Operation - Getting started

Removing / inserting batteries: For correct function, the included 2 batteries 1.5V (LR03,AAA) need to be inserted. When the battery exchange symbol appears in the display after a longer time of usage, the batteries should be replaced soonest. When the battery exchange symbol appears together with «Lo» or nothing at all appears in the display , the batteries need to be replaced immediately.
Removal: Remove the lid of the battery compartment and take out the batteries.
Insertion: Put in two new 1.5V-batteries of type LR03 / AAA. Make sure, the batteries are the right way around (see the diagram in the battery compartment ). Put the battery compartment lid back.

Before use

Acclimatise the thermometer to the temperature of the room: For an accurate reading of a patient's temperature, their body must first acclimatise to the temperature of the room where the measurement will be made. The same applies to the Infrared multifunctional thermometer TM 750. When taken somewhere else, it automatically adjusts itself to the new environment. The thermometer takes a certain amount of time to equalise its own temperature to that of the room. This depends on the difference between the two temperatures and can take more than 30 minutes. Precise readings can only be taken once this process is completed.

Setting the unit of measure, the time and the date:
When the thermometer is used for the first time or after a battery change, the unit of measure, the time and the date must first be set. If you want to return to the setting mode later on, press and hold the SET-button for approx. 5 seconds, when device is switched on. After the self-test (where all the display symbols are shown in succession in the display ) two short beeps can be heard. Now you adjust the unit of measure (°C or °F) with the SET-button . Press the Memory-button to confirm the setting. Use the same procedure (SET-button to adjust a value and Memory-button to confirm) for setting the year, month, day, hour and minute. After the last press on the Memory-button the display shows «OFF» and then the device will switch off automatically.

Information on measuring temperature

• The sensor of the thermometer must be kept clean and intact at all times in order to guarantee that the measurements are accurate.
• Ear wax affects the measuring accuracy. If necessary, clean your ear and the sensor tip of the thermometer before measuring in order to avoid erroneous measurements.
• Before taking a measurement on the forehead, clean the area and remove any dirt, sweat or cosmetics before moving the sensor to the measuring position as otherwise erroneous results could be measured.
• Do not measure your temperature immediately after eating, training or bathing. Wait for half an hour.
• Do not take successive measurements at intervals of less than one minute. If you have to take your temperature at shorter intervals, the results may fluctuate slightly.
• The human body temperature fluctuates within a natural range. There is no such thing as a standard body temperature.
• Measure and record your body temperature on normal days. This will allow you to detect a fever more easily.
• In order to make an accurate measurement in the ear, the sensor must be directed at the eardrum and be inserted far enough into the ear canal.
• Some people will have different readings for the right and left ears. Always measure the same person in the same ear when measuring temperature changes.
• The measurements can also be influenced by your sleeping position. If someone has slept on a particular ear for a considerable period, the temperature will be higher than normal in this ear. In this case, measure in the other ear or wait for a few minutes before measuring.

Measuring the temperature at your forehead

NOTE - Forehead temperatures should only be taken for checking purposes, since the skin temperature at the forehead is easily affected by outside influences, meaning that the measurement can be falsified.

1. Switch on the thermometer by shortly pressing the button for forehead measurement mode. The device performs a self-test and emits two short beeps. Optionally, you now have the possibility to temporarily deactivate the sound output of the device until it is switched off. To do this, briefly press the SET button ; the symbol disappears.
   
2. In order to measure the body temperature on the forehead correctly, the sensor cover needs to be put on the sensor.
3. Place the measuring head with the sensor (and the put on sensor cover) on a temple and press the button for forehead measurement mode. The symbol for forehead measurement mode appears in the display. Slowly move the thermometer smoothly over the forehead (button still pressed down) to the other temple. Release the button for forehead measurement mode.
4. After the temperature has been determined, the device emits a signal tone. The result will be shown in the display.
5. If the measurement result is 38.0°C (100.4°F) or higher, the indicator LED lights up in red (= fever alarm). In all other cases the indicator LED lights up in green.
   
6. The measurement result will automatically be saved. After some seconds without pressing any button the device will switch off automatically.

Measuring the temperature in your ear

1. To measure the temperature in your ear, first remove the sensor cover.
   
2. Switch on the thermometer by shortly pressing the button for ear measurement mode. The device performs a self-test and emits two short beeps. Optionally, you now have the possibility to temporarily deactivate the sound output of the device until it is switched off. To do this, briefly press the SET button ; the symbol disappears.
3. Stretch your ear canal by pulling your ear backwards and upwards and carefully insert the sensor into the ear. For children under the age of 1 year, the sensor should be inserted into the ear canal, while the child is lying flat (e.g. on a bed) with the head slightly turned, so that the ear points upward. Press and hold the button for ear measurement mode for approx. 1 second. The symbol for ear measurement mode appears in the display.
4. Release the button. After the measurement process is complete, you will hear a beep and the body temperature will be displayed in the display.
5. If the measurement result is 38.0°C (100.4°F) or higher, the indicator LED lights up in red (= fever alarm). In all other cases the indicator LED lights up in green.
6. The measurement result will automatically be saved. After some seconds without pressing any button the device will switch off automatically.

Measuring the temperature of an object

1. Switch on the thermometer by shortly pressing button or button . The device performs a self-test and emits two short beeps. Optionally, you now have the possibility to temporarily deactivate the sound output of the device until it is switched off. To do this, briefly press the SET button ; the symbol disappears.
2. Press and hold the set & memory buttons at the same time for at least 3 seconds. The symbol for the surface temperature measurement mode appears in the display .
3. To begin the measurement, point the sensor at the middle of the object (resp. of the liquid) at a distance of approx. 3 cm. Press the button for forehead measurement mode or the button for ear measurement mode . If the object has water, dust or dirt on it, remove this first so that the reading is as accurate as possible.
4. Release the button. After the measurement process is complete, you will hear a beep and the measured temperature will be shown in the display.
5. The measurement result will automatically be saved. Again press and hold the set & memory buttons at the same time for at least 3 seconds to return to body temperature measurement mode. After some seconds without pressing any button the device will switch off automatically.

Recalling stored data

The device can store up to 30 results. You can call up your stored data with a short press of the memory button . Firstly, the memory slot number 1 (the most recently saved value) will appear in the display , together with the temperature reading and the symbol for the measurement mode (ear or forehead measurement mode or surface temperature mode). With a further press of the memory button , you can call up the result stored in memory slot "2". A total of 30 memory slots are available and these will be displayed in order if you continue to press the memory button . If a memory slot is empty, the symbol "- -" will appear next to it in the display.
NOTE - In case all memory slots are used, a new measurement result will be saved by deleting the oldest slot (slot no. 30) automatically.
