About This Manual
Manual Purpose
This manual describes the safe and effective operation of the MAC 1200/
1200 ST unit.
127(
This document describes the functionality of the international (non-
U.S.) interface for the MAC 1200/1200 ST unit.
Information in this manual differs from operating information for
MAC 1200 units developed for use in the United States. Please refer
to PN 2012250-022 for information on using the U.S. interface.
MAC 1200/1200 ST
The MAC 1200/1200 ST is a electrocardiograph with the following
performance features.
Electrocardiograph equipped with standard software for the following
modes of operation.
 Automatic (acquisition of 12 leads of ECG for a period of 10 seconds)
 Manual (real-time recording of 6 ECG leads)
 Arrhythmia (recording of 6 ECG leads with continuous arrhythmia
analysis)
The graphics display shows 3 leads at a time.
Resting ECGs acquired in the automatic operating mode can be
transferred BETWEEN the MAC 1200 and a PC and FROM the MAC
1200 to a MUSE CV system via the RS232 interface.
The unit operates on AC line power and can also be powered from a
rechargeable battery. The unit can be ordered with an optional
integrated suction pump for the electrode application system KISS.
The performance features of the MAC 1200 / 1200 ST can be upgraded
with the following optional programs.
 MEAS — measurement of the 10-second resting ECG
 DIAG — interpretation of the 10-second resting ECG
 MEMO — storage of a maximum of 40 10-second resting ECGs
 ERGO — stress test ECG (MAC 1200 ST only)

The Basics: About This Manual
Both versions of the electrocardiograph have a configuration menu to
customize the system setup.
Patient and user data can be entered for reliable and safe archiving of
patient records. The patient name is annotated on each printed sheet. All
other data are printed on request.
The MAC 1200/1200 ST units are designed to comply with IEC 60601 /
EN 60601 requirements. They are protection class I devices/devices with
an internal power source. They are classified as MDD class IIa devices.
They are designed for continuous operation. The units are not suitable
for intracardiac application. The units are not intended for use as vital
signs physiological monitors.

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 requirements cannot be met, operate
the device on battery power.
 Do not use multiple portable socket outlets (MPSO)
to connect the device to the power line.
 Devices may be connected to other devices or to parts
of systems only when it has been made certain that
there isno danger to the patient, the operators, 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
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).
