Short-range radio connections are subject to interruption due to
interference from other radio sources in the vicinity, including
microwaves, bluetooth devices, and DECT phones. Outside the
frequency band and 5% above and below, i.e. the exclusion band
according to IEC 60601-1-2, the short-range radio connection is immune
up to 3V/m in the frequency range from 80MHz to 2.5 GHz. Depending
on the strength and duration of the interference, the interruption may
occur for an extended period. Any interruption of the signal due to
interference, moving out of range, or for other reasons is indicated with
a Tele Disconnected INOP message on the IntelliVue Patient Monitor.
Philips recommends that when using a pouch to attach the MX40 to your
patient that you consider your patient's condition and are careful about
placement of the straps as the straps could present a strangulation hazard.
