2.5GHz are used to reduce the possibility of interference resulted from
mobile/portable communication devices which are accidentally taken into patient's
location. For this reason, additional factor 10/3 is used for calculation of
recommended distance to the transmitter within these frequency ranges.
c) Theoretically, field strength of fixed transmitters, such as wireless (cellular/cordless)
phone and mobile ground radio base station, amateur radio, FA/FM radio broadcast
and TV broadcast, cannot be estimated accurately. Evaluation of EMI environment of
fixed radio frequency transmitter should take into consideration survey at EM
locations. If field strength measured at the place where E6 Emergency Ventilator is
located is higher than the aforesaid applicable radio frequency compliance level,
then E6 Emergency Ventilator shall be observed to verify its normal operation. If any
abnormal property is found, related remedial measure may be required, such as
re-adjustment of orientation or position of E6 Emergency Ventilator.
d) Throughout the frequency range of 150kHz~80MHz, the field strength should be
lower than 3V/m.
Recommended distance between portable and mobile RF communication
equipment and E6 Cardiopulmonary resuscitator
E6 is intended for use in RFI-controlled EMI environments. Based on the maximum rated
power of related communication equipment, purchaser or user can prevent EMI by
maintaining the minimum distance between portable and mobile RF communication
equipment and E6 as recommended below.
