Revision History
This manual is subject to the GE Medical Systems Information Technologies change order service. The
revision code, a letter that follows the document part number, changes with every update of the manual.
The initial version of the manual has the letter A.
The Dash Responder is a lightweight, portable defibrillator which must be connected to a Dash 2000 or
Dash 3000/4000 patient monitor for operation.
The Dash Responder is available with or without transcutaneous pacer.
The Dash Responder is powered from a rechargeable battery which is inserted into t he device. A new
fully charged batter y provides power for approx. 60 shocks with 360 J each or for approx. 5 hours of
pacemaker operation at an average pulse rate and pacer output (75 ppm, 100 mA).
The Dash Responder will not operate unless equipped with the battery.
The battery charges automatically when the system (patient monitor and Dash Responder) is connected
to the power line and both devices are not turned on. When the devices are on, the battery will charge
only when the Dash Responder does not require the full energy for operation the patient monitor is able
to deliver.
The Dash 3000/4000 also charges the defibrillator battery when disconnected from power line. A
separate, optional charging unit (ASU 3000) is available for battery charging.

PCB Analog
Block Diagram
The PCB Analog provides the following functions:
• Charging of the High-Voltage Capacitor.
The PIC-controllers initiate the charging of the high voltage capacitor to a voltage provided by the
main software on the PCB digital. One PIC supervises the other during the charging to make sure,
the selected voltage will not be exceeded. In the next charging cycle the PICs change place and the
first is supervised by the second.
• Shock delivering and measuring of applied energy.
The PIC-controllers initiate the switching of the relais to deliver the energy to the patient according
Servicing Manual Dash Responder V1.0Revision F

to a command sequence of the main software. The energy which was delivered to the patient is
measured and the value transfered to the main software.
• Control of all subsystems (Powermanagement, Analog, Pacer).
• Display
The display is connected to the PCB Digital that contains a graphic controller.
• Keypad
Any pressed keys are decoded by the PCB Digital and the LEDs on the keypad get illuminated
under control of the PCB Digital.
• Sound generation
The alarm sounds are generated and amplified on the PCB Digital by a sound chip.

PCB Power Management
Block Diagram
The PCB Powermanagement provides following functions:
• Charging and Conditioning (Discharge / Charge-cycle) of the battery
The battery gets charged if it n eeds to be and if energy is provided by a monitor connected to the
Dash Responder. The PCB Powermanagement powers the device and guarantees that every
remaining energy from the monitor is used to charge the battery, but the drawn current does not
exceed the maximum current the monitor is able to deliver.
During the conditioning cycle the battery gets fully depleted and afterwards fully recharged to
regain the optimal energy level.
• Communication with the battery charge level monitoring system which is integrated in the battery
In the service menu the energy level of the battery and the number of conditioning cycles are
given.
• Unregulated P ower supply for subsystems
The Powermanagement regulates the supply voltage to a value that the battery gets charged if
needed and the supply current drawn from the monitor so that the maximum current is not
exceeded.

Battery
The battery in the Dash Responder is a rechargeable NiCd battery with a charge level of 2000 mAh and
nominal 12 Volt (10 cells).
The battery contains a charge level monitoring system to measure the remaining charge in the battery.
By pressing the key on the battery front the actual charge level can be displayed.
Nevertheless, the displayed charge level provides no information about the quality and usability of the
battery. A worn out battery may still possess its capacity but—as a result of an i ncreased internal
resistance—is only partially operational in the defibrillator. The batteries should be periodically tested
in the ASU 3000.
Batteries 2009219-001
General Information
Rechargeable batteries require special maintenance and continued checks to assure they function in
emergency situations. It is normal for batteries of this type to self-discharge, even when the device is
switched off or in storage.
Furthermore, the battery capacity decreases with age: the storage capacity of older batteries is less than
that of new batteries. By regular maintenance (charging and discharging at regular intervals) the battery
service life can be considerably extended.
Battery type 2009219-001 allows you to determine the charge level and capacity at any time.
Furthermore, the LEDs on these batteries indicate
-the presence of a short-circuit (a distinction is made between a short-circuit in the device
(excessive current drain) and a short-circuit between battery cells),
-a display problem,
-the imminent shut-down of the display to protect the battery from over-discharging.

Automatic shut-dow n of the display ( protection from deep discharging)
To protect the battery from deep discharging, the display shuts down automatically. The imminent
shut-down is indicated by running lights, with each of the 5 LEDs blinking in sequence for about 1
second. The display reactivates automatically when the battery is being charged.
Battery conditioning
The battery should be conditioned with the internal battery conditioning program or with the optional
battery charging unit ASU 3000 every month. As t he ASU 3000 is a specially designed battery
charging unit that has a definite conditioning mechanism, it is advisable to use it to condition the
battery. Furthermore the conditioning cycle will last about twenty-one hours if performed in the
defibrillator and only five hours in the ASU 3000.
NOTE
Since the battery will be discharged in the course of the program and the program takes several hours to
complete, a second charged battery must be available to ensure that the defibrillator is ready for use.
The conditioning program can only be run when the defibrillator is connected to the patient monitor
and the monitor, in turn, is connected to the power line.
Start of Conditioning
• Connect the monitor-defibrillator system to the power line.
• Turn the defibrillator on.

