How to Use the Beurer FT 58 Ear Thermometer

Initial Setup: Insert the two AAA batteries included with your Beurer Ear Thermometer FT 58. To set the time and date, press the start button and use the controls to adjust hours and minutes. To change between Celsius and Fahrenheit, press and hold the start button for 3 seconds on the powered-off device, then use the start button to select your preferred temperature unit.
Taking a Temperature Reading: Before each measurement, place a clean protective cap onto the device. Once powered on, three acoustic signals will sound and the display illuminates. Gently pull the ear slightly upward and backward, then carefully insert the sensor tip into the ear canal. Press the start button to begin measurement. A beep signals the end of measurement. The Beurer FT 58 infrared ear thermometer will display the temperature result with corresponding audio signals indicating the temperature range.
Interpreting Results: A single short acoustic signal indicates temperature under 38°C with a smiling smiley face displayed. Two short signals (temperature between 37.5-37.9°C) serve as a warning for rising temperature. One short signal followed by three longer signals indicates a temperature at or above 38°C with a sad smiley face appearing on the display, triggering the fever alarm.
Switching Measurement Modes: To alternate between body temperature and object temperature mode, briefly press and hold both the on/off button and start button simultaneously. The device automatically switches off after 1 minute of inactivity.
Accessing Memory: To review your last 10 measurements stored in the Beurer Ear Thermometer FT 58, press the M/up button for three seconds on the powered-on device, then press the on/off button again to view individual readings.

Initial Use

The batteries are already inserted in new devices. Before first use, remove the protruding plastic insulating strip from the battery compartment. The ear thermometer will then switch on automatically.

Settings

Setting the Time/Date
Before beginning to take measurements, we recommend that you set the current time and date. This will allow you to organise the saved measurements more easily later.

Setting the temperature unit (°C or °F)
You can set the device to display the temperature in degrees Celsius (°C) or degrees Fahrenheit (°F).

Measuring

Check before each use that the lens is intact. If it is damaged, contact your retailer or the service address. Bear in mind that the ear thermometer needs to have been in the room in which the measurement is taken for at least 30 minutes before use.

Measuring Body Temperature

Some people produce different readings in their left and right ear. In order to record temperature changes, always measure a person's temperature in the same ear.
The ear thermometer may be used by children only under adult supervision. Measurement is usually possible over the age of 6 months. In infants under 6 months, the ear canal is still very narrow, so the temperature of the eardrum often cannot be recorded and the result displayed is often too low.
The measurement must not be taken in an ear affected by inflammatory diseases (e.g. discharging pus or secretion), after possible ear injuries (e.g. eardrum damage) or during the healing period after operative procedures. In all of these cases, please consult your doctor.
Use of the ear thermometer on different persons can be inappropriate in the event of certain acute infectious diseases because of the possible spread of germs despite cleaning and disinfection. If you have any doubts, please consult your doctor.
This ear thermometer may only be used with the protective cap in place.
The following circumstances may influence the temperature in the ear: if you have been lying on the ear for an extended period, the ears are covered, the ears are exposed to excessive heat/cold, or after swimming or bathing. In the event of one of these circumstances, wait 20 minutes before performing the measurement.
As ear wax can affect the measurement, you should clean the ear before measuring if necessary.

Fever Indicator

If the measured temperature is < 38 °C (100.4 °F), a laughing smiley appears on the display and a short acoustic signal sounds.
If the measured temperature falls between 37.5 and 37.9 °C, two short acoustic signals will also sound (the indication for "raised temperature").
If the measured temperature is ≥ 38 °C (100.4 °F), a sad smiley appears on the display and a short, a long and three short acoustic signals sound one after the other.

Displaying room temperature
When you switch on the ear thermometer, the room temperature, the date and time appear alternately on the display every 3 seconds.

Displaying Stored Measurements

The ear thermometer automatically stores the last 10 temperature measurements of body and object temperature, respectively (including date and time). To recall the stored measurements, proceed as follows:

Press the ON/OFF button to switch on the ear thermometer.

Press and hold the ON/OFF button for 3 seconds. An M and the last stored measurement appear on the display.

To switch between the individual stored measurements, press the ON/OFF button . With each subsequent pressing of the ON/ OFF button , the memory space number is displayed first, followed by the measurement.

If you would like to proceed with a measurement, press the START button. Press and hold the ON/OFF button for 3 seconds to switch off the ear thermometer.

Cleaning and Storage

Protective caps are only intended for single use.
The sensor tip is the most sensitive part of the ear thermometer. Work carefully when cleaning the sensor tip to avoid causing any damage. Use a clean cloth or cotton bud that can be moistened with disinfectant, alcohol or warm water.
To clean the entire device, use a soft cloth slightly moistened with a mild soapy solution.
Do not use any harsh cleaning products.
If prolonged storage is intended, you should remove the batteries.
The device must not be stored or used at an excessively high or low temperature or humidity (see technical data), in sunlight, in association with an electrical current or in dusty locations. Otherwise, inaccuracies can occur.
