About the crown
Some of the operations of this watch are performed by pulling out the crown, while other operations are
performed by pushing the crown in.
x Button operations may become disabled after you perform a crown operation. If this happens, rotate
the crown slightly. This should restore button operations.
A Button Operation
x The A button is designed to protect against accidental pressing. Use a thin pointed
object to press the depression of the button to operate it.
x In the illustrations in this manual, the A button is emphasized for ease of
understanding.
Congratulations upon your selection of this CASIO watch.
x Note that the product illustrations in this manual are intended for reference only, and so the actual
product may appear somewhat different than depicted by an illustration.
x The module number is engraved on the back cover of the watch case.
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 your watch or its malfunction.
Things to check before using the watch
1. Observe the movement of the 2 Second Hand.
Is the 2 Second Hand moving smoothly at one-second intervals?
ENGLISH
Is the 2 Second Hand moving at two-second intervals
or is it stopped completely?
Power is low. Charge the watch by placing it in a
location where it is exposed to light. For details, see
“Charging the Watch” (page E-7).

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
x Too close to an incandescent lamp
x Under direct sunlight
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
x Best charging
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.
x The watch may enter a sleep
state (page E-10) if its face is
blocked by your sleeve even
only partially.

Important!
x 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.
x 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 Levels

Moves at two-second
intervals.
x When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the
battery will reset all settings to their initial factory defaults.
E-8
Power Saving
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.
x There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep)
6 or 7 days (function sleep)
x 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.
To recover from the sleep state
Move the watch to a well-lit area or press any button.
You can get an idea of the watch’s power level by observing the movement of
31
the
Second Hand.
x If the 2 Second Hand is moving normally at one-second intervals, power is
at Level 1.
x If the 2 Second 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

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:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainfl ingen (Germany)
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)
NEW YORK (NYC), CHICAGO (CHI),
DENVER (DEN), LOS ANGELES (LAX),
ANCHORAGE (ANC), HONOLULU (HNL)
Important!
x The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
The watch can receive the signal from the transmitter
located here:
Fort Collins, Colorado (United States)

2. What you should do next depends on whether you are using Auto Receive or Manual Receive.
x Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive”
for details.
x Manual Receive: Perform the operation under “To perform manual receive”.
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. When any
receive operation is successful, none of the other receive operations for that day are performed.
x When a calibration time is reached, the watch will perform the receive operation. The receive operation
is not performed if a calibration time is reached while you are confi guring settings.

x Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
− Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
− Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
− Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
− Shangqiu (China) transmitter: 500 kilometers (310 miles)
x As of June 2013, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
x Using this watch in a country covered by a time calibration signal that is different from the countries it
supports may result in incorrect time indication due to local application of summer time, etc.
To get ready for a receive operation
1. Place the watch in a location where signal reception is good.
12 o’clock
or
To perform manual receive
1. Keep B depressed for at least two seconds as the
sequence.
x Moves to YES (or Y for some models) or NO (N) to indicate the last signal reception result, then to
READY (R).

When the 22 Second Hand is
pointed here:
READY (R) Watch is setting up for reception.
WORK (W) Reception is in progress.
YES (Y) Reception was completed successfully.
30
NO (N) Reception failed for some reason.
x If signal reception is unstable, the 22 Second Hand may move between WORK
(W) and READY (R).
x When the receive operation is successful, the watch adjusts the time setting
accordingly, and then resumes regular timekeeping. It does not adjust the
setting if the operation failed.
Note
x To interrupt a receive operation and return to regular timekeeping, press any
30
button.
x Position the watch as shown in the nearby illustration,
with 12 o’clock pointed towards a window. Make sure
there are no metal objects nearby.
x Signal reception normally is better at night.
x The receive operation takes from two to seven minutes,
but in some cases it can take as long as 14 minutes.
Take care that you do not perform any button operation
or move the watch during this time.