Defective Battery
As soon as the battery quality (“F/NEW”) drops to 60% or less, the battery must be replaced by a new
one.
Battery replacement
NiCd batteries have a limited service life time as their storage capacity deteriorates with age. For this
reason, the battery must be replaced every 2 years.

6Replacing PCBs
Safety Information for Disassembly
Please observe the following safety information when disassembling the defibrillator.
All PCBs contain semiconductors which must be protected from electrostatic discharge. When
working on open devices and when handling PCBs, it is important to observe ESD safety precautions.
Please read also the paragraph Electrostatic Discharge (ESD) on page 33. It is especially important
that service personnel always establish contact between the PCB and ground before touching a
component.
Use the following ESD protection guidelines when working on an open defibrillator or when handling
PCBs.
• Use an ESD protective underlay connected to a non-fused earth conductor potential.
• Connect yourself to the ESD protective underlay via an armband.
• Use an ESD protective travel bag to transport PCBs.
The following tools may be required for disassembling the unit:
• Goose-necked tweezers
• Phillips Screwdriver, Type “Phillips-recess” sizes 0, 1 and 2
• Swivel wrench 7 mm for hexagonal spacers
• ESD packaging for PCBs
• ESD underlay with armband
NOTE
The Checkout Procedures and Electrical Safety Tests must be performed each time the device has been
opened, a circuit board is removed or replaced.
Disassembly Procedure
Before any service interventions, turn off the device and remove the battery.
Opening Unit
To open the unit, do the following:
• Lay the defibrillator upside down on a clean, level surface (ESD pad) which is placed on a soft
material.
• Undo the 4 buried screws on the bottom beneath the feet of the device to dismount the upper and

7Troubleshooting Tips
Electrostatic Discharge (ESD)
CMOS Components
The defibrillator makes extensive use of CMOS components because they are more immune to noise
and consume less power than standard TTL or NMOS components. However, CMOS components are
inherently more susceptible to electrostatic discharge ( ESD) damage than other types of semiconductor
materials. ESD damage, causing a weakening or complete breakdown of p-n junctions within
multilayer semiconductor substrates, can range from slight degradation to catastrophic failure. Slight
degradation usually results in intermittent failure of the affected component catastrophic failure results
in rendering the affected component permanently unusable. Although CMOS components may be
more sensitive to ESD, all semiconductor devices are susceptible to ESD damage.
All external connector inputs and outputs of the defibrillator are designed with protection from ESD
damage. Ho wever, if the defibrillator requires service, exposed components and assemblies contained
within are susceptible to ESD damage. This includes human hands, non-ESD protected work stations
and/or improperly grounded test equipment.
The following guidelines help make a service workstation more resistant to the ESD damage:
• Discharge any static charge you may have built up before handling semiconductors or assemblies
containing semiconductors.
• A grounded, antistatic wristband (3M part number 2046 or equivalent) or heel strap should be
worn at all times while handling or repairing assemblies containing semiconductors.
• Use properly grounded soldering and test equipment.
• Use a static-free work surface (3M part number 8210 or equivalent) while handling or working on
assemblies containing semiconductors.
• Do not remove semiconductors or assemblies containing semiconductors from antistatic containers
(Velo-stat bags) u ntil absolutely necessary.
• Make sure power to an assembly is turned off before re moving or inserting a se miconductor.
• Do not slide semiconductors or electrical/electronic assemblies across any surface.
• Do not touch semiconductor leads unless absolutely necessary.
Semiconductors and electrical/electronic assemblies should be stored only in antistatic bags or boxes.
These guidelines may not guarantee a 100% static-free workstation, but can greatly reduce the potential
for failure of any electrical/electronic assemblies being serviced.
Special Components
Surface mounted devices are used to aid in miniaturizing the electrical/electronic assemblies within the
defibrillator.
Surface mounted integrated circuits have legs that are soldered to rectangular pads on the surface of the
printed circuit board (PCB), versus pin-through devices having legs that are made to be inserted into
solder fillets protruding completely through a PCB. Surface mounted integrated circuits (ICs, SMD,
PLCC) may have legs on either two or four sides of the IC. Another surface mounted technology are
Ball Grid Array ICs (BGA) using soldering balls as electrical connections on the bottom of the
components.
Surface mounted resistors, capacitors, and diodes have conductive parts acting as legs that are directly
soldered to the PCB.
WARNING
Surface mounted components were not designed to b e removed or replaced using standard soldering
equipment. Removal of surface mounted components using a conventional soldering iron can

potentially destroy the PCB. Only soldering workstations specifically designed for surface mount
technology may be used to remove and replace these type of components.

