.
If the xSecond Hand is moving normally at one-second intervals, power is at
Level 1.
B
+
This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the
radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.
If the xSecond Hand is moving at two-second intervals, power is at Level 2,
which is quite low. Expose the watch to light as soon as possible so it can
charge.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you
or any third party arising through the use of this product or its malfunction.

When power drops to Level 3, all functions will be disabled but the watch will continue to keep time
internally for about one week. If you recharge the battery sufficiently during this period, the analog hands
will move automatically to the correct setting and normal timekeeping will resume. After one week, all
settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial
factory defaults.

mode.
The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever
power suddenly drops below a certain level due to overuse of the alarm tone over a short period. Note that all
operations are disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal operation after power recovers
(in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover
sooner.

Power Saving
2. Check the Home City and the daylight saving time (DST) setting.
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area
where it is dark. The table below shows how watch functions are affected by Power Saving.
There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Use the procedure under “To configure Home City settings” to configure your Home City and daylight saving
time settings.
Important!
Elapsed Time in Dark
Operation
Proper time calibration signal reception and World Time settings depend on correct Home City, time, and
date settings in the Timekeeping Mode. Make sure you configure these settings correctly.

To set the time manually
The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state
when 6:00 AM arrives, however, it will remain in the sleep state.
The watch will not enter a sleep state while it is in the Stopwatch Mode.
See “Configuring Current Time and Date Settings Manually”.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
The watch is now ready for use.
For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic
Timekeeping”.
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when using
the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as
required. See “Configuring Current Time and Date Settings Manually” for more information.
Charging the Watch
The face of the watch is a solar cell 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.
This section explains how the watch updates its time settings when the city code selected as the Home City is
in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.
Charging Guide
The watch can receive the signal from the transmitter located
Whenever you are not wearing
the watch, 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.
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 if its face is blocked by your
sleeve even only partially.
If your Home City Code setting is this:
here:
LON, PAR, ATH
Anthorn (England), Mainflingen (Germany)
Shangqiu City (China)
HKG
TYO
Fukushima (Japan), Fukuoka/Saga (Japan)
Fort Collins, Colorado (United States)
HNL, ANC, LAX, DEN, CHI, NYC
Important!
Warning!
The areas covered by HNL and ANC are quite far from the calibration signal transmitters, so certain
conditions may cause reception problems.
When HNL or HKG is selected as the Home City, only the time and date are adjusted according to the
time calibration signal. You need to switch manually between standard time and daylight saving time
(DST) if required. See “To toggle the Home City time between standard time and daylight saving time” for
information about how to do this.
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.

Operation Guide 5083 (OC)
Note
Using the Alarm
The Stopwatch Mode can indicate elapsed time up to 23 minutes, 59.99 seconds.
In the following cases, the hands of the watch are moving, so pressing D or B will not perform any
stopwatch operation.
− While the hands are moving to elapsed timekeeping after you enter the Stopwatch Mode
− While the watch is changing dates at midnight
Once started, stopwatch timing continues until you press B to stop it, even if you exit the Stopwatch Mode
to another mode or timing reaches the stopwatch limit defined above.
Whenever you enter the Stopwatch Mode, the hands of the watch move to their initial Stopwatch Mode
positions. If you did not reset the stopwatch the last time you used it, the hands will return to the positions
they were in the last time you exited the Stopwatch Mode.
When the alarm is turned on, an alarm will sound for about 10 seconds each day when the time in the
Timekeeping Mode reaches the preset alarm time. This is true even if the watch is not in the Timekeeping
Mode.

Auto Correction of Hand Home Positions
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 correction of hand home positions correct the hand position
automatically.
For full information on city codes, see the “City Code Table”.
If you think that the time indicated for the selected time zone is not correct, it probably means that there
is something wrong with your Home City settings. Use the procedure under “To configure Home City
settings” to correct the Home City settings.
Auto correction is performed in the Timekeeping Mode only.
Auto correction corrects the positions of the zHour Hand, cMinute Hand, and xSecond Hand. For the
dial hands and day, you must perform the manual adjustment procedure under “Adjusting Home Positions
Manually”.
Each hour, the watch performs automatic correction of the hand positions from –55 minutes to +5 minutes.
You also can trigger auto correction of hand home positions manually, if you want. See “To trigger auto
correction of hand home positions” for more information.
Auto correction of hand home positions 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 auto
correction of hand home positions” or “Adjusting Home Positions Manually”.
To specify standard time or daylight saving time (DST) for a city
1. In the World Time Mode, use D to select the city code whose setting you want
to change.
Wait until the bRight Dial Hands complete their move to the time in the
currently selected World Time City. You will not be able to perform step 2 of
this procedure until the hands stop moving.
2. Hold down A for about two seconds until the watch beeps. This will cause

perform the above operation again.
Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This capability can come in
handy when you frequently travel between two locations in different time zones.
Manually triggered auto correction of hand home positions performs the following
two steps.
The following example shows what happens when the Home City and World Time City are swapped while the
Home City originally is TYO (Tokyo) and the World Time City is NYC (New York).

■ All the watch’s hands are stopped at 12 o’clock and none of the buttons work.
Power may be low. Expose the watch to light until the xSecond Hand starts moving normally, at one-second
intervals.
■ The hands of the watch suddenly start moving at high speed, even when I do not perform any
operation.

The watch may be in the power recovery mode. 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 power
recovers. 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, if necessary.

Time Calibration Signal
The information in this section applies only when LON, PAR, ATH, HNL, ANC, LAX, DEN, CHI, NYC, HKG,
or 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.
Based on data as of December 2008.
The rules governing global times (GMT differential and UTC offset) and summer time are determined by
each individual country.
■ The xSecond Hand indicates NO (N) when I check the result of the latest receive operation.

button operation during the signal receive operation.
The watch is in an area with poor reception conditions.
You are in an area where signal reception is not possible
for some reason.
See “Approximate Reception Ranges”.
Check the website of the organization that maintains the
time calibration signal in your area for information about
its down times.
The calibration signal is not being transmitted for some
reason.
Try again later.
■ The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal, 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.
