5. Operating the device

5.1 Basic information
Fever is a state of increased body temperature

Body temperature:
A “normal” temperature is around 36.5 to 37.0 °C (97.7 – 98.6 °F). The highest temperature will be read in the early evening. The values differ according to where the temperature was taken (mouth, armpit, anus, ear, temple).

Causes:
Fever may result from colds, other illnesses such as respiratory infections, some intestinal infections, hyperthyroidism or the presence of tumours.

Symptoms and diagnoses:
Sweating, shivering or chills are indications of an increased body temperature.

You should contact a doctor:
When fever starts, it may have a negative effect on the body, depending on age, the constitution and the current well-being of the person. The use of the device doesn‘t replace the investigations of the doctor. Please inform about the critical values and consult a doctor if these are exceeded.

5.2 Special things to consider when measuring a fever
Please note that when taking the temperature several times in succession, the results may fluctuate by up to half a degree. Factors which may affect the measured value when measuring at the forehead:

• Thickness of the skin at the forehead
• Sweat on the forehead
• Vasoconstrictive medication
• Skin complaints
• Moisturising cream on the skin

The device must stay in stable ambient (room) temperature for 15 minutes before operating.
Do not hold the thermometer in your hands for longer than necessary. Otherwise, the device will warm up and may read a temperature that is too low when checking for fever.
The device is intended for indoor use, where possible, try to avoid using the thermometer outdoors. External influences, such as the wind and outdoor temperature, may have an impact on the measurement.
The person who is having their temperature taken should avoid any fluctuating ambient temperatures for at least 5 minutes before the measurement. Also avoid any strenuous physical activity or taking a bath for at least 30 minutes before the measurement.

5.3 Measurement at the forehead
Make sure the forehead is dry, clean and free from make-up when taking the temperature. Avoid placing the device on any scarred areas.

1. Press the Standby (ON/MEM) button 7 to switch on the device. The forehead symbol will appear on the LCD display. Two beeps will also be heard as signals.
   The mode now shown in the display is the standard mode after the device is switched on. The device is now operational.

2. Remove the cover 1 from the probe head 4 (see Figure B).

3. Keep the device in the centre of the forehead just above the eyes, about 2 to 3 cm away (see Figure C).

4. Briefly press the SCAN button 2.A long beep is heard and the egg timer symbol starts flashing in the display. As soon as the measurement is complete, this symbol disappears, followed by two short beeps.

5. Read the temperature measured off the LCD display 3.

If an elevated temperature of 37.5 °C (99.5 °F) or more is measured in forehead mode, one long and three short consecutive beeps are heard.
If a potential fever is indicated during the temperature measurement, keep body temperature under continuous observation and if the person’s condition is uncertain, consult a doctor. If you would like to perform a further measurement, this is possible as soon as the egg timer symbol has disappeared.

6. To do so, please repeat steps 3., 4. and 5.

After about 1 minute, if there are no further nmeasurements, the thermometer automatically switches from measuring mode to room temperature mode; this can be seen from the temperature symbol.

5.4 Measuring surface temperatures

The thermometer has a measuring range of -22.0 to 80.0 °C (-7.6 to 176.0 °F) for measuring the temperature of surfaces. This enables you to measure the surface temperature of radiators, cooker hotplates, ovens or similar surfaces, as well as liquids.

Note: Please note that steaming surfaces, such as water, food or milk, for example, may cause the reflective mirror with sensor lens 5 to mist up, resulting in a measurement which may be inaccurate.

Warning! The “Surface temperature” setting cannot be used to measure body temperatures/fevers.

Note: Please note when measuring surfaces that it really is only the temperature of the surface which is determined, not the temperature of what is inside. There may be differences in temperature between the surface and the core, especially when measuring liquids. It may be much higher.
Incorrect conclusions may lead to burns or scalds. Before measuring a liquid, stir it to even out these differences as far as possible and then take the measurement immediately.

1. Press the Standby (ON/MEM) button 7 to switch on the device.

2. Hold down the Standby (ON/ MEM) button 7 and press the SCAN button 2 at the same time until the adjacent symbol appears in the LCD display 3. This activates “Surface measurement” mode which enables you to determine the temperature of surfaces.

9. Guidance and manufacturer’s declaration
9.1 Electromagnetic emissions
The THixyz series is intended for use in the electromagnetic environment specified below. The customer or the user of the THixyz series should assure that it is used in such an environment.

9.2 Electromagnetic immunity

Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.

a. 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 THixyz series is used exceeds the applicable RF compliance level above, the THixyz series should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the THixyz series.

b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Note: UT is the a.c. mains voltage prior to application of the test level.

9.3 Recommended separation distances

between portable and mobile RF communications equipment and the ME equipment or ME system. The THixyz series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the THixyz series can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the THixyz series as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
