Solar cell

The electricity generated by the solar cell of the watch is stored by a rechargeable battery. Leaving or using the watch where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Power Supply

This watch is equipped with a solar cell and a rechargeable battery that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.

Solar cell Example: Orient the watch so its face is pointing at a light source.

• The illustration shows how to position a watch with a resin band.

• Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.

• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

Important!

• 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 rechargeable battery power to run down. Be sure that the watch is exposed to bright light whenever possible.

• This watch uses a rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to charge fully, contact your dealer or

CASIO distributor about having it replaced.

• Never try to remove or replace the watch’s rechargeable battery yourself. Use of the wrong type of battery can damage the watch.

• All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.

• Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Moon Phase indicator

The Moon phase indicator of this watch indicates the current phase of the Moon as shown below. It is based on the view of the left side of the moon at meridian transit from the northern hemisphere of the Earth. If the appearance of the Moon phase indicator is reversed from the actual Moon as viewed from your location, you can use the procedure under “To reverse the displayed Moon phase” to change the indicator.

Tidal Movements

Tides are the periodic rise and fall of the water of oceans, seas, bays, and other bodies of water caused mainly by the gravitational interactions between the Earth,

Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch indicates tidal movement based on the Moon’s transit over a meridian and the lunitidal interval. The Tide Graph calculates and graphically represents current tide conditions in your Home City or a port city in the vicinity of the Home City based on longitudes, lunar day length, and lunitidal interval preset in watch memory, and on high tide times specified by you.

Tide Graph

The Tide Graph graphically represents the current tide condition using one of three patterns that represent spring tide, intermediate tide, and neap tide, as shown below.

Tide Name

Spring Tide

Intermediate Tide

Graph Description

Large difference between high tide and low tide. Occurs a few days before and after a New Moon and Full

Moon.

Medium difference between high tide and low tide.

Neap Tide Small difference between high tide and low tide. Occurs a few days before and after the first quarter and last quarter of a half moon.

• The Tide Graph flashes as shown below to indicate the tide range.

lll

llllll

llll

High tide Low tide

• The segments on either end of the Tide Graph flash during high tide.

Lunitidal Interval

Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about six hours later. Actual high tide occurs somewhat later, due to factors such as viscosity, friction, and underwater topography. Both the time differential between the

Moon’s transit over the meridian until high tide and the time differential between the

Moon’s transit over the meridian until low tide are known as the “lunitidal interval”.

• Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

• The year can be set in the range of 2000 to 2099.

• The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.

• The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Coordinated Universal Time (UTC) for each city, based on your Home City time setting.

World Time

• The seconds count of the World Time is synchronized with the seconds count of the

Timekeeping Mode.
