Frequently Asked Questions - FT 55 BEURER

How to use the FT 55 ear thermometer?

Turn on the device by pressing the power button. Gently pull the earlobe back and upward, carefully insert the sensor tip into the ear canal and press the SCAN button for 1 second. A long beep indicates the end of the measurement. The temperature is displayed with a green (normal) or red (fever) LED.

What is the difference between measurement modes?

The 'ear thermometer' mode (Ⓙ icon) measures body temperature in the ear. The SCAN mode (⚙ icon) allows measuring surface or liquid temperature. The standby mode (clock icon) displays the ambient temperature.

How to switch between °C and °F?

Turn off the thermometer or put it in standby. Hold down the SCAN button and simultaneously press the power button until the unit changes. The values in memory will be converted.

What to do if the screen displays an error message?

Common errors include: measurement during self-test (wait until the ear symbol stops flashing), ambient temperature out of range (10-40 °C), or low battery (replace it). If the error persists, remove the battery for 1 minute and reinsert it.

How to clean the thermometer?

After each use, clean the sensor tip with a soft cloth or cotton swab moistened with disinfectant, alcohol, or lukewarm water. For the device, use a slightly damp cloth with mild soap. Never immerse the device in water.

When to replace the battery?

Replace the battery (type CR2032) when the battery symbol flashes. Use a pointed object to open the compartment, insert the new battery with the + pole facing up, and close.

Is the thermometer accurate for children?

Yes, from 6 months. In infants under 6 months, the ear canal is too narrow for reliable measurement. For older children, clinical accuracy is 0.22 °C.

Can liquids be measured with this thermometer?

Yes, in SCAN mode. Hold the sensor tip near the liquid (without immersing) or directly on the surface. The measuring range is -22 °C to 80 °C.

How to set the date and time?

Turn on the thermometer, then press the ⚙ button for 5 seconds. Use the SCAN button to set successively the 12/24h mode, hour, minutes, year, month, and day. Confirm each step with the ⚙ button.

What to do in case of doubt about fever?

The thermometer emits an alarm (red LED and beep) for any temperature > 37.5 °C. However, it is recommended to consult a doctor for clinical interpretation, especially in the presence of other symptoms.

2. What you should know about using this thermometer

Before using a forehead thermometer, an ear thermometer or a conventional rod thermometer, the following should be noted: The different thermometers listed above are suitable for measuring body temperature in different parts of the body: forehead thermometer: measurement only on the forehead, ear thermometer: measurement only in the ear, rod thermometer: rectal (in the back passage), axillary (under the arm) or oral measurement (in the mouth).

The temperature varies depending on the part of the body where the measurement is taken. The difference in healthy persons between different parts of the body can be between 0.2–1 °C. The approximate normal temperature ranges are as follows:

• forehead temperature – measured with a forehead thermometer: 35.8 °C to 37.6 °C.
• Ear temperature, measured with an ear thermometer: 36.0 °C to 37.8 °C.
• Rectal temperature, measured with a conventional thermometer: 36.3 °C to 37.8 °C.
• orally measured temperature – measured with a conventional thermometer: 36.0 °C to 37.4 °C.

Beurer-Tip:

Temperatures measured with different thermometers cannot be compared with one another.

You should therefore tell your doctor or bear in mind if you are diagnosing yourself what thermometer you used to take your temperature and in what part of the body.

The temperature of a healthy person is also influenced by the following factors:

• The person's individual metabolism.
• Age (body temperature is higher in babies and small children and falls with increasing age. Greater temperature fluctuations occur faster and more often in children).
• Clothing.
  • The outside temperature.
• The time of day (body temperature is lower in the morning and increases during the day towards evening).
• Preceding physical and, to a lesser extent, mental activity.

Beurer-Tip:

Taking the temperature gives a measurement that provides information about a person's current body temperature. If you are uncertain about interpreting the results or if the result is abnormal (e.g. fever), you should consult your doctor. This also applies in the case of slight temperature changes if there are other symptoms of illness such as agitation, severe sweating, flushed skin, fast pulse rate, tendency to collapse etc.

4. Functions

This infrared thermometer measures the

- Temperature in the human ear,

– surface temperature of objects and liquids,

- ambient temperatures.

The thermometer also offers additional functionalities:

• 9 memory locations for simple plotting of changes in temper ature,
  – date and time, also with all stored temperatures measured,
• Optical and acoustic fever alarm at temperatures over 37.5 °C,
• switchable to °C and °F.

5. Operation

This thermometer is designed for use in the ear (ear passage / eardrum) usually for persons aged over 6 months. In children under 6 months, the ear passage is still very narrow so that the temperature of the eardrum can often not be recorded and and the measurement result displayed is too low.

