The Basics: MAC 1200 Resting ECG Analysis System Option Codes

Intended Use and Functional Description

The MAC 1200 is an ECG acquisition and recording system designed and
manufactured by GE Medical Systems Information Technologies.



It is intended to be used for resting ECG recording and realtime ECG
recording with or without arrhythmia detection.



It is not intended for use as a vital signs physiological monitor.



The arrhythmia detection porti on of the M AC 1200 is pr ovided to the
customer for the convenience of automatic documentation. It is not
designed to provide alarms for arrhythmia detecti on .



The MAC 1200 offers no diagnostic opinion to the user. Instead it
provides ana lytical statement s when configured wi th the appropriate
options.



It is intended to be used by trained operators under direct physician
supervision when ECG records are required.



It is not suitable for intracardiac application.



It is designed for continuous operati on.



It is not intended for home use.



The MAC 1200 is designed as a portable device and can easily be
moved from one patient to another or to different locations. It is not
intended to be used during patient transport.

Equipped with the standard software, the MAC 1200 supports the
following operating modes.



12 Lead Mode (acquisition of 12 leads of ECG for a period of 10
seconds),



6 Lead Mode ( realtime recording of 6 ECG leads), and



Arrhythmia Mode (continuous ECG analysis for arrhythmias).

The graphics display shows 3 leads at a time.
Resting ECGs can be transferred to the CardioSys/CardioSoft or MUSE

CV Information System via the RS232 interface.
The device operates from b oth AC and DC (recharg eable batt eries) power

sources.

SHOCK HAZARD — Strictly observe the following
warnings. Failure to do so may endanger the lives of the
patient, the user and bystanders.



Before using the device, the operator must ascertain
that it is in correct working order and operating
condition. In particular, all connectors, electrodes as
well as sensors and probes must be checked for signs
of damage. Damaged parts must be replaced
immediately, before use.



When disconnecting the device from the power line,
remove the plug from the wall outlet first, before
disconnecting the cable from the device. Otherwise
there is a risk of coming in contact with line voltage
by inadvertently introducing metal parts in the
sockets of the power cord.



The mains plug must be connected to an appropriate
power supply with a non-fused grounded-to-earth
wire. If these requiremen ts cannot be met, operate
the device on battery power.



Do not use multiple portable socket outlets (MPS O)
to connect the device to the power line.



Devices may be connected t o other devices or to parts
of systems only when it has been made certain that
there is no danger to the pat ient, the opera tors, or the
environment as a result. In those instances where
there is any element of doubt concerning the sa fety of
connected devices, the user must contact the
manufacturers concerned or other informed experts
as to whether there is any possible danger to the
patient, the operator, or the environment as a result
of the proposed combination of devices. Standards
IEC 60601-1-1/EN60601-1-1 must be complied with
in all cases.



All devices of a system must be connected to the same
electric circuit. Devices which are not connected to
the same circuit must be electrically isolated (isolated
RS232 interface).

EQUIPMENT FAILURE — Magnetic and electrical
fields are capable of interfering with the proper
performance of the device. For this reason make sure
that all peripheral devices operated in the vicinity of the
recorder comply with the relevant EMC requirements. X­ray equipment, MRI devices, radio systems (cellular
telephones) etc. are possible sources of interference as
they may emit higher leve ls of electr omagneti c radiati on.
Keep the recorder away from t hese devices and verify the
recorder performance before use.

SUFFOCATION HAZARD — Dispose of the packaging
material, observing the applicable waste-control
regulations. Keep the packaging material out of
children's reach.

&$87,216

EQUIPMENT DAMAGE — Devices intended for
emergency application must not be exposed to low
temperatures during storage and transport to avoid
moisture condensation at the application site. Wait until
all moisture has vaporized before using the device.

EQUIPMENT DAMAGE — Before connecting the device
to the power line, verify that the ratings of your local
power line are those indicated on the device nameplate.

RESTRICTED SALE — U.S. federal law restricts this
device to sale by or on the order of a physician.
