•The above exposure time values are all for reference only. Actual required exposure times depend on lighting conditions.
•The flashing LOW 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 (indicated by M indicator) 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 multiple sensor, illumination, or
|
|
|
| beeper operations during a short period may |
ll |
| lll | cause all of the battery indicators (L, M, H) to | |
l | flash on the display. Illumination, alarm, | |||
l |
|
| l | countdown timer alarm, hourly time signal, and |
l |
|
| ||

sensor operations will be disabled until battery power recovers.
After some time, battery power will recover and battery indicators (L, M, H) will disappear, indicating that the above functions are enabled again.
•Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated by battery indicators (L, M, H) on the display.
•If battery indicators (L, M, H) 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
After a full charge, timekeeping remains enabled for up to about five months.
•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.
Exposure Level (Brightness) | Approximate |
| Exposure Time |
Outdoor Sunlight (50,000 lux) | 5 minutes |
Sunlight Through a Window (10,000 lux) | 24 minutes |
Daylight Through a Window on a Cloudy Day (5,000 lux) | 48 minutes |
Indoor Fluorescent Lighting (500 lux) | 8 hours |
•For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
•Stable operation is promoted by frequent exposure to light.
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.
Moon Phases and Moon Age
The Moon goes through a regular
*The angle to the Moon in relation to the direction at which the Sun is visible from the Earth.
This watch performs a rough calculation of the current Moon age starting from day 0 of the moon age cycle. Since this watch performs calculations
using integer values only (no fractions), the margin for error of the displayed Moon age is ± 1 day.

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 Tide Graph calculates and graphically represents current tide conditions in your Home City or a port city in the vicinity of the Home City based on longitudes, lunar day length, and lunitidal interval preset in watch memory, and on high tide times specified by you.
