Operation Guide 5060
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 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.
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.
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 state if its face is
blocked by your sleeve
even only partially.

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.
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 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.
You can get an idea of the watch’s power level by
observing the movement of the
Timekeeping Mode.

The above exposure times all are for reference only. Actual exposure times depend •
on lighting conditions.
For details about the operating time and daily operating conditions, see the “Power •
Supply” section of the Specifications.
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.
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)
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 or •
Countdown Timer Mode.
To recover from the sleep state
Move the watch to a well-lit area or press any button.

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.

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.
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:
LON, PAR, ATH Anthorn (England), Mainflingen (Germany)
HKG Shangqiu City (China)
TYO Fukushima (Japan), Fukuoka/Saga (Japan)
HNL, ANC, LAX, DEN, CHI, NYC Fort Collins, Colorado (United States)
Important!
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.

1,500 kilometers
The Anthorn signal is receivable
within this area.
Japanese Signal
Fukushima
500 kilometers
Fukuoka/Saga
1,000 kilometers
Even when the watch is within range of a transmitter, signal reception may be •
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 influence of the
conditions listed above becomes even greater.
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.
Mainflingen (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)
As of January 2008, 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.
To get ready for a receive operation
Confirm that the watch is in the Timekeeping Mode. If it isn’t, hold down 1. C for
about two seconds to enter the Timekeeping Mode.
Place the watch in a location where signal reception is good.2.
Signal reception may be difficult or even impossible under the conditions •
described below.
The watch can receive the signal from the
transmitter located here:
Mainflingen
Position the watch as shown in the •
nearby illustration, with 12 o’clock

or
pointed towards a window. Make
sure there are no metal objects
nearby.
Signal reception normally is better •
at night.
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.

What you should do next depends on whether you are using Auto Receive or 3.
Manual Receive.
Auto Receive
With Auto Receive, the watch performs the receive operation each day •
automatically up to six times (up to five 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 Timekeeping Mode or World Time Mode. The receive operation is
not performed if a calibration time is reached while you are configuring settings.
To perform manual receive
In the Timekeeping Mode, keep 1. A depressed (for about two seconds) as the
x Second Hand goes through the following sequence.
The 2.
Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can result in the wrong time setting. •
Even if a receive operation is successful, certain conditions can cause the time •
setting to be off by up to one second.
The watch is designed to update the date and day of the week automatically for •
the period January 1, 2000 to December 31, 2099. Updating of the date by signal
reception will no longer be performed starting from January 1, 2100.
If you are in an area where signal reception is not possible, the watch keeps time •
with the precision noted in “Specifications”.
The receive operation is disabled under any of the following conditions. •
While power is at Level 2 or lower −
While the watch is in the power recovery mode −
When the watch is in the function sleep state (power saving) −
While a countdown time operation is in progress −
A receive operation is cancelled if an alarm sounds while it is being performed. •
