Guidelines and manufacturer's statement – electromagnetic noise
HeartScreen80G-L1 was manufactured for use within the electromagnetic environment stated below.
Buyer or user of HeartScreen80G-L1 must ensure that the unit is operated within this environment.

st
1 : In case of 80 MHz and 800 MHz, the higher frequency range must be applied.
NOTE
nd
2 : These guidelines must not be used in every case. Electromagnetic transmission is influenced

by absorption and reflection caused by buildings, objects and people.
a
It is not possible to define accurately the field intensity of stable transmitters, for instance
transmitters of cellular phones, mobile radios, AM/FM radios and television broadcasting. To
get to know the electromagnetic environment of the stable R/F transmitters, on site
measurements shall be made. In the case of the field intensity at site of the operation of
HeartScreen80G-L1 exceeds the relevant RF conformity level
must be checked. In case improper operation is detected, further
HeartScreen80G-L1
arrangements have to be taken, e.g. it may be necessary to rotate
install it at a different site.
b
Field intensity above the frequency range of 150 kHz and 80 MHz must be lower than [V1]
V/m.
