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.

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.

AButton Operation

x The Abutton 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 Abutton is emphasized for ease of understanding.

Things to check before using the watch

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.

possible.

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

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.

Moves at two-second intervals.

You can get an idea of the watch’s power level by observing the movement of the 2 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 charge (Low battery alert).

	3	2 Second Hand stopped.	All functions disabled
		1 Hour Hand and 3 Minute Hand stopped at
		12 o’clock.

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.

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.

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)	2 Second Hand only stopped at 12 o’clock, all other functions enabled
	6 or 7 days (function sleep)	x All functions, including timekeeping, disabled
		x Internal timekeeping maintained

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.

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” (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:	The watch can receive the signal from the transmitter

	NEW YORK (NYC), CHICAGO (CHI),
	DENVER (DEN), LOS ANGELES (LAX),	Fort Collins, Colorado (United States)
	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.

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.

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.

E-12	E-13

x Signal reception may be difficult or even impossible under the conditions described below.

To perform manual receive

1.Keep Bdepressed for at least two seconds as the 2 Second Hand goes through the following

sequence.

x Moves to YES (or Y for some models) or NO (N) to indicate the last signal reception result, then to

READY (R).

2.The 2 Second Hand indicates the operations the watch is currently performing.

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 five 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 configuring settings.
