Congratulations upon your selection of this CASIO watch.

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.

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.

Crown Operations

ENGLISH

The crown can be pulled out to one of two (click) positions. Never apply undue force when pulling out the crown.

Important!

In order to ensure full water resistance and to prevent damage due to impact, make sure that the crown is normally pushed in fully when using the watch. When pulling out the crown, avoid using undue force, which creates the risk of personal injury to your x ﬁ ngers and ﬁ ngernails, and of watch malfunction.

High-speed Movement

When setting a time or when performing home position adjustment (page E-37), you can move the hands either forward or back at high speed. There are two high-speed levels: HS1 and HS2 (faster than HS1).

E-1

E-3

To start HS1 high-speed movement

While the crown is pulled out, rotate it rapidly three turns away from you (for forward movement) or towards you (for reverse movement). High-speed movement will continue even if you release the crown.

To start HS2 high-speed movement

While HS1 high-speed movement is progress, again rotate the crown rapidly three turns in the same direction as the current HS1 movement (away from you for forward movement or towards you for reverse movement).

To stop high-speed movement

Rotate the crown in the direction that is opposite that of the current high-speed

Important!

Leaving the crown pulled out for more than two minutes (approximately 30 minutes in the case of hand home position adjustment) without performing any operation will automatically cause crown operations to become disabled. If this happens, press the crown back in, pull it out, and then start the operation over again.

movement or press any button.

Things to check before using the watch

1. Observe the movement of the x Second Hand.

Is the x Second Hand moving smoothly at one-second intervals?

Is the x 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-9).

2. Check the Home City.

Use the procedure under “To conﬁ gure Home City settings” (page E-22) to conﬁ gure your Home City.

Important!

Proper time calibration signal reception depends on correct Home City, time, and date settings in the Dual Time Mode. Make sure you conﬁ gure these settings correctly.

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 x 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.

When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the x battery will reset all settings to their initial factory defaults, so you will need to conﬁ gure settings again.

E-10

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

Second Hand.

Second Hand is moving normally at one-second intervals, power is

If the at Level 1. If the

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).

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.

On the dashboard of a car parked in direct sunlight

Too close to an incandescent lamp x Under direct sunlight x

When the watch is at Level 3, exposing it to light for a while will cause the x the position of second 57. This indicates that charging has started.

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.

1 Approximate exposure each day to generate power for normal daily operation. * 2 Approximate exposure to take power up one level. *

The above times are for reference only. Actual times depend on lighting conditions.

For details about the operating time and daily operating conditions, see the “Power Supply” section of x the Speciﬁ cations (page E-44).

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.

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-26) 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 HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration

The areas covered by signal transmitters, so certain conditions may cause reception problems.

Signal reception may not be possible at the distances noted below during certain times of the year or x 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) −

As of June 2012, China does not use Daylight Saving Time (DST). If China does go to the Daylight x Saving Time system in the future, some functions of this watch may no longer operate correctly for the China time zones. 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

Conﬁ rm that the watch is in the Dual Time Mode. If it isn’t, hold down 1. C at least two seconds to enter the Dual Time Mode.

Place the watch in a location where signal reception is good.2.

12 o’clock

The watch can receive the signal from the transmitter located here:

Fort Collins, Colorado (United States)

Position the watch as shown in the nearby illustration, x with 12 o’clock 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 10 minutes, but x in some cases it can take as long as 20 minutes. Take care that you do not perform any button operation or move the watch during this time.
