USERâS GUIDE 2590/2591
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 pointing at a light source. â¢ Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc. â¢ The illustration shows how to position a watch with a resin band. Important! â¢ 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. â¢ 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. â¢ The rechargeable battery should be replaced with a CASIO-specified ML2016 battery only. Other rechargeable batteries can cause damage to the watch. â¢ 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 4 and when you have the battery replaced. â¢ Turn on the watchâs 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 batteryâs power.

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, Alarm Mode, or Dual Time Mode. The sleep state is indicated by a blank screen with Power Saving on (P.SAVE) indicator flashing on it. In the sleep state, all functions are enabled, except for the display. â¢ Wearing watch inside the sleeve of clothing can cause it to enter the sleep state. â¢ 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.

Power Saving on (P.SAVE) indicator
(Charge Soon Alert)
4 All functions, including timekeeping, are disabled.
â¢ The flashing CHARGE 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. â¢ At Level 4, 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 and date after the battery reaches Level 3 (indicated by flashing CHARGE indicator) from Level 4. You will not be able to set any of the other settings until the battery reaches Level 2 (no CHARGE indicator) after dropping to Level 4. â¢ 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. â¢ If you use the backlight or any of the alarm functions a number of times during a short period, the RECOVER indicator appears on the display and the following operations become disabled until battery power recovers. Backlight; Beeper tone After some time, battery power will recover and the RECOVER indicator 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. 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. â¢ On the dashboard of a car parked in direct sunlight â¢ Too close to an incandescent lamp â¢ Under direct sunlight Charging Guide After a full charge, timekeeping remains enabled for up to about 11 months, while the watch is used under the conditions described below. Operating Conditions â¢ Watch is not exposed to light â¢ Display on 18 hours per day, sleep state 6 hours per day â¢ 1 backlight operation (1.5 seconds) per day â¢ 10 seconds of alarm 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) Daylight Through a Window on a Cloudy Day (5,000 lux) Indoor Fluorescent Lighting (500 lux) Approximate Exposure Time 5 minutes 24 minutes 48 minutes 8 hours
Auto return features
If you leave a screen with flashing digits 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 D button is used to scroll through setting screen data on the display. Holding down this button during a scroll operation scrolls through the data at high speed.
â¢ The illumination provided by the backlight may be hard to see when viewed under direct sunlight. â¢ The backlight automatically stops illuminating whenever an alarm sounds. â¢ Frequent use of the backlight shortens the battery life. Auto light switch precautions â¢ Avoid wearing the watch on the inside of your wrist. More than 15 degrees Doing so causes the auto light switch to operate when it too high is not needed, which shortens battery life. If you want to wear the watch on the inside of your wrist, turn off the auto light switch feature. â¢ The backlight may not light if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground. â¢ The backlight turns off in about one second, even if you keep the watch pointed towards your face. â¢ Static electricity or magnetic force can interfere with proper operation of the auto light switch. If the backlight does not light, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. â¢ Under certain conditions, the backlight may not light until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight. â¢ You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
â¢ Stable operation is promoted by frequent charging.