11 Maintenance and Technical Inspection
Schedule
To make sure the defibrillator remains in proper operational and functional order, a good maintenance
schedule must be adhered to. The manufacturer’s reco mmendations in this regard is as follows:
Inspection—Operators should perform this prior to admitting each patient to the defibrillator. Service
personnel should perform this prior to servicing the defibrillator. As a general rule, the battery
conditioning program should be run as part of the inspection (internal conditioning program or
separate charging unit ASU 3000).
General cleaning—Operators should perform this prior to admitting each patient to the defibrillator.
Service personnel should perform this after servicing the defibrillator.
Checkout Procedures—These should be performed by qualified service personnel upon receipt of the
equipment, every year thereafter, and each time the defibrillator is serviced.
Leakage Current Tests—These should be performed by qualified service personnel upon receipt of
the equipment, every year thereafter, and each time the defibrillator is serviced.
Calibration—Calibration of t he shock energy measurement should be performed by qualified service
personnel as soon as the yearly performed accuracy check showed deviation of the shock energy
levels compared to those provided in the table on page 57. The calibration should also be
performed whenever a circuit board is removed, repaired or replaced in the defibrillator. The
calibration should also be performed if the software was updated.
Manufacturer Responsibility
Failure on the part of all responsible individuals, hospitals or the institutions, employing the use of this
defibrillator, to implement the recommended maintenance schedule may ca use equipment failure and
potential operator and patient health hazards. The manufacturer does not in any manner, unless an
Equipment Maintenance Agreement exists, assume the responsibility for performing the recommended
maintenance schedule. The sole responsibility rests with all individuals, hospitals, or institutions
utilizing the defibrillator.
Visual Inspection
Carefully inspect the defibrillator prior to each patient being admitted to the monitoring s ystem.
Follow theses guidelines when inspecting the equipment:
• Carefully inspect the defibrillator for obvious physical damage to the outer case, display screen
and controls. Do not use the defibrillator if physical damage is evident. Refer damaged
equipment to qualified service personnel for repair before using it again on a patient.
• Inspect all external connectors, top and rear, for degraded pins, prongs and connector housings.
Refer damaged equipment to qualified service personnel for repair before using it again on a
patient.
• Inspect all cable insulation, cable strain-reliefs and cable connectors for damage, cracks or
degradation. Refer damaged equipment to qualified service personnel for repair before using it
again on a patient.
• The defibrillator electrodes as well as handles must be free of any cream residues.
• Safety labels and inscriptions on the device are clearly legible.
General Cleaning
Clean external surfaces
The exterior surfaces may be cleaned with a lint - free cloth da mpened with one of these approved

Patient (Sink) Leakage Current Test
(Mains Voltage on the Applied Part)
This procedure only applies to Class I (grounded/earthed) equipment, and measures the leakage current
from a mains voltage source into each of the paddles.
The measurement should be made with a patient monitor connected to the defibrillator. Only in cases
where the defibrillator is used stand-alone the measurement can be performed with a service tool box
connected to the defibrillator. In this case the leakage current has to be measured at the ground plug of
the service box. Disconnect the service tool box from all other connections (e.g. PC, po wer supply
etc.).
WARNING
The following step will cause high voltage (120 VAC to 240 VAC) to appear at the PATN JACK on
the leakage tester. Do not touch the PATN JACK posts or paddle lead clips during this test as an
electrical shock will occur.
Referring to the electrical diagram, measurements have to be done under the following conditions:
• Polarity switch NORM and RVS
• GND switch GND closed
• If the Service Tool box is used, the GND plug of the service tools box has to be connected to the
GND plug on the leakage tester
1. Read leakage current indicated on DMM.
If the reading is greater than the appropriate specification below, the device under test fails this test and
should be repaired and tested again.
• 100 µA (0.05 volts on the DMM) at 120 – 240 VAC with external paddle electrodes.
• 50 µA (0.05 volts on the DMM) at 120 – 240 VAC with internal paddle electrodes.
NOTE
The 50 µA limit is according to ANSI/AAMI DF2. The leakage current is measured from each paddle.
2.Change the leakage tester polarity switch to the RVS position.
3. Read the leakage current indicated on the DMM. If the reading is greater than t he appropriate
specification below, the device under test fails this test and should be repaired and tested again.
• 100 µA (0.05 volts on the DMM) at 120 – 240 VAC with external paddle electrodes.
• 50 µA (0.05 volts on the DMM) at 120 – 240 VAC with internal paddle electrodes.
NOTE
The 50 µA limit is according to ANSI/AAMI DF2. The leakage current is measured from each paddle.
