Operation Guide 2532

• This watch employs a solar cell that converts light into electricity, which charges a

built-in rechargeable battery. Normally, the rechargeable battery should not need

replacement, but after very long use over a number of years, the rechargeable

battery may lose its ability to achieve a full charge. Should you notice problems with

getting the rechargeable battery to a full charge, contact your dealer or CASIO

distributor about having the rechargeable battery replaced.

• The rechargeable battery should be replaced with a CASIO-specified CTL1616

battery only. Other rechargeable batteries can cause damage to 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.

Battery Power Indicator

The battery power indicator on the display shows you the current status of the

rechargeable battery's power.

(Charge Soon Alert)

• The flashing

indicator at Level 4 tells you that battery power is very low, and that

exposure to bright light for charging is required as soon as possible.

• At Level 5, all functions are disabled and settings return to their initial factory

defaults. Functions are enabled once again after the rechargeable battery is

charged, but you need to set the current time, date, and all other settings after the

battery is recharged to Level 3 from Level 5. Though the time appears on the display

after the battery is charged to Level 4, you will not be able to change the time setting

until the battery reaches Level 3.

• Leaving the watch in direct sunlight or some other very strong light source can

cause the battery power indicator to temporarily show a reading that is higher than

the actual battery level. The correct battery power indicator should appear after a

few minutes.

• If you use the backlight or any of the alarm functions a number of times during a

short period, RECOVER appears on the display and the following operations

become disabled until battery power recovers.

Beeper tone

After some time, battery power will recover and RECOVER will disappear, indicating

that the above functions are enabled again.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving

the watch in the areas described below whenever charging its rechargeable battery.

Also note that allowing the watch to become very hot can cause its liquid crystal

display to black out. The appearance of the LCD should become normal again when

the watch returns to a lower temperature.

Warning!

Leaving the watch in bright light to charge its rechargeable battery can cause it

to become quite hot. Take care when handling the watch to avoid burn injury.

The watch can become particularly hot when exposed to the following

conditions for long periods.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

Charging Guide

After a full charge, timekeeping remains enabled for up to about nine months, while

the watch is used under the conditions described below.

Operating Conditions

• Watch is not exposed to light

• Display on 18 hours per day, sleep state 6 hours per day

• 1 backlight operation (1.5 seconds) per day

• 10 seconds of alarm operation per day

• 1 countdown timer operation per day

Charge Times

Exposing the watch to light for the periods shown below each day restores the power

used by the above operating conditions.

Exposure Level (Brightness)

Outdoor Sunlight (50,000 lux)

Sunlight Through a Window (10,000 lux)

(5,000 lux)

Indoor Fluorescent Lighting (500 lux)

• Stable operation is promoted by frequent charging.

Recovery Times

The table below shows the amount exposure that is required to take the battery from

one level to the next.

Reference

This section contains more detailed and technical information about watch operation.

It also contains important precautions and notes about the various features and

functions of this watch.

Power Saving Function

When turned on, the Power Saving function automatically

puts the watch into a sleep state whenever it is left in an

area where it is dark for 30 to 35 minutes. The sleep state

is indicated by a blank screen with SLEEP flashing on it.

In the sleep state, all functions are enabled, except for the

display.

• Wearing watch inside the sleeve of clothing can cause it

to enter the sleep state.

To recover from the sleep state

Perform any one of the following operations.

• Move the watch to a well-lit area. It can take up to five seconds for the display to turn

on.

• Press any button.

• Angle the watch towards your face for reading.

To turn Power Saving on and off

1. In the Timekeeping Mode, hold down A until the

seconds start to flash, which indicates the setting

screen.

2. Press C seven times until the Power Saving on/off

screen appears.

3. Press D to toggle Power Saving on (ON) and off

(OFF).

4. Press A twice to exit the setting screen.

• The Power Saving on indicator (SAVE) is on the display

in all modes while the Power Saving is turned on.

Moon Phase Indicator

The Moon phase indicator of this watch indicates the current phase of the Moon as

shown below.

• The Moon phase indicator shows the Moon as viewed at noon from a position in the

Northern Hemisphere looking south. Note that at times the image shown by the

Moon phase indicator may differ from that of the actual Moon in your area.

• The left-right orientation of the Moon phase is reversed when viewing from the

Southern Hemisphere or from a point near the equator.

Moon Phases and Moon Age

The Moon goes through a regular 29.53-day cycle during which it appears to wax and

wane due to how the Sun illuminates the Moon and the relative positioning of the

Earth, Moon, and Sun. The greater the angular distance between the Moon and the

Sun,

the more we see illuminated.

The angle to the Moon in relation to the direction at which the Sun is visible from the

Earth.

This watch perform a rough calculation of the current Moon age starting from day 0 of

the moon age cycle. The actual Moon age average cycle is 29.53 days, but this can

vary anywhere from –1 day to +1 day for specific months. Since this performs

calculations using integer values only (no fractions), the margin for error of the

displayed Moon age is ±2 days.

Tide Graph

The black bar on the watch's tide graph indicates the current tide.

Low tide

High tide

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 lunitidal interval differs according to your current location, so you must

specify a lunitidal interval in order to obtain the correct tide graph readings.

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."

When setting the lunitidal interval for this watch, use the time differential between the

Moon's transit over the meridian until high tide.

Auto Return Feature

If you leave a screen with flashing digits on the display for two or three minutes without

performing any operation, the watch automatically saves any settings you have made

up to that point and exits the setting screen.

Data and Setting Scrolling

The B and D buttons are used in various modes and setting screens to scroll

through data on the display. In most cases, holding down these buttons during a scroll

operation scrolls through the data at high speed.
