Congratulations upon your selection of this CASIO watch.

To ensure that this watch provides you with the years of service for which it is designed, carefully read and follow the instructions in this manual, especially the information under “Operating Precautions” and “User Maintenance”. Be sure to keep all user documentation handy for future reference.

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.

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.

Using the Crown

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

Note

x If you do not perform any operation for more than two minutes after pulling out the

crown, crown operations will become disabled automatically. If this happens, push the crown back in and then pull it out again to re-enable crown operations.

x You can use high-speed hand movement when conﬁ guring time settings in the

Timekeeping Mode, Alarm Mode, Countdown Timer Mode or home position adjustment.

x High-speed hand movement is forward only. There is no high-speed backward

hand movement.

x Button operations become disabled after you perform a crown operation. If this

happens, rotate the crown slightly. This should restore button operations.

2. Check the Home City.

Use the procedure under “To conﬁ gure Home City settings” (page E-38) to conﬁ gure your Home City.

Important!

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

3. Set the current time.

x To set the time using a time calibration signal

See “To get ready for a receive operation” (page E-26).

x To set the time manually

See “Conﬁ guring Current Time and Day Settings Manually” (page E-43).

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.

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

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.

To check the current power level

1. In the Timekeeping Mode, press B. The

M (Medium), or L (Low) to indicate the power level.

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.

H: High

M: Medium

L: Low

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-20) if its face is blocked by your sleeve even only partially.

2. If about one second elapses without any operation being performed, the 2 Second

Hand will then move to the latest time calibration signal receive operation result.

x See “To check the result of the latest receive operation” (page E-31).

3. Press B to return to regular timekeeping.

x The watch will also return to regular timekeeping if you do not perform any

operation for about 10 seconds.

E-16

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.

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

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.

Power Saving

Power Saving enters a sleep state (second hand sleep or function sleep) whenever the watch is left for a certain period in an area where it is dark.

Elapsed Time in Dark Operation

60 to 70 minutes (second hand sleep)

6 or 7 days (function sleep)

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 there.

x 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.

Important!

x The areas covered by HNL (HONOLULU) and ANC (ANCHORAGE) are quite far

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

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-43) 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.

x As of December 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 daylight saving time (summer time), etc.
