Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Keep the watch exposed to bright light

The electricity generated by the solar cell of the watch is stored by a built- in 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 only partially covered.
• 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 being 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.

Battery charges in the light.

Battery discharges in the dark.

• The actual level at which some functions are disabled depends on the watch model.
• Be sure to read “Power Supply” (page E-33) for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank…
If the display of the watch is blank, it means that the watch’s Power Saving function has turned off the display to conserve power.

• See “Power Saving Function” (page E-46) for more information.

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.
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.
• The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 (pages E-36 and E-37) and when you have the battery replaced.
• Turn on the watch’s Power Saving function (page E-46) 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.

To check the current battery level
When the battery level is at Level 1 (HI) or Level 2 (MID), the corresponding battery level indicator (HI or MID, page E-8) will appear only if you press C in the Timekeeping Mode. For other battery levels, the applicable indicator appears automatically.

• The battery level indicator shows the current power level of the rechargeable battery.
  Level| Battery Level Indicator| Function Status
  ---|---|---
  1| | All functions enabled.
  2| | All functions enabled.
  3|

(Charge Soon Alert)

| Key operation tone, alarm, Hourly Time Signal, and illumination disabled.
4| | All hands stop at 12 o’clock. All operations disabled.
5| | All functions, including timekeeping, disabled and initialized.

• The indicator at Level 3 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. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.

• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

• Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.

• Performing illumination, or beeper operations during a short period may cause (recover) to appear on the display.
  After some time, battery power will recover and (recover) will disappear, indicating that the above functions are enabled again.

• If (recover) appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

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
The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.

• For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications (page E-52).
• Stable operation is promoted by frequent exposure to light.

Recovery Times
The table below shows the amount exposure that is required to take the battery from one level to the next.

Exposure Level (Brightness)

| Approximate Exposure Time
---|---
Level 5| Level 4| Level 3| Level 2| Level 1
| |
Outdoor Sunlight (50,000 lux)| 3 hours| 35 hours| 10 hours
Sunlight Through a Window (10,000 lux)| 10 hours| 133 hours| 36 hours
Daylight Through a Window on a Cloudy Day (5,000 lux)| 16 hours| 216 hours| 58 hours
Indoor Fluorescent Lighting (500 lux)| 194 hours| – – – – – – – –| – – – – – – – –

• The above exposure time values are all for reference only. Actual required exposure  times depend on lighting conditions.

Adjusting Home Positions

Strong magnetism or impact can cause the hands of the watch to be off. If this happens, perform the applicable home position adjustment procedures in this section.

• Hand home position adjustment is not required if the analog time and digital time are the same in the Timekeeping Mode.

To adjust home positions

1. In the Timekeeping Mode, hold down A for about five seconds. You can release the button after “H.SET” appears on the display.
   • Though “ADJ” will appear on the display after about two seconds, do not release the button yet. Keep it depressed until “H.SET” appears.

Correct hour and minute hand positions

  * The hour and minute hands should move to 12 o’clock (their home position), and “0:00” will flash on the display.
  * If the hour and minute hands are not at 12 o’clock, use D (+) and B (–) to move them there.
  * Holding down either button will cause the hands to move at high speed. Once started, high-speed hand movement will continue even if you release the button.  

To stop high-speed hand movement, press any button.
High-speed hand movement started with the D (+) button will stop automatically after 12 revolutions of the minute hand. If started with the B (–) button, it will stop after one revolution of the minute hand.

2. After everything is the way you want, press A to return to the Timekeeping Mode.
   • After performing home position adjustment, enter the Timekeeping Mode and check to make sure that the analog hands and the digital display indicate the same time. If they do not, perform home position adjustment again.

• Beeper tone, illumination, and display disabled

• Analog timekeeping stopped at 12 o’clock

• Wearing the 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-lit area.
• Press any button.

Auto Return Features

• If you leave the watch in the Alarm Mode, or with the battery level indicator displayed for two or three minutes without performing any operation, it automatically returns to the Timekeeping Mode.
• If you leave the watch with a flashing setting on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen.

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.

Initial Screens
When you enter the World Time Mode or Alarm 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 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 or when battery power drops to Level 5.
• 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.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically dims if it is lit and an alarm or time up alarm sounds.
• Frequent use of illumination runs down the battery
