INFRARED THERMOMETER LZX-F1682

Introduction

Your new Non-contact Infrared Thermometer uses advanced infrared (IR) technology to measure temperature instantly and accurately on the forehead or object. It is easy to use and requires less measurement time. This thermometer does not need to contact the body or object, ensuring safety and hygiene. Its ergonomic design makes it simple and easy to check temperature, taking only 3 seconds for measurement and reading.

The thermometer features both Body and Object modes. In Object mode, the measuring range is 0.0 to 100.0 °C (32.0 °F ~ 212.0 °F). This allows for measuring body temperature as well as object surface temperatures, such as the surface temperature of milk in a bottle, a baby bath, or the ambient environment temperature.

An alarm sounds when body temperature exceeds 38.5°C. The device includes a memory function that stores up to 1 set of recent measurement data and features an auto power-off function, turning off automatically if left idle for 60 seconds. The measurement time interval is 15 seconds, and the recommended measurement distance is within 5-8 cm. Please read this manual carefully before using the unit and keep it for future reference.

Safety Information

This thermometer is not intended to substitute for a consultation with your physician. The forehead scan temperature serves for reference only and cannot measure fever.

Basic safety precautions should always be observed, especially when the thermometer is used on or near children and disabled persons.

• Please place the device out of reach of children.
• Avoid direct sunlight.
• Do not touch the lens.
• No modification of this device is allowed.
• Keep all packing material safely or dispose of it properly. Swallowing of packing bag, battery, or battery cover may cause suffocation.
• Please do not use any cleaning agent, alcohol, or petrol to clean the unit. Treat it gently and prevent it from falling from a high place.
• Please do not immerse it in liquid.
• Never leave batteries in the battery compartment for a long time without use, as they may leak and cause damage to the unit.
• Please take off the batteries if you do not intend to use the unit within 3 months. Replace with new batteries if the unit displays a low battery symbol [Low Battery Symbol].
• Do not mix old and new batteries together.

To ensure the correct use of the product, basic safety measures should always be followed, including the warning and caution symbols listed in this manual.

Low battery and replacement: During power on, the low battery symbol [Low Battery Symbol] will display. Once the unit starts to work, you should replace with new batteries; otherwise, the unit cannot work.

Battery type and replacement: Please use 2pcs of AAA identical 1.5V alkaline batteries. Do not use batteries beyond their expiry date. Please remove the batteries if you do not need to use the unit for a long time.

WARNING: Dispose the battery in accordance with all federal, state, and local laws. To avoid fire and explosion hazard, do not burn or incinerate the battery.

Setting

How to set:

• Press “SET”, the display will show F-1. Press “+” or “-” to select between °F/°C.
• Press “SET” again, the display will show F-2. Press “+” or “-” to select sound On/Off.

Use of the Unit

Pre-measurement: About Normal Body Temperature & Fever

The temperature in the forehead and temple area differs from the internal temperature, which is taken orally. Vasoconstriction, an effect that constricts blood vessels and cools the skin, can occur during the early stages of a fever. In this case, the temperature measured by the non-contact thermometer may be unusually low. If the measurement therefore does not match the patient's own perception or is unusually low, repeat the measurement every 15 minutes. As a reference, you can also measure the internal body temperature using a conventional oral or rectal thermometer.

Body temperature can vary from one individual to the next. It also varies by location on the body and time of day. Below shows the statistical normal ranges from different sites.

Please keep in mind that temperatures measured from different sites, even at the same time, should not be directly compared. Fever indicates that the body temperature is higher than normal. This symptom may be caused by infection, overdressing, or immunization. Some people may not experience fever even when they are ill.

These include, but are not limited to, infants younger than 3 months old, persons with compromised immune systems, persons taking antibiotics, steroids, or antipyretics (aspirin, ibuprofen, acetaminophen), or persons with certain chronic illnesses. Please consult your physician when you feel feverish even if you do not have fever.

Measuring procedure

As a Body Thermometer

1. Select Body Mode; the temperature unit flashes.
2. Move the probe close to the forehead, make sure the probe is flat, and take measurement with a distance within 5-8 cm. Press the Start/Stop button.
3. The measurement will be finished in 3 seconds. When completed, you can hear a short beep, and the reading will appear on the display.

Note:

• If the reading is ≤ 37.5°C (99.5°F) and ≥ 32°C (89.6°F), the Display will show with green backlight.
• If the reading is ≥ set fever value (≥ 37.5°C and ≤ 38.5°C), the display will show yellow backlight.
• If the reading is ≥ set fever alarm value (≥ 38.5°C and ≤43°C), the display will show together with a long beep, and the red backlight lasts for alarm.
• Only after the unit °C or °F starts to flash again, it can continue to take measurement.
• As the forehead measurement temperature is likely to be affected by sweat, oil, and the surroundings, the reading shall be taken as a reference only.
• If the probe is placed at an angle close to the forehead, the measurement reading will be affected by surrounding temperature.
• Babies' skin reacts very quickly to the ambient temperature. Therefore, do not take their temperature with the non-contact thermometer during/after breast feeding, because the skin temperature may be lower than the internal body temperature.
• The thermometer will automatically turn off if left idle for 60 seconds.

As Object Thermometer

1. Select Object Mode; the temperature unit flashes.
2. Move the probe close to the object, make sure the probe is flat, and take measurement with a distance within 5-8 cm. Press the Start/Stop button to take measurement.
3. The measurement will be finished in 1 second. When completed, you can hear a short beep, and the reading will appear on the display.

Note:

• As the object scan temperature is likely to be affected by the surroundings, the reading shall be taken as a reference only.
• If the probe is placed at an angle close to the object, the reading will be affected by surrounding temperature.
• The thermometer will automatically turn off if left idle for 60 seconds.
