Introduction: Safety Information
1-10 MAC 5000 System — 2000657-057, Revision B
Modulating Effects in Digital Systems
This device uses digital sampling techniques that may
produce some variation in amplitudes of Q, R, and/or S
waves from one heart beat to the next, which may be
particularly noticeable in pediatric recordings. If this
phenomenon is observed, the clinician should be aware that
the origin of amplitude variations is not entirely
physiologic. For measuring voltages of Q, R, and S waves, it
is advisable to use the QRS complexes with the largest
deflection of the particular waves.
Installation and Connection
If the installation of this equipment, in the USA, will use
240 V rather than 120 V, the source must be a center-
tapped, 240 V, single-phase circuit.
Contact GE Medical Systems Information Technologies for
information before connecting any devices to this
equipment that are not recommended in this manual.
Parts and Accessories
To ensure patient safety, use only parts and accessories
manufactured or recommended by GE Medical Systems
Information Technologies.
Parts and accessories used must meet the requirements of
the applicable IEC 601 series safety standards, and/or the
system configuration must meet the requirements of the
IEC 60601-1-1 medical electrical systems standard.
The use of ACCESSORY equipment not complying with the
equivalent safety requirements of this equipment may lead
to a reduced level of safety of the resulting system.
Consideration relating to the choice shall include:
n
use of the accessory in the PATIENT VICINITY; and
n
evidence that the safety certification of the
ACCESSORY has been performed in accordance to the
appropriate IEC 60601-1 and/or IEC 60601-1-1
harmonized national standard.
