1.3 System overview
1.3.1 Hooking up EAGLE 1000 monitors to PC Central Station SynOpsis 1000
Eagle 1000 monitors version V2.1 and higher can be connected up to the PC Central
Station SynOpsis 1000. This involves the hooking up of up to eight monitors via a serial
cable with an OctaBus 1000. Up to two OctaBus 1000s can be connected up to the
Central Station. Each OctaBus is connected to the Central Station PC using a printer port.
Alarm release ensues from one of the two OctaBus devices, these being connected appropriately. The OctaBus devices and the Central Station PC monitor controll each others
performance and give an alarm when a malfunction is detected. For configuration see
figure below.

Connection
The Nurse Call socket of Eagle 1000 V2.1 or higher is used for hooking up to the Central
Station via the OctaBus. A current loop permits connections over distances of up to 200 m.
Connection to the OctaBus is via an 8-lead cable either from a wall outlet or directly. Refer
to the Installation Instructions for more details.

1.3.2 Patient data transfer from EAGLE 1000 via HELAN to SMU using
QuickLink
1.3.2.1 Introduction
To ensure continuous monitoring it is also necessary to be able to record patients vital
signals during relocation and transportation. However, since during patient transfer there is
no connection to the LAN, the trend data are collected and then transferred later as a
block.
After taking over patient monitoring on the transport monitor recording of the data begins.
No connection is being established with the Gateway. The patient remains anonymous,
i.e., his name is not entered into the transport monitor.
Upon arrival at his new destination the patient is hooked up to the destination monitor and
the transfer of the trend data initiated by the transport monitor operator. The transport
monitor establishes a connection over an IR beam and a terminal server (QuickLink) with
the LAN and transfers the data to the Gateway.
In the Gateway the data are stored in a file bearing a file name indicating the ID of the
transport monitor used. Assignment of patient data is carried out using the operating routines of the destination monitor. The operator selects the transport monitor ID, to which the
transferred patient belonged to. It is now the task of the Gateway to enter the trend data
into the database correctly.
Figure 3 shows the principle of data transfer. The terminal server comprises QuickLink, the
Gateway comprises VICOM TR server or VICOMport + VICOMserver.
Page 13
GE Medical Systems EAGLE 1000 Page 13
Information Technologies Servicing Instructions 227 468 01 Rev. G
1.3.2.2 Data transfer between Eagle and Gateway
Eagle and Gateway will communicate while transferring trend data. Transfer is initiated by
the user request function.
The data are first stored in a file and, when data transfer is complete, arranged in proper
order. The transport monitor waits for the results of this processing procedure.
If an error occurs in the database during this procedure, all the data in the Gateway are
deleted and the entire data must be transferred once more.
When the data transfer is initiated, the time will be sent by the transport monitor real-time
clock. From this the Gateway can identify any possible time misalignment of the internal
clock of the transport monitor and account for this when the trend data are entered.
Sporadic trend data, e.g., non-invasive blood pressure values, are only transferred for the
period of time in which continuous trend data, e.g., ECG, are also available. Earlier or later
parameter readings will be ignored.
1.3.2.3 Connection to the LAN
The QuickLink Station is connected to a Multiport or an SMX using twisted-pair wiring.
The Multiport can lead to the LAN using BNC or AUI wiring.
The SMX 008 leads to the LAN using AUI wiring, the SMX 009 to the LAN using BNC
wiring.

1.3.2.4 EAGLE 1000 - QuickLink - HELAN - Examples of the link to networks
1.3.2.4.1 Functional structure overview
The link of Eagle 1000 to the networks via QuickLink enables the transfer of patient data
acquired during patient relocation and transportation for continuous and uninterrupted
analysis.
A QuickLink adapter connected to the RS 232 interface of the Eagle 1000 sends the transportation data using IR to a QuickLink Station. The QuickLink Station acts as a terminal
server and is the communication partner to the HELAN network.
The data transferred onto the HELAN are stored on a server which acts as a Gateway
(VICOM TRserver or VICOMport in connection with VICOMserver).
This is where the patient data and the measured values recorded during transportation are
made available for complete documentation on any patient monitor or on a clinical information system.

