Charging the 5516 Watch MA1611-EA

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.
Charging Guide

Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

casio_5516_watch_ma1611-ea.instructions.png

Best charging performance is achieved by exposing the watch to the strongest light available. When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.
The watch may enter a sleep state (page E-19) if its face is blocked by your sleeve even only partially.

Warning!
Leaving the watch in bright light for charging 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

Important!

Allowing the watch to become very hot can cause the digital displays to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.
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 power to run down. Expose the watch to bright light whenever possible.

Power Levels

You can get an idea of the watch’s power level by observing the battery power indicator in the lower digital dial.

casio_5516_watch_ma1611-ea._battery_power_indicator.png

Level	Battery Power Indicator	Function Status
1 (H)		All functions enabled.
2 (M)		All functions enabled.
3 (L and LOW)		Illumination and beeper disabled. Except for Timekeeping Mode, all other modes disabled.
4 (CHG)		All functions and display indicators disabled except for timekeeping and display of CHG (charge) in the right digital dial. Hour and minute hands stopped at 12 o'clock.
5		All functions disabled.

The flashing LOW message at Level 3 (L) 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 (M) 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 (M).
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.
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.

Using the Stopwatch

The stopwatch measures elapsed time, split times, and two finishes.
To enter the Stopwatch Mode
Use C to select the Stopwatch Mode (STW)

To perform an elapsed time operation

Using the Alarm

You can set five independent daily alarms. When a daily alarm is turned on, an alarm tone will sound for about 10 seconds each day when the time in the Timekeeping Mode reaches the preset alarm time. This is true even if the watch is not in the Timekeeping Mode. You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the hour.

To enter the Alarm Mode
Use C to select the Alarm Mode as shown.

The right digital dial will show ALM for about one second and then the indictor for the currently selected alarm (AL1 through AL5, or SIG) will appear.
When you enter the Alarm Mode, the data you were viewing when you last exited the mode appears first.

To set an alarm time

In the Alarm Mode, use D to scroll through the alarm indicators (AL1 to AL5, SIG) in the right digital dial until the one whose time you want to set is displayed.
Hold down A for about two seconds until the alarm time starts to flash. This is the setting mode.
Whenever you enter the setting mode, the analog hands will automatically move to positions that allow easier viewing of the digital dials.
Press C to move the flashing between the hour and minute settings.
While a setting is flashing, use D (+) and B (–) to change it.
When setting the alarm time using the 12-hour format, take care to set the time correctly as a.m. (no indicator) or p.m. (PM indicator).
Press A to exit the setting mode.
Exiting a setting mode will normally cause the hands to return to regular timekeeping automatically. However, if you manually move the hands and then enter a setting mode, they will not return to regular timekeeping automatically when you exit the setting mode. In this case, you will need to return the hands to their normal positions manually.

Power Recovery Mode

Performing multiple illumination, beeper, and/or high-speed hand movement operation during a short period may cause all of the battery power indicators (H, M, and L) to start flashing in the lower digital dial. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, and hourly time signal operations will be disabled until battery power recovers.
Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will stop flashing. This indicates that the functions listed above are enabled again.
If all of the battery power indicators (H, M, L) are flashing and the CHG (charge) message also is flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
Frequent flashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

6 or 7 days (function sleep)	Blank	Hour and minute hands stop at 12 o’clock. All functions are disabled, but timekeeping is maintained.

When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving
There actually are two sleep state levels: “display sleep” and “function sleep”.
The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.
The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

To recover from the sleep state
Move the watch to a well-lit area or press any button.

Troubleshooting of Casio 5516 Watch MA1611-EA

If you are experiencing any issues with your Casio 5516 Watch MA1611-EA, here are some common problems and solutions:

If the watch is not keeping accurate time, try resetting it to the correct time and date.
If the alarm or timer functions are not working, make sure that they are properly set up and activated.
If the watch is not responding to button presses, try restarting it by removing and reinserting the battery.

Time Setting

The current time setting is off by hours
Your Home City setting may be wrong (page E-26). Check your Home City setting and correct it, if necessary.
The current time setting is off by one hour
You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the procedure under “To change the current time and date settings” (page E-31) to change the standard time/daylight saving time (DST) setting.
The hands are off
This could indicate that the watch has been exposed to magnetism or strong impact, which has caused problems with proper hand alignment. Adjust the watch’s hand home position alignment (page E-57).
The analog hands are not indicating the correct time
If the HANDS indicator is displayed on the right digital dial, it means that the analog hands have moved for easier viewing of the digital dials. Hold down C for about four seconds to return to the Timekeeping Mode.

World Time Mode

The time for my World Time City is off in the World Time Mode
This could be due to incorrect switching between standard time and daylight saving time. See “To specify standard time or daylight saving time (DST) for a city” (page E-37) for more information.

Charging

The watch does not resume operation after I expose it to light
This can happen after the power level drops to Level 5 (page E-15). Continue exposing the watch to light until the battery power indicator shows H or M.
