Important!

●

To prevent loss of water

resistance and/or damage due

to impact, be sure to push the

crown in to its normal position

after you are finished using it.

●

When pushing the crown back

in, take care not to apply too

much force.

●

Fast Forward/Fast Reverse

After pulling out the crown, rotating it

quickly in succession in either 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

●

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.

Operation Guide 5412

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 the light by the sleeve of

your clothing. Power generation

efficiency is reduced even when the face

of the watch is blocked only partially.

NOYES

Important!

●

If the second hand stops for

some time after the watch is

continuously exposed to light, it

could mean that charging is not

possible due to over-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.

ー

On the dashboard of a vehicle

parked in the sun

ー

Near an incandescent light

bulb or other source of heat

ー

Under direct sunlight or in

other hot areas for long

periods

Note

●

Exposing the watch face to light

after 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 will

stop approximately 20 days

after the battery goes low.

environment.

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 move to one of the positions below to

indicate the battery charge level.

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.
