Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read this manual and keep it on hand for later reference when necessary.

Expose the watch to bright light to charge its battery before using it.

You can use this watch even as its battery is being charged by exposure to bright light.

Be sure to read “Battery” of this manual for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank...

If the Power Saving on (S) indicator flashes on the display, it means that the display is blank becausethe watch’s Power Saving function has turned off the display to conserve power. Power Saving automatically turns off the display and puts the watch into a sleep state whenever your watch is left for a certain period where it is dark.

The initial factory default setting is Power Saving on.

The watch recovers from the sleep state if you move it

to a well-litarea*, if you press any button, or if you angle the watch towards your face for reading.

*It can take up to five seconds for the display to turn on.

See “Power Saving function” for more information.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on for about one second, whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto EL Light,” so the auto light switch operates only when available light is below a certain level. It does not turn on the backlight under bright light.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes the backlight to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not surprise or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.

To turn the auto light switch on and off

In the Timekeeping Mode, hold down Bfor about two seconds to toggle the auto light switch on ( displayed) or off ( not displayed).

The auto light switch on indicator ( ) is on the display in all modes while the auto light switch is turned on.

Battery

This watch is equipped with a solar cell and a rechargeable battery (secondary 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.

Example: Orient the watch so its face is

Solar cell

pointing at a light source.

 

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

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

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

This watch employs a solar cell that converts light into electricity, which charges a built-inrechargeable 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-specifiedML2016 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.

The flashing charge (C) 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 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 (indicated by flashing charge (C) indicator), you will not be able to change the time, date, and all other settings until the battery reaches Level 3 (no charge (C) indicator) .

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.

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

Power saving on indicator

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 about one hour in the Timekeeping Mode or Auto Display screen. The sleep state is indicated by a blank screen with Power Saving on (S) indicator 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.

The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

To recover from the sleep state

Perform any one of the following operations.

Move the watch to a well-litarea. 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

In the Timekeeping Mode, hold down D for about two

seconds to toggle Power Saving on (S indicator displayed)

and off (S indicator not displayed).

Note that pressing Dalso toggles between12-hourtimekeeping and24-hourtimekeeping.

Auto Display

Auto Display continually changes the contents of the digital display.

To turn off Auto Display

Press any button (except for B) to turn off Auto Display.

This returns to the Timekeeping Mode.

To turn on Auto Display

Note that Auto Display cannot be performed while a setting screen is on the display.

Auto return features

After you perform any button operation (except for the backlight button) in any mode, pressing Creturns directly to the Timekeeping Mode.

If you leave the watch in the Data Bank, Alarm, and Day Counter Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.

If you leave a screen with flashing digits or a cursor 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, C, 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.

Initial Screens

When you enter the Data Bank, Alarm, or Day Counter Mode, the data you were viewing when you last exited the mode appears first.

Timekeeping

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 to00 without changing the minutes.

The year can be set in the range of 2000 to 2039.

The watch’s built-infull automatic calendar automatically 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 or when battery power drops to Level 5.