2.2 Functional description of PCBs and subassemblies
2.2.1 Eagle 1000 configuration and functional groups
see diagram Functional groups
The basic Eagle 1000 patient monitor version comprises the large PCB ECG Monitor
installed in the system on the front side of an L-shaped metal plate. In addition to the ECG
input circuit, the instrument control system is also located on this PCB.
The keypad, display screen, battery and the PCB Power Supply are connected to it. Also
connected are the ECG input socket and the two rear panel outputs RS-232 and Nurse
Call.
The keypad and CRT have conductor foil connections and care must be taken when connecting them up and sharply bending them avoided.
The battery is installed in the bottom side of the L-shaped metal plate.
The power supply is located inside the rear panel of the system next to the power supply
socket.
The recorder, if there is one, is mounted on the base plate and connected to the PCB
ECG Monitor.
Page 29
GE Medical Systems EAGLE 1000 Page 29
Information Technologies Servicing Instructions 227 468 01 Rev. G
In the models with additional features the PCB ECG Monitor also acts as a motherboard. The PCB Oximeter, the PCB for non-invasive blood pressure and the PCB for
temperature or for temperature and 2 invasive blood pressures can be added to this
board.
In conformity with Cardiac floating there is a high-impedance isolating transformer referred separately to the ECG input module, the PCB Oximeter, the PCB module for temperature and the PCB module for 2 invasive blood pressures. Both pressure measuring components are electrically connected. These PCBs are insulated from the non-floating components of the system and each other by spacing and insulating foil.
Warning: It is thus important that when disconnecting or replacing PCBs in the
system to ensure PCBs and circuits are correctly installed and the insulating foil positioned accordingly.
2.2.2 PCB ECG Monitor
The PCB ECG monitor appears as a block diagram in the PCB circuit diagrams. The
circuits are arranged so that (viewing Eagle 1000 from the rear) the floating ECG Processing is located in the left-hand third, in the remainder all the other functions:
Floating Non-Floating
x Display Controller
x ECG Controller
x Interface Output
x ECG Filter x Controller
x Power Supply (instrument, battery, floating)
x ECG Input x Interface Input
This means that ECG Processing and the Central System signal processing and system
controller are implemented on this PCB. The description of each is given below, indicating
the connected modules and their functions.
The PCB plugs and sockets are shown in the S-Plan of the system plans and are allocated as listed below. This allocation is useful in finding the pin configuration in the P circuit
diagrams of the PCB ECG Monitor.

