Ear Thermometer Advantages
Infrared Ear Thermometer measures core body temperature, which is the temperature of a body’s vital organs. (See Figure 1) Ear temperatures accurately reflect core body temperatures since eardrum is in the cranial cavity and is not affected by the environment. The eardrum shares blood supply with the hypothalamus (part of the brain.) Therefore, body temperature changes are reflected sooner in the ear than they are in other parts of the body.
Ear Thermometer Advantages
Clinical studies have shown that the ear is an excellent site for temperature
measurement because temperatures taken in the ear , reflect the body s core
temperature. Body temperature is regulated by the hypothalamus, which shares
the same blood supply as the tympanic membrane. Changes in core body
temperature are usually seen sooner at the tympanic membrane than at other
sites, such as the rectum, mouth or under the arm.
Advantages of taking temperatures at the ear versus other sites:
- Axillary temperature readings only reflect skin temperature which may not indicate the internal body temperature.
- Rectal temperatures often lag significantly behind internal body temperature changes, especially at times of rapidly changing temperatures.
- Oral temperatures are often influenced by eating, drinking, thermometer placement, breathing through the mouth, or the inability of the person to close their mouth completely.
Body Temperature
The temperature of a healthy person is affected by various factors: the
person’s individual metabolism, their age(body temperature is higher in babies
and toddlers and decreases with age. Greater temperature fluctuations occur
faster and more often in children, e.g. due to growth spurts), their clothing,
the ambient temperature, the time of day(body temperature is lower in the
morning and increases throughout the day towards evening), the preceding
physical and, to a lesser extent, mental activity.
It is suggested that users develop the habit of daily measurement, and use
this product to establish a private normal temperature range for themselves
and their families as a reference for measurement.

-
The right ear reading may differ from the reading taken at the left ear. Therefore, always take the temperature in the same ear.
-
The ear must be free from obstructions or excess earwax buildup to take an accurate reading.
-
External factors may influence ear temperatures such as:
lying on one ear or the other their ears covered
exposed to very hot or very cold temperatures
recently swimming or bathing
In these cases, remove the individual from the situation and wait 20 minutes prior to taking a temperature. -
For persons wearing hearing aids or earplugs, remove the device and wait 20 minutes prior to taking a temperature.
-
When using the thermometer on infants under age 1, pull the ear up making sure the sensor faces the eardrum. (See Figure 5)
-
When using the thermometer on individuals over the age of 1, pull the ear back making sure the sensor faces the eardrum. (See Figure 6)
-

Care And Cleaning
-
Probe covers are intended for single use only! Absent, damaged, perforated, or soiled probe covers can lead to inaccurate temperature readings.
-
The probe window must be kept clean, dry, and undamaged at all times to ensure accurate readings. The accuracy of temperature readings can be affected by damage to the probe window, or the presence of dirt and ear wax on the probe window.
-
Fingerprints, earwax, dust, and other soiling compounds reduce the transparency of the window and result in lower temperature readings. If the thermometer is accidentally placed in the ear without a probe cover installed, the window must be cleaned immediately.
-
The probe window is the most delicate part of the thermometer. To safely clean the window, gently wipe its surface with a cotton swab slightly moistened with isopropyl alcohol and immediately wipe dry with a clean cotton swab. After cleaning, allow at least
5 minutes drying time before taking temperatures.
Note: Do not use any chemical other than isopropyl alcohol to clean the probe window. -

Interference may occur in the vicinity of equipment marked with the following
symbol:
Table 3 continued
NOTE!At 80 MHz and 800 MHz, the higher frequency range applies.NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
a The ISM(industrial, scientific and medical) bands between 0,15 MHz and 80
MHz are 6,765 MHzto6,795 MHz;13,553 MHz to 13,567 MHZ;26,957 MHz to 27,283
MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and

MHz to 54,0 MHZ.
b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz
and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the
likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this
reason, an additional factor of 10/3 has been incorporated into the formulae
used in calculating the recommended separation distance for transmitters in
these frequency ranges.
c Field strengths from fixed transmitters, such as base stations for
radio(cellular/ cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the device is used exceeds
the applicable RF compliance level above, the device should be observed to
verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the device.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the device
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and the device as recommended below, according to the maximum
output power of the communications equipment.
