Smart Forehead Thermometer - User Guide
1.1. Introduction
Thank you for choosing the NantLife Smart Forehead Thermometer. This innovative medical device relies
on advanced infrared (IR) technology to measure temperature instantly.
Your new digital thermometer uses the infrared heat generated by patient’s skin. The thermometer then
converts it into a temperature value displayed on the OLED screen.
Note: The thermometer does not emit any infrared signal.
With its unique wireless integrated technology, the NantLife Smart Forehead Thermometer enables you
to perform first-class, comfortable and extremely gentle body temperature measurements. You have
chosen the most up-to-date form of healthcare management. Measured values are transmitted
automatically to a secured database via a Bluetooth-enabled mobile phone and/or the HBoxhub.
Choose between 2 basic configurations:
a) Smart Medical Home with the HBox
b) Mobile Health with your Bluetooth-enabled smartphone
The NantLife Smart Forehead Thermometer comes with the following components:
•Monitor with OLED display

1.4 Before taking a Measurement
General information about normal body temperature and fever.
Body temperature can vary from one individual to the next. It also varies by location on the
body and time of the day. See below the statistical normal ranges for different sites:
Body Site Normal Temperature Range
Oral 35.5°C – 37.5°C 95.9°F – 99.5°F
Axillary (underarm) 34.7°C – 37.3°C 94.5°F – 99.1°F
Rectal 36.6°C – 38.0°C 97.9°F – 100.4°F
Ear 35.8°C – 38.0°C 96.4°F – 100.4°F
Chamberlain, J.M. Terndrup, T.E., New Light on Thermometer Readings,
Contempory Pediatrics, March 1994
Temperatures measured from different sites, even at the same time, should not be
compared.
Fever indicates that the body temperature is higher than normal. This symptom may be
cause by infection, overdressing or immunization. Some people may not experience fever
even if they are ill. These include, but are not limited to, infants under 3 months old, persons
with compromised immune systems, person with chronic diseases, person taking antibiotics,
steroids or antipyretic such as aspirin, ibuprofen and/or acetaminophen.
Please consult your physician when you feel ill even if you do not have fever.
Your healthcare providers want to get an accurate picture of your body temperature and
chart what happens over time. Body temperature is a vital indicator of one's health. A
number of diseases are accompanied by characteristic changes in body temperature.
Likewise, the course of certain diseases can be monitored by measuring body temperature.
The efficiency of many treatments can be evaluated by monitoring body temperature and
changes therein. Fever is a reaction to disease-specific stimuli, where the set point of the
temperature control center is varied to promote the body's defenses against the disease
process. Fever is the most common form of pathological (disease-related) elevation of body
temperature.
To ensure a reliable reading follow these recommendations:
•Do not take a reading while eating, talking, drinking alcohol, smoking, exercising,
and bathing for more than 30 minutes before taking your measurement. Rest for 15
minutes before taking the measurement.
•Do not take measurement when you have been exposed to extreme temperature.
•Remain still and do not talk during measurement..