2.2.3 System power supply
see diagram System Power Supply
The power supply is in protection class I with a protective ground terminal. A primaryregulated wide-range power supply unit, delivering 15.5 V DC, precludes the necessity of a
power toggle switch. This unit also acts as a charger for the 12-V system battery. All control functions are regulated on the PCB ECG Monitor. A charge controller measures the
battery current across a resistance referred to zero, activates the front panel charge indicator and communicates with the processor. Should the output voltage of the power unit
fail to reach 15.5 V, the battery will not be charged to full capacity.
The battery meets the temporary high current demand of the recorder and the PCB NonInvasive Blood Pressure as well as current peaks and is also essential for retaining data.
As the battery continuously is discharged, this is indicated by an 11.5V comparator, which
triggers the warning display Battery blinking and the audible alarm signal sounding.
When the charge drops below 10 V after storing the data the 10V comparator switches off
the system to protect the battery.
Page 31
GE Medical Systems EAGLE 1000 Page 31
Information Technologies Servicing Instructions 227 468 01 Rev. G
Otherwise, the system is switched on and off with the appropriate button on the front panel, which, just like the 10V comparator, exerts an effect via the processor on the ON/OFF
interface with its FET switch.
A 5V analog voltage +5VREF is generated with a linear controller from the battery voltage
supplied when it is switched on. A switching controller generates the 5V digital voltage
from the battery voltage supplied when it is switched on. Apart from this the battery voltage
supply is used directly and unregulated for oscillators and other components requiring a
power supply.
2.2.4 Floating system power supply and signal flow
Power supply
see diagram Floating system supply and signal flow
The floating system is supplied from a central 100-kHz oscillator on the PCB ECG Moni
tor. This delivers the supply voltage stabilized on a HF transformer, i.e., individual power
fluctuations on some PCBs are not fully compensated. The individual floating components
receive power via the primary HF transformers connected in parallel. Isolation is effected
in these floating transformers. These each generate ±7.5V ±5%. In turn, in each case a
linear +5V ±2% analog/digital voltage is obtained from these voltages.
Signal flow
see diagram Floating system supply and signal flow.
Apart from the non-invasive blood pressure all patient input circuits are high-impedancefloating circuits. In terms of signals, these are isolated in both directions via optoelectronic couplers. All other circuit components are not isolated and referred to circuit zero.
Furthermore, there is a separate ground contact to enable potential equalization.
The non-invasive blood pressure input is isolated by means of a non-electronic patient
input.
2.2.5 Signal exchange with the processor
see Processor block diagram
The processor on the PCB ECG Monitor comprises a controller with a separate 32kHz
quartz crystal, watch dog, RAM and EPROM. The controller is in communication with all of
the following units.
Page 32
GE Medical Systems EAGLE 1000 Page 32
Information Technologies Servicing Instructions 227 468 01 Rev.G
The keypad is used to enter data, the beeper to give alarms and acknowledgment sig
nals. The recorder interface leads to the integrated recorder and the CPU interface to the
liquid-crystal screen.
The RS 232 interface acts as a system output, it is mainly used for sending signals to the
QuickLink to output data to the HELAN after patient relocation and transportation.
The Nurse Call interface leads to the nurse call adapter. A nurse call system can be
connected by means of the nurse call relay for the Eagle 1000. From Version 2.1 and
higher, a 20 mA current loop is available to connect the Eagle to an OctaBus of a SynOpsis Central Station.
The patient data inputs are entered via three serial interfaces:
The QSPI interface allows the transfer of ECG, temperature and the two invasive blood
pressures via the 16 Qued Processor Interface signals. One chip select signal each is
generated for each of the three signal groups. A clock signal synchronizes the transfer of
the two Master In - Slave Out and Master Out - Slave In signals.
The PCBs Oximeter and Non-Invasive Blood Pressure are each connected separately via
an asynchronous interface. This has both an Rx and a Tx cable as well as a reset cable.
Another EC.Syn signal is provided for the oximeter (Sp02), another RESETB signal for the
non-invasive blood pressure (NBP).
2.2.6 Display
see Display block diagram
All of the elements shown apart from the block display are located on the PCB ECG
Monitor.
The LCD display is controlled by an LCD controller. This works together with an external
3.6MHz oscillator and external display RAM. The control of the LCD controller is effected
via the CPU interface.
The LCD display is controlled by a -23V power supply. This voltage is acquired from the
battery voltage supply. The contrast on the PCB ECG Monitor must be adjusted.
The display has a reverse video feature which is supplied with 300 V AC at 30 to 40 Hz
from a CCFT supply. In open-circuit operation this is approx 565 V.
Warning: Avoid contact with this voltage where it is exposed on the PCB ECG
Monitor.

