vapors or liquids.

Putting the Device into Operation and Performance Test
227 492 04-C MAC® 1200 13
WARNINGS
ACCESSORIES (SUPPLIES) — Use only the
original Marquette cables. Do not connect other
signal sources to the cables. The responsibility for
the use of accessories from other manufacturers lies
with the user.
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
conductor. 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.

Putting the Device into Operation and Performance Test
14 MAC® 1200 227 492 04-C
CAUTIONS
MAINTENANCE — Regular preventive
maintenance 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
defibrillator 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
electrodes, a distance of at least 15 cm/ 6 in. is
recommended.
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

regained its full capacity.
The battery low indicator 22 is illuminated when
battery needs to be charged.
With a full battery, about 50 ECGs 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.
Caution
To prolong the battery life, discharge the battery at
least once per month (by operating the electro-
cardiograph on battery power).

The backlighting of the display switches off
automatically when no key is activated for 5 min
(adjustable).
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 electrocardiograph 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.

Warning
−Connecting external devices to the RS232
interface of the electrocardiograph creates a
medical system. This system must meet the
requirements of IEC 60601-1-1:
−use only the original Marquette connection
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
interface as per IEC 60601-1).
−Modems connected to the electrocardiograph
must meet the requirements of EN 60950 or
UL1950 (all modems recommended by
Marquette meet these requirements). The specific
regulations valid in your country must also be
observed.
3.6 Connecting External Devices
Via the serial interface, the electrocardiograph can
be connected to a MUSE CV Information System.
These external devices can be connected directly or
via a modem. Please contact 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 Transmission via Modem").
The table below shows the system defaults and all
possible adjustments.
For instructions on changing the default setup, refer
to section 9.6 "Communication".
