Using the Crown

The crown is a simple lock type. Before using the crown, first unlock it.

As shown in the illustration, rotating the crown to the u position unlocks it.

As shown in the illustration, rotating the crown to the t position locks it.

Important!

●

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

to push the crown in and lock it

sure when not in use.

●

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

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

after it stops operation due to low

months 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.

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

light by the sleeve of your clothing. Power

the generation efficiency is reduced even when the face of the watch is blocked only partially.

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

●

Checking the Charge Level

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

Important!

●

Should battery go low or go dead, expose

the face (solar panel) to light

as soon as possible.

Immediately after pressing (C) to enter to the Timekeeping Mode, the second hand will

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.

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 the

watch is in the Timekeeping Mode (normal

timekeeping).

●

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

●

This indicates that position information acquisition has started. While acquisition is in progress, the mode hand will move up and down in a semicircular pattern.

●

If position information acquisition is successful, the second hand will move to

“Y(YES)” and then the watch will automatically adjust its time and day settings. The watch will also display the acquired Home City (time zone) and the approximate latitude of your current position.

●

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

move indicate the current time and day without adjusting them.

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.
