Things to check before using the watch

1. Observe the movement of the

Second Hand.

Is the

Second Hand moving smoothly at one-second intervals?

Is the

Second Hand moving at two-second intervals

or is it stopped completely?

Go to step 2.

The watch is charged. For details about

charging, see “Charging the Watch”

(page E-9).

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).

YES

2. Check the Home City.

Use the procedure under “To conﬁ gure Home City settings” (page E-21) to conﬁ gure your Home City.

Important!

Proper time calibration signal reception depends on correct Home City, time, and date settings. Make

sure you conﬁ gure these settings correctly.

Crown Operations

The crown of this watch is a screw in lock crown. Before using the crown, you

must ﬁ rst rotate it towards you to loosen it.

Important!

x To maintain water resistance and avoid impact damage to the crown, be sure

to screw it back in when you are not using it.

x When pulling out the crown, avoid using undue force, which creates the risk of

personal injury to your ﬁ ngers and ﬁ ngernails, and of watch malfunction.

The illustrations below show the different crown operations.

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.

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.

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

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.

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-25) 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

located here:

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)

Fort Collins, Colorado (United States)

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.

E-12

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)

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.

E-11

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.

the Speciﬁ cations (page E-36).

E-10

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

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

the

Second Hand.

x If the

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

at Level 1.

x 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).

Level Hand Movement Function Status

E-9

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.

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-12) if its face is

blocked by your sleeve even

only partially.

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