2.2.8 ECG signal preprocessing
2.2.8.1 Functional description
The block diagram ECG/Pace Preprocessing shows the functional setup.
ECG input
In the Eagle 1000 ECG signal acquirement and processing takes place in one of the
remaining functional groups electrically separated from the others on the motherboard.
The functions of this component comprise analog processing of the ECG signals and a
QRS detector to monitor the cardiac rhythm.
All control functions are monitored by a processor, which exchanges data and commands
with the ECG circuit via the optoelectronic coupler.
Before it becomes operative the ECG circuit must be initialized. This is effected by the
processor in accordance with the selected accessories. The processor receives ID signals
called LET1, LET2 and LET3, identifying the nature of the connected accessories and,
hence, determines which ECG leads are available and which connections need to made
to the patient.
For this reason, the lead selector is preset to identify the patient cables used and to test
whether all the electrode leads are connected correctly. Every disconnected (electrode)
lead produces an error signal which is evaluated by the processor so that such electrodes
are not used for ECG monitoring.
ECG signal transfer
If fully operational electrodes are correctly connected to the EAGLE 1000, the ECG signal
is first amplified to 1.1 V per 1 mV as an analog signal, then transferred as a digital signal
via the optoelectronic coupler.
During analog signal amplification signal transfer is interrupted in the event of pacemaker
pulses and the arithmetic mean value is transferred as a baseline in place of the ECG
signal. The digital data are generated 1000 times a second from each of the transferred
amplitude values.
ECGs up to max. ±4.5 mV are digitized completely.
Three-lead patient cables provide only one ECG lead (lead I, II or III) on channel 1, connecting a five-lead cable enables EAGLE 100X to provide one lead each on two channels.
The options are leads I, II, III, AVR, AVL, AVF, V.
Page 39
GE Medical Systems EAGLE 1000 Page 39
Information Technologies Servicing Instructions 227 468 01 Rev. G
Heart rate monitoring
A QRS detector in the ECG circuit detects the beats. This detector filters and triggers the
signal components typical of QRS from the channel 1 ECG signals when their amplitude is
greater than a threshold value arising in the prior amplitudes.
The processor receives a signal for every beat detected by the ECG circuit, calculates the
heart rate from these and triggers an alarm when the heart rate is outside the programmed
limits.
Pacing detection
Signal segments with a steep rising or falling edge are suppressed as long as their amplitude exceeds a value of 6 mV. This suppression is limited to a time period of about 50 ms.
During this period the baseline is recorded and a pacing-pulse message is passed on to
the processor, which puts a marker for this event on the display.

2.2.10 Non-invasive blood pressure module
2.2.10.1 Function
The PCB NBP acquires and automatically processes the non-invasive blood pressure
signal. Via an internal asynchronous connection it passes the non-invasive blood pressure data on to the PCB ECG Monitor. From here it receives a reset signal as well as a
separately controlled pump power supply for safety reasons. The PCB is not electrically
isolated as isolation is effected by the pneumatic signal input.
Warning: For safety requirements, when replacing the PCB it is important to use
the flat strip cable of correct length to match the version used.

