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
a . It
may be necessary to take mitigation measures, such
as re-orienting or relocating the monitor or shielding
the location.
Complies
a The monitor 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 monitor is intended for use in the electromagnetic environment specified below. The customer or the
user of the monitor should assure that it is used in such an environment.
