Emissions And Immunity; Avoiding Electro-Magnetic Interference - Philips Patient Telemonitoring Set Instrucciones De Uso

Emissions
The EMC standards state that manufacturers of patient-coupled
and
equipment must specify immunity levels for their devices when there is
Immunity
reduced performance.
During the EN 61000-4-3 Radiated Immunity test, some reduced
performance was observed.
EN 61000-4-3 specifies that devices be subjected to a field of 3 Volts/
meter over a frequency range of 26 to 1000 MHz with no degradation of
performance or loss of function below the performance level specified
when equipment is operated as intended. Radio communication from the
Philips Telemonitoring Set devices may occasionally be interrupted when
subjected to frequencies in the 800 MHz - 942 MHz range at field
strength levels as low as 0.05 V/m. The phenomena discussed above are
not unique to this unit but are characteristic of radio instrumentation in
use today. The M3812A Home Hub and M3812B TeleStation are radio
receivers and their reception of Philips Telemonitoring Set device signals
can be degraded by electromagnetic interference.
Avoiding The Philips Telemonitoring System is intended for use in an
Electro- electromagnetic environment in which radiated RF disturbances are
magnetic controlled. The customer or the user of the Philips Telemonitoring
Interference System can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the Philips Telemonitoring System as
recommended below, according to maximum output power of the
communications equipment.
The M3812A Home Hub and M3812B TeleStation contain a sensitive
radio receiver that is intended to receive radio signals from the
measurement devices and can be degraded by electromagnetic energy in
the frequency range of 870 MHz to 960 MHz. Avoid the use of any radio
frequency device operating in this frequency range when using the
Philips Telemonitoring System. Possible sources of interfering radio
frequency radiation are cellular telephones, cordless telephones, and
other products that contain radio transmitters. The following table gives
safe distances to keep radio frequency transmitters away from your
Philips Telemonitoring Set devices.
