GETTING ACQUAINTED

Congratulations upon your selection of this CASIO watch. To get the most out
of your purchase, be sure to read this manual carefully and keep it on hand
for later reference when necessary.

• The measurement functions built into this watch are not intended for
taking measurements that require professional or industrial precision.
Values produced by this watch should be considered as reasonable
representations only.

• The longitude, lunitidal interval, Moon phase indicator, and tide graph
data that appears on the display of this watch is not intended for
navigation purposes. Always use proper instruments and resources to
obtain data for navigation purposes.

• This watch is not an instrument for calculating low tide and high tide
times. The Tide Graph of this watch is intended to provide a reasonable
approximation of tidal movements only.

THERMO SCANNER MODE

The Thermo Scanner Mode uses a sensor built into the watch to measure the
surface temperature of an object with the touch of a button.

Warning!

• The Thermo Scanner of this watch is not a precision measurement.
Its readings should be regarded as reasonably accurate values only.

• Getting too close to a very hot object creates the risk of burn injury, even
if you do not actually touch the object. Make sure you do not get too close
to hot objects when performing Thermo Scanner measurements.

• Do not rely on Thermo Scanner readings to determine whether or not
a very hot or very cold object is safe to touch.

• Do not use the Thermo Scanner as a clinical thermometer.

• The temperature reading produced by the Thermo Scanner indicates

only the surface temperature, and not the actual temperature of an
object.

• For the example shown in the illustration, the diameter of the area

• You can change the measured temperature value displayed by this watch
between Celsius (°C) and Fahrenheit (°F). See “To change the
temperature units”.

How the Thermo Scanner Measures Temperature

The Thermo Scanner doesn’t actually measure temperature directly. Instead,
it calculates the temperature of an object after detecting how much infrared
radiation is being emitted by the object. All objects emit infrared radiation in
accordance with their temperature, their constituent material, and their
surface properties. The intensity of radiation that an object emits (due to the
material it is made out of and its surface properties) is called its
The Thermo Scanner of this watch calculates temperatures based on the
amount of infrared radiation detected and preset emissivity values.

• Setting the correct emissivity value for the object whose temperature you
are measuring helps to ensure results that are more accurate.

• The initial factory default emissivity setting is 0.95, because this is the most
common emissivity for object we encounter in daily life.

sensor of the watch at the object whose
surface temperature you want to measure.

2. Enter the Thermo Scanner Mode, and then

press D to start temperature measurement.

• Pressing D in the Timekeeping Mode

directly enters the Thermo Scanner Mode
and immediately starts temperature
measurement.

Note

• The area measured by the Thermo Scanner
is roughly equivalent to a circle whose
diameter can be approximated by the
formula: d (diameter) = D × 0.78.

The value of “D” is the distance in centimeters
between the object and the sensor.

• “Thermo Scanner Mode” provides important precautions and other
supplementary information about taking measurements with the Thermo
Scanner.

setting.

setting.

• You can set a value in the range of 0.10 to

1.20 in steps of 0.05.

• Pressing B and D at the same time resets

the emissivity value to its initial default
setting of 0.95.
