Things to check before using the watch

1. Check the battery power level.

Congratulations upon your selection of this CASIO watch.

ENGLISH

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.

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.

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.

Charging Guide

E-12

Important!

x

Allowing the watch to become very hot can cause its liquid crystal display to black
out. The appearance of the LCD should become normal again when the watch
returns to a lower temperature.
Turn on the watch’s Power Saving function (page E-19) and keep it in an area

x

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

x

such a way that it is blocked from exposure to light can cause power to run down.
Expose the watch to bright light whenever possible.

E-14

Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.

Best charging

x

performance is achieved
by exposing the watch
to the strongest light
available.

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

x

sleep state (page E-19) if
its face is blocked by your
sleeve even only partially.

E-70 Troubleshooting

E-76 Specifi cations

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.

The fl ashing x LOW indicator at Level 3 (L) tells you that battery power is very low,
and that exposure to bright light for charging is required as soon as possible.
At Level 5, all functions are disabled and settings return to their initial factory

defaults. Once the battery reaches Level 2 (M) after falling to Level 5, reconfi gure
the current time, date, and other settings.
Display indicators reappear as soon as the battery is charged from Level 5 to

x

Level 2 (M).
Leaving the watch exposed to direct sunlight or some other very strong light

x

source can cause the battery power indicator to show a reading temporarily that
is higher than the actual battery level. The correct battery level should be indicated
after a few minutes.
The current time and all other settings return to their initial factory defaults x
whenever battery power drops to Level 5 and when you have the battery replaced.

Power Recovery Mode

Performing illumination or beeper operations during a short period may cause x
all of the battery power indicators (H, M, and L) to start fl ashing on the display.
This indicates that the watch is in the power recovery mode. Illumination, alarm,
countdown timer alarm, and hourly time signal operations will be disabled until
battery power recovers.
Battery power will recover in about 15 minutes. At this time, the battery power

x

indicators (H, M, L) will stop fl ashing. This indicates that the functions listed above
are enabled again.
If all of the battery power indicators (

x H, M, L) are fl ashing and the CHG (charge)

indicator also is fl ashing, it means the battery level is very low. Expose the watch to
bright light as soon as possible.
Frequent fl ashing of all of the battery power indicators (

x H, M, L) probably means

that remaining battery power is low. Leave the watch in bright light to allow it to
charge.

The above exposure times all are for reference only. Actual exposure times depend x
on lighting conditions.
For details about the operating time and daily operating conditions, see the “Power x
Supply” section of the Specifi cations (page E-78).

Power Saving

When turned on, 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.

For information about enabling and disabling power saving, see “To turn Power

x

Saving on and off”(page E-68).

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
“Confi guring Current Time and Date Settings Manually” (page E-47) for more
information.
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.

Even when the watch is within range of a transmitter, signal reception may be x
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

x

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

Auto Receive

x

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

x

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.
You can use the procedure under “To turn auto receive on and off” (page E-34) to

x

enable or disable auto receive.

E-28

Signal reception normally is better x
at night.
The receive operation takes from two

x

to seven minutes, but in some cases
it can take as long as 14 minutes.

Troubleshooting

Time Setting

See “Radio Controlled Atomic Timekeeping” (page E-21) for information about
adjusting the time setting according to a time calibration signal.

The current time setting is off by hours.■

Your Home City setting may be wrong (page E-42). Check your Home City setting
and correct it, if necessary.

The current time setting is off by one hour.■

If you are using the watch in an area where time calibration signal reception is
possible, see “To confi gure Home City settings” (page E-42).
If you are using in the watch in an area where time calibration signal reception is not
possible, you may need to change your Home City’s standard time/daylight saving
time (DST) setting manually. Use the procedure under “To change the current time
and date settings manually” (page E-47) to change the standard time/daylight
saving time (DST) setting.

E-70

The display shows the ERR indicator 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 the signal receive operation.

The watch is in an area with poor x
reception conditions.

You are in an area where signal
reception is not possible for some
reason.

The calibration signal is not being
transmitted for some reason.

E-72

Auto Receive is not performed or you cannot perform Manual Receive.■

Possible Cause Remedy Page

The watch is not in the Timekeeping
Mode or World Time Mode.

Your Home City setting is wrong.

There is not enough power for signal
reception.

Keep the watch in an area where
reception conditions are good while
the signal receive operation is being
performed.

See “Approximate Reception Ranges”. E-23

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. x

Auto receive is performed only while the
watch is in the Timekeeping Mode or
World Time Mode. Switch to either of
these two modes.

Check your Home City setting and
correct it, if necessary.

Expose the watch to light to charge it. E-12

–

World Time Mode

The time for my World Time City is off in the World Time Mode.■

This could be due to incorrect switching between standard time and daylight saving
time. See “To specify standard time or daylight saving time (DST) for a city” (page
E-52) for more information.

Charging

The watch does not resume operation after I expose it to light.■

This can happen after the power level drops to Level 5 (page E-15). Continue
exposing the watch to light until the battery power indicator shows H or M.

Time Calibration Signal

The information in this section applies only when LIS, LON, MAD, PAR, ROM,
BER, STO, ATH, MOW, HKG, BJS, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
MIA, YTO, NYC, YHZ, YYT, SEL, or TYO is selected at the Home City. You need to

adjust the current time manually when any other city is selected as the Home City.

E-71

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-28), 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-42).

The current time setting is off by one hour.■

Possible Cause Remedy Page

Signal reception on a day for switching
between standard time/daylight saving
time (DST) may have failed for some
reason.

Signal reception is being performed successfully, but the time and/or day ■
is wrong.

Possible Cause Remedy Page

Your Home City setting is wrong.

The DST setting may be incorrect. Change the DST setting to Auto DST. E-42

Perform the operation under “To get
ready for a receive operation”.
The time setting will be adjusted
automatically as soon as signal
reception is successful.

If you are unable to receive the time
calibration signal, change the standard
time/daylight saving time (DST) setting
manually.

Check your Home City setting and
correct it, if necessary.
