136 Centrella® Smart+ Bed Instructions for Use (193587 REV 10)
Electromagnetic Compatibility Guidance
This device meets all requirements for electromagnetic compatibility per IEC 60601-1-2. It is unlikely
that the user will encounter problems with this device because of inadequate electromagnetic
immunity. However, electromagnetic immunity is always relative, and standards are based on
anticipated environments of use. If the user observes unusual device behavior, particularly if such
behavior is intermittent and associated with nearby use of radio or TV transmitters, cell phones, security
systems (e.g. electromagnetic anti-theft systems, and metal detectors), radio-frequency identification
(RFID) readers, near-field communications (NFC) systems, wireless power transfer (WPT) or electro-
surgical equipment (e.g. diathermy and electrocautery), this could be an indication of electromagnetic-
interference. If such behavior occurs, the user should try to move the interfering equipment further
from this device.
Warning—Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of the Heart and
Respiration Rate Monitoring System powered by EarlySense, including cables specified by Hill-Rom.
Otherwise, degradation of the performance of this equipment could result.
The P7900 and HR and RR Monitoring System—
• Warning—The system should not be used adjacent to or stacked with other electrical
equipment.
• Warning—Observe to make sure that the system and the stacked equipment operate as
intended, if adjacent or stacked use in necessary.
• Warning—Observe to make sure the system operates properly when used near portable and
mobile radio frequency (RF) communications equipment, as these can affect electrical
equipment.
• Warning—Use of accessories, transducers, and cables other than those specified or provided
by the manufacturer of this equipment could result in increased electromagnetic emissions or
decreased electromagnetic immunity of this equipment and result in improper operation. See
the Centrella® Bed Service Manual (193588) for compatible component part numbers.
Medical equipment needs special precautions in regard to electromagnetic compatibility (EMC) and
needs to be installed and put into service according to the EMC information supplied in the tables that
follow.
Guidance and Manufacturer's Declaration—Electromagnetic Emissions
The P7900 and HR and RR Monitoring System are intended for use in the electromagnetic environment specified
below. The customer or the user should make sure they are used in such an environment.
Emissions Test Compliance Electromagnetic Environment—Guidance
RF emissions
CISPR 11
Group 1 The P7900 uses RF energy only for its internal functions. There-
fore, its RF emissions are low and are not likely to cause any inter-
ference in nearby electronic equipment.
RF Emissions
CISPR 11
Class A The P7900 is suitable for use in all establishments other than
domestic establishments and those directly connected to the
public low-voltage power supply network that supplies build-
ings used for domestic purposes.
