PRODUCT DESCRIPTION

Introduction
The Lazle Infrared(IR) Thermometer measures human body temperature by calculating the infrared energy emitted from the eardrum or forehead. Measurements take seconds if the thermometer probe is correctly inserted in the ear canal or towards the forehead. The human normal body temperature is a range that varies with sample measurement sites, as seen in the table. Since temperature results are site-specific, values from different locations should not be compared directly. During medical appointments, the type of thermometer used, results, and sample measurement site should be disclosed to the attending physician.

COMPONENT OUTLINE

The Lazle IR Thermometer consists of a casing, a power/measure button, a temperature sensor, an infrared-measuring element, a microcomputer-controlled circuit, an LCD screen, a backlight, and a buzzer.

OPERATING PRINCIPLE

All organic bodies with temperatures greater than absolute zero (-273k) emit energy in the form of heat. The difference in temperature between the body and its surroundings is determined by the infrared thermometer and displayed as the real body temperature. Thus, the Lazle Infrared Thermometer delivers results by collecting the energy emitted by the body in the form of infrared rays and channeling it into a detector, known as the thermopile. The infrared photons are then converted into heat and, finally, electricity, which is measured and displayed on the LCD screen as the body’s actual temperature.

HOW TO USE THE THERMOMETER

To Avoid Inaccurate Measurements:

1. Temperature measurements should only be taken in closed-air spaces (with no strong winds).
2. Ensure the person to be measured (subject) is completely stable during temperature measurement.
3. If the thermometer is moved to a different space with an ambient temperature different from the last space, it should be allowed to adjust for at least 30 minutes before it is used.
4. If the person to be measured comes from a space different from that of the thermometer, they should be given at least 10 minutes to adapt before taking their temperature.
5. Avoid holding the thermometer for too long as it is highly heat and temperature-sensitive.
6. This thermometer has undergone the necessary clinical tests and is guaranteed safe and accurate when used according to the detailed guidelines.

To Take Forehead Temperature Measurements:
Please install the batteries correctly in the battery slots when using the thermometer for the first time. Single-press the Power/Measure button to turn on the thermometer. Repeatedly tap the Mode button to shuffle between and select “0-6 years, 6-12 years, above 12 years” mode. Direct the probe at the forehead, leaving a gap of 0 -3cm (0 – 1.18 inches). Slightly press the Power/Measure button till the beep(s) is heard. Release the button and check the temperature on the screen.

Note:
Results from the forehead mode are indicative and may fluctuate by up to 1°F (0.5°C) from the actual body temperature. Kindly pay attention to the accuracy-influencing factors detailed in the sections “Temperature Measurement Tips” and “Warnings and Precautions.”

CAUTION
Please ensure the forehead and eyebrow areas are free from dirt, sweat, hair, and grime. Clean these areas properly before every measurement for high accuracy. Always ensure the screen is clean for high visibility. The person to be measured and the thermometer must have been in the same space for at least 30 minutes before the measurement for accuracy.

To Take Ear Temperature

1. Single-press the Power/Measure button to turn on the thermometer.
2. Take off the probe cover to switch to the “ear mode” and carefully fit the probe into the ear canal.
3. Slightly press the Power/Measure button till the beep(s) is heard. Release the button and check the temperature on the screen.

CAUTION

• Please ensure the ear canal is clean and free from ear wax and obstructions, such as earphones and dirt.
• Successive ear temperature measurements should be taken from the same ear, as results from different ears may vary.

Please Note
When inserting the thermometer’s probe, please strictly adhere to the following safety instructions:

1. For persons below 1 year: Pull the ear straight backward.
2. For persons 1 year and above (including adults): Pull the ear up and backward.
3. Do not attempt to force the thermometer or the probe into the ear canal to avoid injury.
4. When using the ear mode on adults, the ear canal should be well-aligned with the probe for proper scanning.
5. Extra precautions should be observed when taking ear temperature measurements on children due to their small ear canals.

