- With the thermometer powered OFF, eduki sakatuta Memory (MEM) button gutxi gorabehera 4 segundoz.
- The display will show an icon indicating sound on or off. Release the button when your desired setting is shown.
4. Funtzionamendu-argibideak
4.1 Selecting Measurement Mode
The thermometer supports two measurement modes: Human Body and Object. Use the mode switch located on the side of the device to toggle between these two modes.

Figure 4.1: Illustration of the two measurement modes: Forehead Measurement (Human Body) and Object Measurement (e.g., baby bottle, bath water).
4.2 Neurketa bat egitea
For accurate readings, ensure the measurement distance is between 0 cm and 5 cm. The blue dot focusing system helps identify the optimal distance.

Figure 4.2: The blue dot indicator helps ensure the correct measurement distance (less than 5 cm) for accurate readings.
Neurketa bat hartzeko:
- Ensure the correct mode (Human Body or Object) is selected.
- Point the thermometer sensor towards the center of the forehead (for human body) or the surface of the object.
- Maintain a distance of 0 cm to 5 cm. The blue dot will guide you to the optimal distance.
- Press the measurement trigger. The reading will appear on the LCD screen within 1 second.

Figure 4.3: The thermometer provides quick (1-second) and safe non-contact measurements with fever alerts and memory storage.
4.3 Interpreting Results (Color Backlight)
The LCD display features a three-color backlight to indicate temperature ranges, especially useful for human body temperature:
- Atzeko argi berdea: Indicates a normal temperature (typically below 37.4 °C).
- Atzeko argi horia: Indicates a slightly elevated temperature (typically between 37.5 °C and 38.5 °C).
- Atzeko argi gorria: Indicates a high temperature or fever (typically above 38.6 °C).

Figure 4.4: The display changes color based on temperature: Green for normal, Yellow for slightly elevated, and Red for fever.

Figure 4.5: The bright screen and color alerts ensure clear readings even in low-light conditions, with features like the blue dot indicator and automatic shutdown.
4.4 Memoria berreskuratzea
The thermometer can store up to 99 previous temperature readings. To access the memory:
- Sakatu Memory (MEM) button while the device is on.
- Each press will cycle through the stored readings, from the most recent to the oldest.
5. Mantentzea
5.1 Termometroa garbitzea
To ensure hygiene and accurate readings, clean the thermometer regularly:
- Wipe the thermometer body with a soft, dry cloth.
- For the sensor lens, gently wipe with a cotton swab slightly moistened with alcohol. Do not use abrasive cleaners or immerse the device in water.
- Ensure the sensor is clean and free of dust or debris before each use.
5.2 Biltegiratzea
Store the thermometer in a cool, dry place, away from direct sunlight and extreme temperatures. The recommended storage temperature is -20 °C to 55 °C with humidity ≤ 95 % RH. If not in use for an extended period, remove the batteries to prevent leakage.
5.3 Bateria ordezkatzea
Bateria baxuaren adierazlea pantailan agertzen denean, ordezkatu bi AAA bateriak berriekin. Jarraitu 3.1 ataleko bateria instalatzeko urratsak.
6. Arazoak
If you encounter issues with your thermometer, please refer to the following common problems and solutions:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| Pantailarik ez / Gailua ez da pizten | Bateriak hilda edo gaizki instalatuta. | Ordeztu bateriak beste batzuekin, polaritate zuzena ziurtatuz. |
| Irakurketa okerrak | Incorrect measurement distance; dirty sensor; extreme ambient temperature changes. | Ensure 0-5cm distance using blue dot; clean sensor; allow thermometer to acclimate to room temperature for 30 minutes. |
| Pantailak "Lo" edo "Hi" erakusten du | Temperature is outside the measurement range. | Ensure the temperature is within the specified range (Human Body: 32.0 °C ~ 43.0 °C; Object: 0 °C ~ 100 °C). |
| No sound/Sound not working | Soinu funtzioa desaktibatuta dago. | Refer to Section 3.2.2 to enable the sound function. |
Irtenbide hauek probatu ondoren arazoa konpontzen ez bada, jarri harremanetan bezeroarentzako arreta-zerbitzuarekin.
