DANGERS
EXPLOSION HAZARD — Do not use this
equipment in the presence of flammable anesthetics,
vapors or liquids.

Preparations for ECG Recording
227 492 04-D MAC® 1200 13
WARNINGS
ACCESSORIES (SUPPLIES) — Use only the
original GE Marquette cables. Do not connect other
signal sources to the cables. The user is responsible
for the use of accessories from other manufacturers.
ACCIDENTAL SPILLS — To avoid electric shock
or device malfunction liquids must not be allowed to
enter the device. If liquids have entered a device,
take it out of service and have it checked by a
service technician before it is used again.
BEFORE USE — Before putting the system into
operation visually inspect all connecting cables for
signs of damage. Damaged cables and connectors
must be replaced immediately.
BEFORE USE — Before using the device, the
operator must verify that it is in correct working
order and operating condition. For instructions, refer
to section 3.2.2 “Performance Check” in this
chapter.
CONDUCTIVE CONNECTIONS — Do not allow
electrodes to come into contact with conductive
parts. The neutral electrode, in particular, must not
be connected to earth.
DISCONNECTION FROM MAINS — When
disconnecting the system from the power line,
remove the plug from the wall outlet first. Then you
may disconnect the power cord from the device.
MOISTURE CONDENSATION — Devices
intended for emergency application must not be
stored or transported at temperatures which cause
moisture condensation at the application site. Wait
until all moisture condensation has evaporated
before using the device.
MPSO—The use of a multiple portable socket outlet
(MPSO) for a system will result in an enclosure
leakage current equal to the sum of all individual
earth leakage currents of the system if there is an
interruption of the MPSO protective earth conduc-
tor. Do not use an additional extension cable with
the MPSO as it will increase the chance of the single
protective earth conductor interruption.
OPERATOR — The user must have received
adequate training in the use of the MAC 1200 and
must be capable of applying it properly.
POWER SUPPLY — The device must be connected
to a properly installed power outlet with protective
earth contacts only. If the installation does not
provide for a protective earth conductor, disconnect
the monitor from the power line and operate it on
battery power, if possible.
If the installation of this equipment in the USA will
use 240V rather than 120V, the source must be a
center-tapped, 240V, single phase circuit.

Preparations for ECG Recording
14 MAC® 1200 227 492 04-D
CAUTIONS
MAINTENANCE — Regular preventive mainte-
nance should be carried out annually, inspections of
equipment with measuring functions should be done
every two years (refer to chapter 11 “Cleaning,
Disinfection and Maintenance”).
PERFORMANCE CHECKS — Check the device
performance once a month, strictly following the
instructions outlined in section 3.2.2 “Performance
Check”.
POWER REQUIREMENTS — Before connecting
the device to the power line, check that the voltage
and frequency ratings of the power line are the same
as those indicated on the unit’s label. If this is not
the case, do not connect the system to the power line
until you adjust the unit to match the power source.
VENTILATION REQUIREMENTS — Set up the
device in a location which affords sufficient
ventilation. The ventilation openings of the device
must not be obstructed. The ambient conditions
specified in the technical specifications must be
ensured at all times.
DEFIBRILLATOR PRECAUTIONS — Patient
signal inputs labeled with the CF and BF symbols
with paddles are protected against damage resulting
from defibrillation voltages To ensure proper
defibrillator protection, use only the recommended
cables and leadwires. Proper placement of defibril-
lator paddles in relation to the electrodes is required
to ensure successful defibrillation.
DISPOSAL — Dispose of the packaging material,
observing the applicable waste control regulations
and keeping it out of children’s reach.
ELECTROCAUTERY PRECAUTIONS — To
prevent unwanted skin burns, apply electrocautery
electrodes as far as possible from all other elec-
trodes, a distance of at least 15 cm/ 6 in. is recom-
mended.
EMC — Magnetic and electrical fields are capable
of interfering with the proper performance of the
device. For this reason make sure that all external
devices operated in the vicinity of the monitor
comply with the relevant EMC requirements. X-ray
equipment or MRI devices are a possible source of
interference as they may emit higher levels of
electromagnetic radiation.
INTERFACING OTHER EQUIPMENT — Devices
may only be interconnected with each other or to
parts of the system when it has been determined by
qualified biomedical engineering personnel that
there is no danger to the patient, the operator, or the
environment as a result. In those instances where
there is any element of doubt concerning the safety
of connected devices, the user must contact the
manufacturers concerned (or other informed experts)
for proper use. In all cases, safe and proper operation
should be verified with the applicable manufac-
turer’s instructions for use, and system standards