After Measurement
Once the measurement is complete, withdraw the thermometer from the forehead or ear canal and interpret (read) the values displayed on the screen.
Previous temperature values can be checked on the memory log by pressing the mode button for 5 seconds.

NOTE:

1. After each measurement, the temperature probe should be properly cleaned with a soft, clean cloth before storing the thermometer in a dry, well-ventilated area.

2. Keep all temperature measurements at least 10 seconds apart.

3. This thermometer is NOT a substitute for physician or pediatrician consultations. Do not self-diagnose or
   self-medicate based on the thermometer results. All medical concerns should be addressed by a certified medical practitioner.

4. This device automatically powers after 13 seconds of inactivity.

To Interpret Temperature Measurements

T represents the measured temperature.
In the Forehead or Ear Mode:

• If 32°C ≤ T ≤ 37.5°C (89.6°F ≤ T ≤ 99.5°F), the LCD screen will reflect a GREEN backlight, and a single long beep will be heard, signifying  NORMAL temperature.
• If 37.6°C ≤ T ≤ 38°C (99.7°F ≤ T ≤ 100.4°F), the ORANGE backlight will come on, and three short beeps will be heard, a warning you may have a LOW FEVER.
• If 38.1°C ≤ T ≤ 42.9°C (100.6°F ≤ T ≤ 109.2°F), the RED backlight will come on, and three short beeps will be heard, a warning you may have a HIGH FEVER.

In the Direct Mode:
If 0°C ≤ T ≤ 100°C (32°F ≤ T ≤ 199.0°F), the WHITE backlight will come on, and a single long beep will be heard.

NOTE: Uninstall the batteries if the thermometer will be inactive for more than 2 months.

TEMPERATURE MEASUREMENT TIPS

1. Knowing the normal (healthy) temperature of the measured body is the only way to accurately detect a fever. Measurements should be taken and recorded twice daily (early morning and late afternoon), and the daily average calculated to obtain the normal equivalent temperature. All temperature evaluations within a set should be taken in the same room/space, as temperature values may vary per location, even when taken from the same body area.

2. A child’s normal body temperature can be as high as 99.9°F (37.7°C ) and as low as 97°F (36.1°C). This thermometer reads 0.5°C (0.9°F ) lower than a digital rectal thermometer.

3. Several external factors may influence ear temperature measurements, including but not limited to when the subject has:

   • Been lying on that ear.
   • Had their ears covered for a while.
   • Been exposed to very hot or very cold temperatures.
   • Recently been swimming or bathing.
     In these instances, the subject should be taken from that situation (if applicable) and allowed to re-adjust for at least 20 minutes before taking their temperature measurement.
     For persons using ear medications, the measurement should be taken from the ear without the medications.

4. Holding the thermometer with the hands for too long before a measurement might warm it up and limit accuracy.

5. The subject and the thermometer should have been in the same steady room condition for at least 30 minutes before the measurement for accuracy.

6. Before using the forehead mode, the forehead and brow areas should be clean and free of dirt, sweat, hair, and FIlth. A 10-minute interval should be kept between cleaning and the measurement since warm or cool clothes can alter the actual temperature value.

7. The probe should be disinfected only with an alcohol swab, and the measurement should be taken no earlier than 5 minutes after cleaning.

8. In the following instances, at least 3-5 measurements should be taken from the same site, and the highest value recorded as the actual resultresult. Measurements taken:

   • On babies below 100 days old.
   • On children under the age of three with immunocompromised systems in whom the presence or absence of fever may be critical.
   • By an inexperienced individual who has consistently gotten inconsistent values.

CARE AND CLEANING

• The thermometer casing and probe should be cleaned with an alcohol swab or a cotton swab moistened with 70% alcohol. Do not use the device until the alcohol is completely dried.
• The Lazle Infrared Thermometer is not waterproof and should be protected against all contact with liquids.
• Never use benzene, thinner, or abrasive agents to clean the thermometer.
• Handle this thermometer with care. Protect the LCD screen from abrasion.
