Congratulations upon your selection of this CASIO watch.

Note that the product illustrations in this manual are intended for reference only, and so

x

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.

from the calibration signal transmitters, so certain conditions may cause reception

problems.

E-18

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 Day Settings Manually” (page E-39) 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.

E-17

E-15

When power drops to Level 3, all settings (including timekeeping) will be cleared. x

Recharging the battery will reset all settings to their initial factory defaults.

When the watch is at Level 3, exposing it to light for a while will cause the x

x

Second

Hand to move to 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.

E-14

Low Power

Low power conditions are indicated by the movement of

the

x

Second Hand in the Timekeeping Mode.

If the x

x

Second Hand is moving normally at one-second

intervals, power is at Level 1.

If the

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

x

Too close to an incandescent lamp x

Under direct sunlight x

Important!

Keep the watch in an area normally exposed to bright light when storing it for long

x

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

x

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.

Checking the Current Power Level

Certain functions will be disabled when the power level is low. If the power level is

low, leave the watch in a location where its face (solar panel) is exposed to light.

E-12

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

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

x

sleep state (page E-17)

if its face is blocked by

your sleeve even only

partially.

The watch probably is not suffi ciently charged yet. Continue keeping it 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

Sensor

Temperature measurement error occurs.■

This indicates that there is a problem with the sensor or the

watch’s internal circuitry, making sensor measurement and

value correction impossible.

If the error message appears during a measurement,

restart the measurement. If the error message appears

when you restart the measurement, it probably means

that there is a problem with the sensor or internal

circuitry.

E-74

The period when summer time is applied in the location where you are using the x

watch may be different from the period set for your currently selected Home City.

Use the procedure under “To switch between standard time and summer time

manually” (page E-37) to switch from AT (AUTO) to STD (for standard time) or DST

(for summer time).

■ The time and date settings 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 indicator alignment. Adjust the

watch’s hand and day indicator home position alignment (page E-68).

E-73

The time setting is being adjusted following a successful auto time calibration x

signal receive operation (page E-18).

■ Hands suddenly stop moving. Button operation also is disabled.

The watch may be in the power recovery mode (page E-15). 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.

■ The current time setting is off by hours.

Your Home City setting may be wrong. Check your Home City setting and correct it,

x

if necessary (page E-34).

■ The current time setting is off by one hour.

If you are using the watch in an area where time calibration signal reception is x
