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
cause all of the battery indicators (
L, M, H
) to
flash on the display. Illumination, alarm,
countdown timer alarm, hourly time signal, and
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.
•
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 29.53-day cycle. During each cycle, the
Moon appears to wax and wane as the relative positioning of the Earth,
Moon, and Sun changes. The greater the angular distance between the Moon
and the Sun,* the more we see illuminated.
* 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.
Moon Phase Indicator
The Moon phase indicator of this watch indicates
the current phase of the Moon as shown below. It
is based on the view of the left side of the moon
at meridian transit from the northern hemisphere
of the Earth. If the appearance of the Moon
phase indicator is reversed from the actual Moon
as viewed from your location, you can use the
procedure under “To reverse the displayed Moon
phase” to change the indicator.

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.
