Battery Installation

Low battery warning:
When the battery power becomes low, the low battery symbol “ ” will appear on the display. The thermometer can still be used during this time, but the batteries should be replaced as soon as possible. If the batteries run out completely, “Lo” will be displayed along with the low battery symbol “ ”. In this case, the batteries will need to be replaced before using the thermometer again.
CAUTION:
Risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
Replacing the Battery:

1. Gently slide the battery cover back.
2. Carefully remove the old batteries and properly discard them.
3. Insert new batteries (Two 1.5V alkalines AAA(LR03) Size) according to the proper polarity.
4. Slide the battery cover back on.

NOTE: Battery-operated

1. Please properly dispose of the batteries away from small children and heat them.
2. It is recommended to remove the batteries if the unit will not be used for an extended period of time.
3. Batteries must be disposed of in accordance with local environmental and institutional policies.
4. Dispose of used batteries in accordance with the applicable legal regulations. Never dispose of batteries in the normal household waste.

Switching Between Fahrenheit or Celsius

Your thermometer can display results in either degrees Celsius (°C) or degrees Fahrenheit (°F). With a combination of Memory and Mode button are able to change the mode to either °C or °F with a beep sound.

Switching between 4 Kinds of Measuring Mode

1. Under power-on status, you can press the Mode Button to switch different measuring modes. There are 4 kinds of modes which include Human, Object, Human/Night, and Object/Night Mode (in order).
2. The beep sounds will be off (mute) when your choice in Human/Night Mode, and Object/Night Mode, and the Moon symbol “ ” will appear on the LCD in both Night Modes.

NOTE:
Each press will come with a beep sound to ensure the setting is activated. (Except both Night Modes)

Tips for Measuring Human Temperature

Bear in mind that the thermometer needs to have been in the room in which the measurement is taken for at least 30 minutes before use.

NOTE:

• Attempting to take temperature readings from sites on the body other than the forehead may produce inaccurate results.
• The patient should remain still while the reading is being taken.
• Readings taken while asleep should not be compared directly to readings taken while awake, as body temperature while asleep is typically lower.
• Do not take body temperature readings within 30 minutes of being outdoors, exercising or bathing.

Measuring Human Temperature

Taking a Measurement

1. Press the Power Button to power on the thermometer. The unit will run a self-test and the LCD will briefly display all of its symbols during this time. When the device is ready, “–“appears on the screen, and the thermometer is ready to take a measurement.

2. Select the desired mode by pressing and releasing the Human/Object Button.
   Note:
   – When taking a patient’s temperature, ensure that the thermometer is in Human Mode; the Human symbol “ ”will appear on the display.
   – If the patient’s skin is covered with hair, sweat, or dirt, clean the area and wait 10 minutes before taking a measurement.
   – Ensure that the thermometer is held firmly during measurement and that the patient does not move until the measurement is complete.
   Movement can impact the measurement.

3. Position the thermometer under 3cm (around 1 inch) from the center of the patient’s forehead with the sensor aimed between the eyebrows.

4. Press and release the Measure Button.

5. Slowly move the device toward or farther from the forehead until you have reached the correct distance. (If the distance is beyond the correct distance, the dash-icon on the display flashes in this sequence until the correct distance is achieved.) Note:
   When the user presses the Measure Button, this workflow begins and they require time for the device to capture the temperature. After capturing the temperature, the display turns to standby mode.

6. As you hear a short beep means this temperature reading has been completed and accompanied by a back-light.

7. If the temperature measurement is below 38°C, a “Smiling Face” will appear next to the reading. If the reading is 38°C or above, a “Frowning Face” will display and the LED light up to alert.

8. After about 60 seconds after use, the thermometer will automatically beep and shut off.

Fever Alarm:
Only in Human Mode and Human/Night Mode.

Measuring Object/Liquid Temperature

1. Press the “Measure Button” to turn the thermometer on. All symbols on the display will momentarily appear.
2. Ensure that the thermometer is in Object Mode; the Object symbol “ ”will be on the display. To alternate between modes press and release the Human/Object Mode Button until you see the desired measurement symbol on the display.
3. Position the thermometer under 3cm (around 1 inch) from the object.
4. Release the “Measure Button” and the temperature reading will be displayed.
5. After use, the thermometer will automatically beep and shut off after idling.

Memory Function

Memory Recall:
You can recall up to 10 measurements currently stored in memory to share with your physician or trained healthcare professional.

1. When the device is on, press once briefly on the Memory Button, then pass it again to show the last measurement accompanied by “ ” symbol.

2. The “ ” symbol or “ ” symbol will appear with each measurement stored in memory to indicate whether a person or
   object temperature was taken.

3. Each press of the same button recalls a previous measurement.

Memory Deletion:

1. Under power-on status, you may hold press the “Memory button” to delete all the readings. The LCD shows “- -” with one beep sound to indicate that all memories are cleared.
2. Remove batteries, memory will be cleared.

NOTE:
All the readings will be cleared no matter record in Human Mode or Object Mode.
