Emissions and immunity information
Electromagnetic emissions
The 901103 is intended for use in the electromagnetic environment specified below. The customer or user of the 901103
should assure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment - guidance
RF emissions
CISPR 11 Group 1 The 901103 uses RF energy only for its internal function. Therefore, its
RF emissions are very low and are not likely to cause any interference
in nearby electronic equipment.
RF emissions
CISPR 11 Class B
The 901103 is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low voltage
power supply network that supplies buildings used for domestic
purposes.
WARNING This equipment/system is intended for
use by healthcare professionals only. This
equipment/ system may cause radio interference or
may disrupt the operation of nearby equipment

. It
may be necessary to take mitigation measures, such
as re-orienting or relocating the 901103 or shielding
the location.

a
The 901103 contains a 5-GHz orthogonal frequency-division multiplexing transmitter or a 2.4-GHz frequency hopping
spread-spectrum transmitter for the purpose of wireless communication. The radio is operated according to the
requirements of various agencies, including FCC 47 CFR 15.247 and R&TTE Directive (1995/5/EC). The transmitter is
excluded from the EMC requirements of 60601-1-2, but should be considered when addressing possible interference
issues between this and other devices.
Electromagnetic immunity
The 901103 is intended for use in the electromagnetic environment specified below. The customer or the user of the
