The left-right orientation of the Moon phase is reversed when viewing from
BACKLIGHT
the Southern Hemisphere or from a point near the equator.
The Moon phase indicator displayed in the Timekeeping Mode and Alarm
Mode is based on Timekeeping Mode (home site) data. The indicator
displayed in the Site Mode and Moon Data Mode is based on data for the
site that is currently selected in the Site Mode. There is no Moon phase
indicator in the Thermo Scanner Mode.
The backlight uses an EL (electro-luminescent)
panel that causes the entire display to glow for
easy reading in the dark. The watch’s auto light
switch automatically turns on the backlight
when you angle the watch towards your face.
•
The auto light switch must be turned on
(indicated by the auto light switch on
indicator) for it to operate.
See “Backlight Precautions” for other
important information about using the
backlight.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle during which it appears to
wax and wane due to how the Sun illuminates the Moon and the relative
positioning of the Earth, Moon, and Sun. The greater the angular distance
between the Moon and the Sun,* the more we see illuminated.
•
Auto light switch on indicator
*
The angle to the Moon in relation to the direction at which the Sun is visible
from the Earth.
Turning on the Backlight Manually
The Moon age indicates the number of days from the New Moon to any
particular phase. It is normally calculated using either noon or midnight as a
reference point. This watch calculates the Moon age based on the angular
distance of the Moon at noon, which can result in an error of 1 day. Because
of this, the appearance of the Moon phase indicator may be different from
that of the actual Moon.
In any mode, press L to illuminate the display for about two seconds.
•
The above operation turns on the backlight regardless of the current auto
light switch setting.
The watch uses the following formula to calculate Moon age.
Moon Age (days) = 29.53 × (Moon angular distance / 360°)
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about two
seconds, whenever you position your wrist as described below in any mode.
Tide Graph
Moving the watch to a position that is parallel to the ground and then tilting
it towards you more than 40 degrees causes the backlight to light.
The black bar on the watch’s tide graph indicates the current tide.

The tide graph displayed in the Timekeeping Mode and Alarm Mode is
based on Timekeeping Mode (home site) data. The graph displayed in the
Site Mode and Moon Data Mode is based on data for the site that is
currently selected in the Site Mode. There is no tide graph in the Thermo
Scanner Mode.
Warning!
•
Never try to read your watch when mountain climbing or hiking in areas
that are dark or in areas with poor footing. Doing so is dangerous and
can result in serious personal injury.
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 the meridian and the lunitidal interval. The lunitidal interval differs
according to your current location, so you must specify a lunitidal interval in
order to obtain the correct tide graph readings.
•
Never try to read your watch when running where there is danger of
accidents, especially in locations where there might be vehicular or
pedestrian traffic. Doing so is dangerous and can result in serious
personal injury.
Never try to read your watch when riding on a bicycle or when operating
a motorcycle or any other motor vehicle. Doing so is dangerous and can
result in a traffic accident and serious personal injury.
When you are wearing the watch, make sure that its auto light switch
is turned off before riding on a bicycle or operating a motorcycle or
any other motor vehicle. Sudden and unintended operation of the
auto light switch can create a distraction, which can result in a traffic
accident and serious personal injury.
•
•
Lunitidal Interval
Theoretically, high tide is at the Moon’s transit over the meridian and low tide is
about six hours later. Actual high tide occurs somewhat later, due to factors
such as viscosity, friction, and underwater topography. Both the time differential
between the Moon’s transit over the meridian until high tide and the time
differential between the Moon’s transit over the meridian until low tide are
known as the “lunitidal interval.” When setting the lunitidal interval for this
watch, use the time differential between the Moon’s transit over the meridian
until high tide.
To turn the auto light switch on and off

Auto Return Features
•
If you leave a screen with flashing digits or a cursor on the display for two
or three minutes without performing any operation, the watch automatically
saves anything you have input up to that point and exits the setting screen.
If you leave the watch in any mode for about three minutes without
performing any operation, it automatically changes to the Timekeeping
Mode.

