Guidance and manufacturer’s declaration - electromagnetic immunity
The Medical Infrared Thermometer is intended for use in the
electromagnetic environment specified below. The customer or user of
the device should ensure that it is only used in such an environment.
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetism is
affected by absorption and reflection from structures, objects and people.
Theoretically, the field strengths of such fixed transmitters as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radios, AM and FM
radio signals and TV signals cannot be predicted with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. The field strength in the location in which the
thermometer is to be used should be measured to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the thermometer. Over the frequency range of 150 kHz to 80
MHz, the field strength should be less than 3 V/m.