the MAC 1200 resting ECG analysis system
connected to the power line whenever possible.
After 4 hours the battery has regained its full
capacity.
The battery low indicator 22 is illuminated when
battery needs to be charged.
With a full battery, about 50 ECGs (1 page) can be
recorded in 12 Lead Mode. When its capacity drops
to about 25 recordings, the battery is used up and
must be replaced by a service specialist.
Note
To prolong the battery life, discharge the battery at
least once per month (by operating the resting ECG
analysis system on battery power).
Note
In standby mode, a fully charged battery is drained
within approx. 4 hours. Therefore, when operating
the device on battery power, be sure to turn it off

Note
–When turning off the MAC 1200 (standby mode),
be sure to press the power switch long enough.
–The backlighting of the display switches off
automatically when no key is activated for 5
minutes (adjustable).
–Run the full self-test at least once a day to ensure
that the device is functioning properly.
3.3 Installation and Mains Connection
Figure 3-2 shows a practical arrangement of patient
and recorder. For interference-free operation, it is
important that the patient cable and the power cord
do not run parallel.
•Using the power cord, connect the device to the
power line (Figure –3-1). Use only the original
power cord or an equivalent cable.
The standby indicator 23 will illuminate.
•Check the paper supply (the window in the paper
door allows you to look inside the compartment).
If it is necessary to insert a new paper pad, refer
to chapter 10 for instructions.
3.4 Performance Check
•Press the power switch to switch on the device
(Figure 3-4).
The amber stop indicator 20 will illuminate.
After power-up, the resting ECG analysis system
runs an automatic self-test. When no problem is
detected, it defaults to the 12 Lead Mode. If a
malfunction is identified, the display will show an
error message “Error...”. In this situation, notify
service to check and repair the device.
The self-test can be aborted with the

button. In
this case, the device immediately activates the 12
Lead Mode.
Contrast Adjustment
•To adjust the contrast, simultaneously press
alt
and the appropriate cursor key:
for more contrast, for less contrast.

Warning
Shock Hazard — Strictly observe the following
warnings. Failure to do so may endanger the lives of
the patient, the user and bystanders.
−Connecting peripheral devices to the RS232
interface of the resting ECG analysis system cre-
ates a medical system. This system must meet the
requirements of IEC 60601-1-1.
−Use only the original Marquette Hellige connec-
tion cables.
−All non-medical 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 (use isolated RS232 inter-
face as per IEC 60601-1).
−A PC connected to the resting ECG analysis
system should meet the requirements of EN
60601. If it doesn't, it must be set up outside the
patient environment. If the PC fulfills the re-
quirements of EN 60950, it must be set up within
the medically used area, but outside the patient
environment.
−Do not connect PCs to the resting ECG analysis
system that fulfill neither EN 60601 nor EN
60950.
−Modems connected to the resting ECG analysis
system must meet the requirements of EN 60950
or UL1950 (all modems recommended by
Marquette Hellige meet these requirements). The
specific regulations valid in your country must
also be observed.
The modem must be set up within the medically
used area, but outside the patient environment.
3.6 Connecting External Devices
Via the serial interface, the resting ECG analysis
system can be connected to a MUSE CV Informa-
tion System. These external devices can be
connected directly or via a modem. Please contact
GE Marquette Application Support for details.
Resting ECGs acquired in the 12 Lead Mode as well
as the corresponding data can be transferred to these
external devices (see section 5.5 "ECG Transmis-
sion").
The table below shows the system defaults and all
possible adjustments.
For instructions on changing the default setup, refer
to section 9.6 "Communication".

Warning
Shock Hazard — Strictly observe the following
warnings. Failure to do so may endanger the lives of
the patient, the user and bystanders.
−For reasons of patient safety, use only the origi-
nal GE Marquette patient cable. Before con-
necting the cable to the device, check it for signs
of mechanical damage. Do not use a damaged
cable.
−Ensure that conductive parts (such as the patient,
connectors, electrodes, transducers) that are
connected to the isolated patient signal input do
not come into contact with other grounded, con-
ductive parts. This would bridge the patient's
isolation and cancel the protection provided by
the isolated input. The neutral electrode, in par-
ticular, must not come into contact with ground.
4 Preparations for ECG Recording
4.1 Connecting the Patient Cable
Use the 10-leadwire patient cable for acquisition of
the 12 standard ECG leads.
•Connect the patient cable to connector 3(Figure
4-1).
