Caution!

x The case of the watch may become quite hot when charging. Guard against burn

injury after charging.

x Avoid charging in the following locations, and anywhere else where the watch may

become very hot.

− On the dashboard of an automobile parked in the sun

− Close to an incandescent light source or other sources of heat

− Locations exposed to direct sunlight for long periods

Battery Indicator

While the crown is pushed in, holding down the B button for about one second will

cause the stopwatch second hand to move to a position that indicates the current

battery level (about how long the watch can continue operating).

H : At least four months

M : Two to four months

L : No more than two months

After about two seconds, the hand will return to 12o’clock.

E-5

Solar Charging

A solar panel generates electrical power that charges a built-in (secondary) battery.

The entire face is a solar panel, so power is generated when the face is exposed to

light. Keep the watch exposed to light as much as possible.

Charging the Battery

When you are not wearing the watch, leave it where it is

exposed to light. For stable operation, expose the watch to at

least a half day of light per month.

When wearing the watch, try to keep your clothing from

blocking its face (solar panel). Charging efficiency is reduced

significantly even if the face is blocked only partially.

Crown Operations

Some water-resistant models (100meters, 200meters)

have a screw-in crown. When you need to perform a crown

operation, rotate it towards you to unscrew it. Then pull

the crown out. Avoid applying undue force when pulling.

The watch loses its water resistance while the crown is

unscrewed. After performing a crown operation, fully screw

the crown back in.

What is a quartz movement? Verified

Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.

There is moisture on the inside of the glass of my Casio watch, what should I do? Verified

Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.