Before taking the temperature, remove the protective cap and ensure that the sensor tip and also the ear passage are clean. If there are signs of acute inflammation (discharge of pus or secretion, pain), in the case of injuries or directly after operations on the ear, the non-affected side should be chosen. Otherwise, the measurement result can be incorrect.

Use of the thermometer in different persons can be inappropriate in certain acute infectious diseases because of the possible spread of germs despite cleaning and disinfection. Discuss this with your doctor in the individual case.

It must only be used without disposable covers.

There is a battery in it already so that it can be used immediately when operated for the first time.

Switch on the thermometer with the “⏻” button. After a brief self-test and two short beeps, the thermo meter is ready to measure the temperature in your ear.

5.1 Setting time and date

With the thermometer switched on, hold the “💡” button depressed for 5 seconds. As soon as the “SET” symbol appears in the display, you can use the “SCAN” button to set in turn the 12 or 24 hour mode, hour, minute, year, month and day ( ,24' appears in the display for the 24-hour mode). Confirm the values set in each case with the “💡” button.

5.2 Batteries

The Type 3V CR2032 battery is already fitted and depending on usage has a life of around 3000 measurements. When the battery gets weak, the battery warning symbol appears ☐. It is still possible to measure the temperature. Battery must be replaced. When the battery symbol fl ashes ☐, the battery must be exchanged by sliding the battery compartment cover off to the rear.

Switch off the device, press the battery compartment lock with a sharp object and slide the battery compartment cover downwards at the same time.

Insert a new battery of the same type with the positive pole at the top. Close the battery compartment cover again.

Used batteries should not go into domestic refuse. You are legally obliged to dispose of the batteries correctly. Dispose of them through your electrical dealer or local recycling centre.

Note: you will find these symbols on batteries containing toxic substances: Pb = battery contains lead, Cd = battery contains cadmium, Hg = battery contains mercury. The battery in this device does not contain toxic substances.

6. During use

Always ensure that the sensor is clean and undamaged. Switch on the thermometer with the "☐" button.

6.1 Measuring in the ear

After a brief self-test and two short beeps, the thermometer is ready to measure the temperature in your ear. The infrared thermometer is in „ear thermometer“ mode. This is indicated by the symbol ⚙.

As the ear passage is slightly curved, you have to pull the ear slightly up and backwards before inserting the sensor tip. This is particularly important so that the sensor tip can be pointed directly at the eardrum. Insert the sensor tip carefully and press the "SCAN" button for 1 sec.

The end of the measuring time is signalled with a long beep. Release the "SCAN" button. You can now read off the temperature measured. The LED is also illuminated according to the test result: a green LED indicates that body temperature is within the normal range, but a red LED lights up with measured values over 37.5 °C, i.e. it is a fever alarm.

The thermometer signals with two short beeps and the cessation of fl ashing of the ear symbol “?” that the unit is ready to continue measurement.

6.2 Saving the temperatures measured

The temperature last measured, i.e. only the last temperature of a series measured, is saved automatically as soon as the thermometer is switched off. There are 9 memory locations available for this.

You can call up the last temperature measured with the “💡” button. The date and time are also shown. The LED does not support any requests for stored measured values. If you continue to hold down the “💡”, you will enter a special measuring mode, in which the thermometer will not make a correct measurement. In this event, allow the thermometer to switch off automatically after about 1 minute and then switch it on again.

6.3 Surface temperatures

When you want to measure surface temperatures with this infrared thermometer, you must change to the "SCAN" mode. With the thermometer switched on (Ear thermometer mode) keep the "☐" button depressed and at the same time press the "SCAN" button. This mode is indicated with the 🔊 symbol. If you keep the "SCAN" button depressed, the surface temperature measured is continuously displayed. You can apply the sensor tip directly to the surface to be measured or measure at close range (do not immerse in liquids).

Note that the displayed temperature is the measured and not the adapted ear surface temperature. It is not the same as the ear temperature.

6.4 Ambient temperature

After the measurement, the thermometer automatically switches to standby mode after about 1 minute, but only if the time has been set. This mode is identified by the 🔔 symbol and the ambient temperature is shown continuously. If you want to use the thermometer to measure the ambient temperature, it should be positioned so that the measurement is not influenced by solar radiation or other influences such as cold draughts from air-conditioning systems. In addition to the ambient temperature, which is updated once every minute, the date and time are displayed alternately.

6.5 Changing the temperature unit

You can display the temperature in degrees Celsius (°C) or degrees Fahrenheit (°F). With the thermo meter switched off or in standby mode, select the unit by holding down the "SCAN" button and at the same time pressing the "☐" button. Keep the two buttons depressed until the temperature unit changes. All stored temperatures are displayed in the new temperature unit.