Measurement Range
Site Mode
The area measured by the Thermo Scanner increases the further you are
from the object. Make sure you are close enough to the object so the area
measured remains within the surface area of the object.
Also, remember that the temperature value displayed by the watch is the
average temperature for the entire area measured.
•
The current time in all Site Mode sites is calculated in accordance with the
Greenwich Mean Time (GMT) differential for each site, based on the
current time setting in the Timekeeping Mode.
GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
•
Backlight Precautions
•
•
The electro-luminescent panel loses illuminating power after very long use.
The illumination provided by the backlight may be hard to see when viewed
under direct sunlight.
•
•
The watch will emit an audible sound whenever the display is illuminated. It
does not indicate malfunction of the watch.
The backlight automatically turns off whenever an alarm sounds.

Auto light switch precautions
•
Avoid wearing the watch on the inside of your wrist. Doing so causes the
auto light switch to operate when it 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.
Diameter of the area measured can be approximated by the formula:

•
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.
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.
Measurement Time: Approximately 3 seconds
Emissivity
The intensity of infrared radiation that an object emits (due to the material it is
made out of and its surface properties) is called its emissivity. Fixed
emissivity values have been established for a number of objects. Emissivity is
expressed as a value that represents the ratio of the radiation intensity of a
real body to the radiation intensity of a blackbody*, which is 1.
•
•
In order to protect against running down the battery, the auto light switch is
automatically turned off approximately six hours after you turn it on.
*
blackbody: A total absorber that absorbs all the energy that falls upon it.
Generally speaking, the emissivity of human skin, wood, and paper is high,
while that of aluminum, and other metals is low. Metals whose surfaces are
oxidized (non-lustrous finish) tend to have high emissivity, while polished
(lustrous) surfaces tend to have low emissivity.
Thermo Scanner Mode
Measurement Precautions
•
The temperature reading produced by the Thermo Scanner indicates only
the surface temperature and not the actual temperature of the object.
Measuring the temperature of your hand, for example, displays the
temperature of your skin surface, not your body temperature. Note that
surface temperature is affected by surrounding temperature and other
factors.
Note
•
Low emissivity objects (especially those with a lustrous, metallic finish)
tend to reflect infrared radiation emitted by surrounding objects, and so
accurate temperature readings are impossible.
•
For more accurate Thermo Scanner readings from a particular type of
object, measure the temperature of the object using another measurement
device you know to be accurate, and then use the Thermo Scanner to take
a reading of the object. Next, adjust the emissivity value until the reading
produced by the Thermo Scanner is the same as the other instrument.
The “EMISSIVITY VALUES” provides emissivity values for a number of
different objects. Note that these values are for reference purposes only.
Other factors can also affect emissivity.
•
Accurate measurements are not possible for the following types of objects.

Description
Metal objects, objects coated
with shiny paint (gold, silver,
etc.) and other objects with

Air or gas
•
The Thermo Scanner can pick up infrared
radiation from solids and liquids only.
•
•
•
•
•
Take care to keep the sensor lens free of dirt, dust, chemicals, and other
foreign matter. A dirty or damaged lens makes accurate measurement
impossible.
Leaving the watch in a closed automobile under direct sunlight or
otherwise subjecting it to high temperatures can cause the sensor to
overheat, which makes accurate measurement impossible.
Fluctuation of the temperature of the watch itself (due to taking the watch
outdoors on a cold day, etc.) can cause unstable sensor temperature,
making accurate measurement impossible.
Avoid keeping the watch too close for long periods to objects that
continuously generate high heat (like a hot plate), which can cause
overheating of the watch.
Any of the following causes the measurement operation to be cancelled:
changing to another mode, sounding of an alarm or hourly time signal,
turning on the backlight, display of the emissivity value, changing the
emissivity value setting, measurement error.

temperature readings.
To clean the lens
Rinse the lens with cold or warm water and then wipe off
all remaining moisture with a cotton swab, taking care
not to scratch the lens.
The lens may be dirty, even though you cannot see any
dirt or dust on it. Because of this, you should make it a
habit to clean the lens periodically.
Important!
•
Acids (including fruit juices, etc.) can permanently damage the lens and
make accurate measurements impossible. Should any acidic matter get
onto the lens, rinse it off immediately.
•
Accurate measurements are impossible whenever there is condensation,
water droplets, snow, or any other moisture on the lens. Before
measurements, wipe off all moisture with a cotton swab, taking care not to
scratch the lens.
•
Avoid scratches by keeping scissors, needles, and other pointed objects
away from the lens.
