Congratulations upon your selection of this CASIO watch.
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
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.
x
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp x
Under direct sunlight x
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
Best charging
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch, makes
sure that its face is not blocked
from light by the sleeve of your
clothing.
The watch may enter a sleep
x
state (page E-10) if its face is
blocked by your sleeve even
only partially.

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.

Power Recovery 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 continuous signal reception or other operations 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.

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-23) 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.
If your Home City Code setting is this:

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

Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-18). To return directly to the Timekeeping Mode, hold down B
at least two seconds.
■ The
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.
Power may be low. Expose the watch to light until the
second intervals (page E-8).
■ 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-10).
x
The time setting is being adjusted following a successful auto time calibration signal receive operation x
(page E-11).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-9). 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.

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.
■ The
Second Hand indicates NO (N) when I check the result of the latest receive operation.
Possible Cause Remedy Page
You are wearing or moving the watch, or
x
performing a button operation during the signal
receive operation.
The watch is in an area with poor reception x
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.
■ 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-14), 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-20).

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

Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page
E-20).
■ 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-20).
The period when summer time is applied in the location where you are using the watch may be
x
different from the period set for your currently selected Home City. Use the procedure under “To switch
between standard time and summer time manually” (E-22) to switch from AUTO to STD (for standard
time) or DST (for summer time).
■ The hands and/or day indications 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 alignment. Adjust the watch’s hand and day home position alignment
(page E-29).
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-8). Continue exposing the watch to light
until the
Second Hand starts moving normally (at one-second intervals).
The ■
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.
