• Do not use the unit to measure any item with a temperature higher than 80.0°C (176.0°F).

General Precautions

• Do not apply a strong shock to, drop, step on, or vibrate the main unit.

• Do not use a mobile phone near the unit.

• The main unit is not waterproof. Be careful when handling this unit so that no liquid (alcohol, water, or hot water) will get into the main unit. When the unit is wet with vapor, wait until it dries or wipe it lightly with a soft dry cloth.

• Do not disassemble, repair, or modify the unit.

• When the probe lens becomes dirty, wipe it lightly with a soft dry cloth or a cotton swab. Do not wipe the probe lens with tissue paper or a paper towel. For details, refer to section 4.3.

• If there is any temperature difference between the places where the unit is stored and where you are going to measure, leave the unit in the room where you are going to use it for more than 30 minutes to allow it to reach room temperature first, then measure.

• If the forehead is cold, wait until the forehead is warmed up before taking a temperature measurement. The measured result may indicate low when you use an ice bag or an ice pack, or immediately after coming in from outdoor in winter.

• Do not use the unit when wet after swimming, bathing, or through sweating after physical exercise, as skin temperature may have fallen. Wipe away moisture and allow 30 minutes for the body to acclimatize to room temperature before measuring.

• Do not touch the probe lens with a finger or breathe on it.

• Do not attempt measurements when the unit is wet as inaccurate readings may result. · Check the icon on the display before and after the measurement so that the measurement is taken in the appropriate
  mode.

• When taking the temperature of an object with low emissivity such as gold or aluminum, inaccurate readings may result.

• When taking the temperature of something with low emissivity (such as milk) in surface measurement mode, slightly lower readings may result.

• Do not use the unit in places where strong static electricity or electromagnetic fields are present. Doing so may lead to inaccurate readings and may contribute to instrument failure.

• When you inform your doctor of your temperature, make sure you state that you measured the temperature from the forehead.

Some Useful Information

How the Forehead Thermometer MC-720 Works
This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point, and then calculates the oral-equivalent value using a unique algorithm based on actual body temperature survey data.

About Body Temperature
Body temperature refers to the stable temperature of the inner body (also known as core body temperature). While temperature measurements at the armpit or mouth provides surface temperature values, holding the thermometer steadily at the measurement point for approx. 10 minutes provides a temperature measurement more closely representing that of core body temperature.
Since forehead temperature measurement involves no bodily support of the thermometer, the resulting measured temperature is typically lower than that of the armpit or mouth.
However, since the forehead has blood vessels that are much less prone to vascular constriction (a natural function of body temperature adjustment), it is supposedly a better measurement area for determining core body temperature, even in a lower temperature environment. By contrast, temperature measured at the arm or leg, for example, is not a suitable gauge of core body temperature, since such body areas are more subject to vascular constriction.
(Note that temperature measured at the forehead may still be influenced by other conditions, such as sweating, or wind from an air conditioner, etc. It is therefore advised to perform measurement in as stable an environment as possible.)

When measuring the temperature of an infant, note that infant body temperature is generally higher than adult body temperature and easily affected by external factors. For example, body temperature tends to increase after nursing or crying. Therefore, it is recommended to take measurements with the infant in calm and normal condition.

Temperature differences between body temperature and forehead temperature

This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point, and then calculates the oral-equivalent value using a unique algorithm (forehead measurement mode) based on actual body temperature survey data.

Knowing One’s Normal Temperature

In order to make a correct judgment of suspected fever conditions, it is important to know one’s normal temperature.
Normal temperature varies with the individual and also changes depending on the time through a day. In addition, measured body temperatures may vary depending on the thermometer or the body part where you measure (see the graph “Variances in core body temperatures obtained at the forehead and mouth”). To find out one’s normal temperature, therefore, we recommend performing regular measurements under the following conditions:
– Measure with the same thermometer.
– Measure at the same area.
– Measure at the same time of day.
