 Overview

Intended Use
The non-contact infrared body thermometer is designed to be used for intermittent measurement and monitoring of human body temperature by consumers in the home setting and primary care setting as a screening tool.
Description of Non-Contact Infrared Body Thermometer
Introduction and Operating Principle
This non-contact thermometer is a hand-held, reusable, battery-operated device that measures human body temperature via the patient’s forehead.
The operating principle is based on infrared sensor technology. The infrared sensor can output different signals when measuring different object temperatures or in different ambient temperatures. An application-specific integrated circuit then turns the signal from the infrared sensor into a digital value for display on the LCD screen.

Operation

2.1 Battery Installation
1)Pull the battery cover forward as indicated by the arrow.
2)Insert two AAA-size batteries. Ensure correct polarity as indicated inside the battery cover.
3)Slide the battery cover back in until it snaps in place.

2.2 Before Using the Thermometer
Be sure to read and understand all warnings listed in the instructions before use.

• If the ambient temperature changes too much, such as moving the thermometer from a cold room to a warm room, allow the thermometer to adjust to the new temperature.  This may take up to 30 minutes.
• The ambient temperature around the patient should be stable. Keep away from large air flows such as fans or air-conditioning vents.
• Do not use the thermometer in bright sunlight.
• If a patient moves from a colder environment into a warmer test environment, they should remain in the test environment for at least 5 minutes prior to taking a measurement.  his will ensure the patient is consistent with the ambient temperature.

2.3 Thermometer Self-Test
When the thermometer is off, press the On/Scan button to initiate a self-test. The thermometer will briefly illuminate all segments of the display with green backlighting and then complete a measurement.
2.4 Temperature Modes
The thermometer is capable of measuring body temperature and surface temperature. By default, the thermometer will enter Body Mode when turned on. To toggle between body temperature and surface temperature, press the Mode Button when the device is on.
2.5 Body Temperature
Taking a Body Measurement

• Align the thermometer with the middle of the forehead to measure body temperature (between and above the eyebrows).
• Ensure the distance between the thermometer and the patient’s forehead is between 0.4” and 2.0”  (1cm – 5 cm). See Figure 3.

Figure 3

• Press and release the On/Scan button.
• The measurement will be displayed within two seconds.
• The thermometer will produce an audible indication when the measurement is complete if audio is enabled.
• Wait at least one second before taking the next measurement.
• If a continuous series of measurements are being performed, wait at least 30 seconds after every 5th measurement.

Body Measurement Results

• If the measurement is below 93.2 °F (34.0 °C), the display will show “Lo”, a green backlight, and beep three times if audio is enabled.
• If the measurement is between 93.3 °F and 99.2 °F (34.1 °C and 37.3 °C) the display will show the temperature, a green backlight, a happy face icon, and beep once if audio is enabled. This indicates normal body temperature.
• If the measurement is between 99.3 °F and 100.5 °F (37.4 °C and 38.0 °C), the display will show the temperature, a yellow backlight, a sad face icon and emit a series of beeps if audio is enabled. This indicates a slight fever
• If the measurement is between 100.6 °F and 109.2 °F (38.1 °C and 42.9 °C), the display will show the temperature, a red backlight, a sad face icon and emit a series of beeps if audio is enabled. This indicates a high fever.
• If the measurement is greater than 109.2 °F (42.9 °C), the display will show “Hi”, a green backlight, and beep three times if audio is enabled.

2.6 Surface Temperature
Taking a Surface Measurement

• Ensure the distance between the thermometer and the surface to be measured is between 0.4” and 2.0” (1 cm and 5 cm).
• Press and release the On/Scan button.
• The measurement will be displayed within one second.
• The thermometer will produce a tone when the measurement is complete if audio is enabled. Surface Measurement Results
• If the temperature is less than 32.0 °F (0.0 °C), the display will show “Lo”, a green backlight, and beep three times if audio is enabled.
• If the temperature is between 32.0 °F and 212.0 °F (0.0 °C and 100.0 °C), the display will show the temperature, a green backlight, and beep once if audio is enabled.
• If the temperature is greater than 212.0 °F (100.0 °C), the display will show “Hi”, a green backlight, and beep three times if audio is enabled.
  2.7 Memory Mode

Where p is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters.

Field strengths from fixed RF transmitters, as determined by electromagnetic site surveysª should be less than the compliance level in each frequency rangeª. Interference may occur in the vicinity of equipment marked with the following symbol:

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

a.  Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM, and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the device.
b.  Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
