Product Introduction
(1) Overview
The JPD-FR302 infrared thermometer (referred to as thermometer
in the following) is a measurement instrument that uses the infrared
receiving principle to measure the temperature in the tympanic
membrane of the earhole. You only need to insert the temperature
probe into the earhole and place it at the correct position, and press
the measurement key to quickly and correctly measure the ear
temperature.
(2) Product Structure
This product mainly consists of a casing, a liquid crystal display, a
press key, a buzzer, an infrared sensor, and a microprocessor.
(3) Measurement Principle
The infrared thermometer uses the infrared temperature sensor to

NOTE 2 These guidelines may not apply in all siluations.
Eleclromagnetic propagation is affected by absorption and
reflection from slructures, objecls and people.
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 JPD-FR302
is used exceeds the applicable RF compliance level above，the
JPD-FR302 should be observed to verify normal operation. If
abnormal performance is observed，additional measures may
be necessary，such as re-orienting or relocating JPD-FR302.
Over the frequency range 150 kHz to 80 MHz，field slrengths
should be less than 3V/m.

can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz，the separation distance for the
higher frequency range applies.
