Foreword Introduction
Foreword
This manual is intended to provide information required to properly service the Datascope
CS300 Intra-Aortic Balloon Pump.
Warnings, Precautions and Notes
Please read and adhere to the following list of warnings, precautions and notes; some of
which are repeated in the appropriate areas throughout this manual.
A WARNING is provided if there is reasonable evidence of an association of a serious
hazard with the misuse of this device or when special attention is required for the safety of
the patient.
A PRECAUTION is provided when any special care is to be exercised by the practitioner to
avoid causing damage to this device or other property. They may also include actions to be
taken to avoid effects on patients or users that may not be potentially life threatening or result
in serious injury, but about which the user should be aware.
A NOTE is provided when extra general information is applicable. Notes appear in the
appropriate areas throughout the manual.
Warning
WARNING: Compressed gasses (helium cylinders) are considered
Dangerous Goods/Hazardous Materials per I.A.T.A. and
D.O.T. Regulations.
It is a violation of federal and international law to offer any
package or over pack of dangerous goods for
transportation without the package being appropriately
identified, packed, marked, classified, labeled and
documented according to D.O.T. and I.A.T.A. regulations.
Please refer to the applicable I.A.T.A. Dangerous Goods
Regulations and / or the Code of Federal Regulations 49
(Transportation, Parts 171-180) for further information.
WARNING: Preventive Maintenance should not be performed when the
IABP is attached to a patient.
Precautions
CAUTION: Do not short component leads together.
CAUTION: The troubleshooting charts are not intended as a rapid
course on how to repair devices of this type. Rather, they
are intended as a guide for qualified technical personnel
only. The instrument covers should only be removed by
technically qualified personnel who have received
supplementary instructions regarding maintenance of
medical electronic equipment or have had equivalent
experience in this area.

CAUTION: The accidental shorting of component leads can easily over
CAUTION: To avoid damage, do not use the high powered iron to
stress components, resulting in a second unnecessary failure
(aside from creating a possible safety risk).
repair printed wiring boards as the conductors will lift from
the surface under the extreme heat.
Notes
NOTE: Datascope maintains a policy of continual product
improvement and reserves the right to change materials
and specifications without notice.

Theory of Operation
The Theory of Operation is divided into two parts. The first part contains block diagrams for
the entire system, including cabling, and pneumatics. It should be used by service personnel
to become familiar with the internal organization of the instrument. The second part contains
PCB drawings, the related block diagrams, and a brief circuit description.
CS300™ Service Manual 0070-10-0689 1 - 1
System Block Diagrams Theory of Operation
1.1 System Block Diagrams
The Block Diagrams indicate the internal organization of the instrument. They are used to
gain familiarity with the instrument and to locate malfunctioning PC boards as readily as
possible. To avoid clutter, the number of PC board interconnects is minimized. The
interconnects shown represent major or essential signal flow and clock connections.
