Alarm Mode: AL

Using the Crown

The watch’s crown is a screw-in (screw lock) type.

To use the crown, you first need to rotate

it towards you (leftwards) to loosen it.

Important!

●

To prevent loss of water resistance and/or damage due to impact, be sure

to push the crown in and lock it

when not in use.

●

When pushing the crown back in, take care not to apply too much force.

After pulling out the crown to the first or second

rotating it quickly in succession in either

click, direction will start a fast forward or fast reverse operation. While a fast forward operation is in progress, quickly rotating the crown in succession again will increase the speed even further.

●

The fast reverse operation speed is fixed and cannot be changed.

●

Stopping Fast Forward/Fast Reverse

Rotate the crown in the direction opposite that of the ongoing operation or press any button.

Note

●

Use the (C) button to navigate between modes.

●

Hold down (C) for at least two seconds to return to the Timekeeping Mode.

●

down (C) for four seconds or longer

Holding will enter or exit the Airplane Mode. The mode hand points to h while the watch is in the Airplane Mode.

l Using the Watch on an Aircraft

If you do not perform any operation for about two minutes after pulling out the crown, crown operations will automatically become disabled. If that happens, push the crown back in and then pull it out again.

Solar Charging

What is solar charging?

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

●

This watch uses a special rechargeable (secondary) battery.

ー

The watch’s battery will not charge if the watch’s temperature is less than approximately -10°C (14°F) or greater than approximately 60°C (140°F).

ー

Over-discharge will occur if the watch is not charged within approximately three months after it stops operation due to low battery power. Charging may not be possible after over-discharge occurs.

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.

Important!

●

If the second hand stops for some time after the watch is continuously exposed to light, it could mean that charging discharge. Request chargeable (secondary) battery replacement by your original retailer or authorized CASIO service center.

●

Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under high-temperature conditions like the ones described below.

Note

●

charging time depends on the

Actual local charging environment.

Checking the Charge Level

The charge level is indicated by watch hand movement. Functions become disabled as battery power goes low.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from the

light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Note

●

Exposing the battery goes dead will cause the second hand to revolve counterclockwise until it stops at second 57. This indicates charging has started.

●

A fully charged watch can operate for approximately seven months without further charging. Watch operation days after the battery goes low.

Signal)

The watch’s time, day, and Home City (time zone) settings can be configured in accordance with a received GPS signal or time calibration signal.

●

GPS signal position information: Used to update Home City (time zone), time, and day settings.

●

GPS signal time information: Used to update time and day settings.

Time Adjustment Using GPS

Appropriate Signal Reception Location

GPS signal reception is possible outdoors where the sky is visible and not blocked by buildings, trees, or other objects.

●

Above right figures indicate a lower battery charge.

●

Dead Battery

All hands are stopped.

Power Saving Function

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the second hand to stop, and the watch will enter Level 1 power saving. If the watch is left in this condition for six or seven days, all hands will stop and the watch will enter Level 2 power saving.

Level 1 :

Basic timekeeping functions are operational.

Level 2 :

Only the day indicator is operational.

●

Before trying to receive GPS signal time information and/or a time calibration signal, first use GPS to acquire position information and configure Home Time (time zone) settings.

●

the watch into the Airplane Mode

Put whenever you are inside an aircraft or in any other area where radio wave reception is prohibited or restricted.

Note

●

Areas where time calibration signal reception is supported are limited. When the watch in an area where time calibration signal reception is not supported, adjust time and day settings based on GPS signals.

Reception Ranges

Note

●

In areas where reception is poor, keep the watch face oriented upwards and do not move the watch.

●

When the watch is set up for auto receive, take care to avoid covering the watch face with the sleeve of your clothing.

●

You may experience GPS signal reception problems in the areas described below.

ー

Where the view of the sky above is narrow

ー

Near trees or buildings

ー

Near a train station, airport, or other congested areas

Note

●

Note that the watch also may enter the power saving state if its face is blocked from light by your sleeve while you are wearing it.

●

The watch will enter power saving from the Timekeeping Mode only.

●

Recovering from Power Saving Operation

Press any button or place the watch in a welllit area to recover from power saving.

Acquiring GPS Position Information Manually

You can use a button operation to acquire GPS position information and adjust your Home

City (time zone), time, and day settings

in accordance with your current location.

Note

●

GPS signal reception requires large amounts of power. Perform it only when necessary.

Getting ready

The receive operation is performed only while

watch is in the Timekeeping Mode (normal

●

Normally the mode hand points to the current day of the week.

l Navigating Between Modes

Move to a location appropriate for signal

reception and orient the watch so its

display is pointed straight up at the sky.

Hold down (B) for at least three seconds.

Release

the button as soon as the second

hand points to “T+P”.

●

The second hand will move in the following sequence:

“Y(YES)” or

“N(NO)” n “T (TIME)” n “T+P”.

●

This indicates that position information acquisition

has started. The mode hand will rotate a number of times while information acquisition is in progress.

Note

●

Reception takes anywhere from about 30 seconds to about two minutes.

●

It can take as long as 13 minutes when leap second information is included.

●

You may experience location information acquisition problems

you are in the vicinity of a time

when zone borderline. The watch’s time and day will not be indicated correctly if the Home City (Time Zone) setting is not right for your location. Perform position information acquisition in a representative city in your time zone or in a location that is well within the time zone. Or you can perform a time information receive operation to adjust time and day settings after configuring Home City (Time Zone) and summer time settings manually.

●

If position information acquisition fails for some reason, the second hand will move

to “N(NO)” and then the watch will indicate the current time and day without adjusting them.

Acquiring GPS Time Information Manually

You can use a button operation on the watch to

receive GPS signal time information. When the receive operation is successful, the watch’s Home City (time zone), day, and time settings will be adjusted accordingly.

Note

●

GPS signal reception requires large amounts of power. Perform it only when necessary.

●

If information acquisition is successful,

second hand will move to “Y(YES)”,

the and then the watch will automatically adjust its time and day settings.

●

If reception fails for some reason, the second hand will move to “N(NO)” and then the watch will indicate the current time and day without adjusting them.

Note

●

Reception takes anywhere from about seven seconds to about one minute.