2.2.11 PCB Press-Temp 388 031 75/PCB Temp 388 032 04
General information
The PCB PRESS-TEMP enables measurement of the two electrically isolated parameters
temperature (one temperature) and invasive blood pressure (two pressures,both isolated
together). These parameters are connected along with the ECG to the processor by means of a QSPI interface. The signals are isolated by optoelectronic couplers.
The power supply is fed in via one HF transformer each for PRESS and TEMP from a
common oscillator, which also supplies power to the ECG circuit and the SpO2 module.
See block diagram Floating system supply and signal flow.
The PCB is equipped with precision components (and an adjustment program in the case
of TEMP) so that a potentiometer adjustment is not required.
The individual floating measurement circuits are shielded on both sides of the PCB by a
metal cover. For PCBs which do not have an insulating cover over the two floating parts
the PCB is underlayed with a sheet of insulating foil. These insulation precautions are
important for safety reasons!
2.2.11.1 PRESS module
The circuit is described in the block diagram Press block diagram.
Power supply
The floating power supply for PRESS uses an HF transformer connected in parallel with
the other floating transformers. The corresponding oscillator delivers a closed-loop controlled transformer output voltage, which may vary somewhat depending on the load, from the
unregulated battery voltage. This supplies the amplifier and the connection detector with
±7.5 V.
The ADC and digital circuit are supplied by a voltage controller with a stabilized 5 V, in the
form of an analog and a decoupled digital power supply. When the 5V power supply drops
below 4.75 V an error signal interrupts the chip select to ADC so that no incorrect parameter readings can be transferred.
Probe detection
Each PRESS channel is assigned an ID by means of a resistor coding system which, even
in operation via an adapter, informs the system which channel the probe is connected to or
whether two probes are connected up. This is transmitted to the pro
cessor by a probe ID amplifier as an analog signal via the ADC.
If no probe is connected, this is detected by the probe connection comparator and dis
ables the 5V power supply to save power. The processor is informed of this by the MISO
signal being reset to zero (optoelectronic coupler under continuous current).
Page 48
GE Medical Systems EAGLE 1000 Page 48
Information Technologies Servicing Instructions 227 468 01 Rev.G
ADC operation
The ADC receives all the information and transfers the parameter readings via a
bidirectional serial interface. Although this provides a clock to operate the interface
functions, it does not provide the clock for conversion. This is obtained as a local asyn
chronous signal from a 4MHz oscillator, whose output is divided into two times 2 MHz.
PRESS amplifier
An integrated precision instrument amplifier acts as an amplifier for the pressure signaling
each channel, which amplifies the signal by a factor of approx. 200 and has an earthed
neutral over ¼ of the ADC range. A signal feedback to the input capacitors maintains the
common mode rejection.
12 Hz filter
Downline from the amplifier there is one 12V low-pass filter each. This filter is a Bessel
low-pass Grade II filter so that jumps in pressure are transferred exactly as registered.
2.2.11.2 Temp module
The circuit is shown in the block circuit diagram Temperature block diagram.
Power supply
The floating power supply for TEMP uses an HF transformer connected in parallel with
the other floating transformers, from the unregulated battery voltage. The corresponding
oscillator delivers a closed-loop controlled transformer output voltage, which may vary
somewhat depending on the load. This supplies the amplifier and the connection detector
with ±7.5 V.
The ADC and digital circuit are supplied by a voltage controller with a stabilized 5 V, in the
form of an analog and a decoupled digital power supply. When the 5V power supply drops
below 4.75 V an error signal interrupts the chip select to ADC so that no incorrect parameter readings can be transferred.
Probe detection
If no probe is connected, this is detected by the probe connection comparator with 3
threshold values, which differ between Hellige and Marquette front panel connectors,and
disables the 5V power supply to save power. The processor is informed of this by the
MISO signal being reset to zero (continuous current to optoelectronic coupler).

bidirectional serial interface. Although this provides a clock to operate the interface functions, it does not provide the clock for conversion. This is obtained as a local asynchronous signal from a 4MHz oscillator, whose output is divided into two times 2 MHz.
TEMP amplifier
An integrated precision instrument amplifier acts as an amplifier for the temperature signal, which alternately receives the measurement signal from the temperature halfbridge, two control values and a reference value for offset correction from the precision
resistor network via a multiplexer. The multiplexer is controlled along with the ADC of the
serial interface by a PAL.
2.2.11.3 Internal interfaces
Mechanical interfaces
The PCB PRESS-TEMP is plugged into the PCB ECG Monitor mechanically. The floating
power supply, i.e., the oscillator connections and the QSPI signal paths to the processor
are via this plug-through connector. This is located at the middle of the floating section of
the PCB.

Internal communication is mediated by a QSPI interface.

2.2.11.4 Interfaces to peripherals
Mechanical interfaces
There is an interface for the patient connections of the three connectable probes (2 x
PRESS, 1 x TEMP).
PRESS:
The measurement input to the two pressure amplifiers is connected floating to the front
panel via the elbow plug-in connector P1 top right along the shortest path via ferrite toroidal cores.
The single pressure input of the system with HELLIGE connectors only permits one pressure transducer to be connected directly to PRESS1. Two invasive pressures can be
measured by inserting an adapter bearing two transducer interfaces to this system input.
This can be affixed to the system using a Velcro strip.
TEMP:
The measurement input to the temperature amplifier is connected floating to the front
panel on the other opposite side via the coded left-hand plug-in connector and ferrite
toroidal cores.
Electronic interfaces
PRESS:
The PRESS channels are identified by resistor coding, even when an adapter is interposed in systems with a Marquette Hellige connector. Data transfer is on channel 1 of the
ADC.
TEMP:
In model versions with Marquette Hellige round connectors the jack plug socket is scanned for the position of the normally closed contact to detect the presence of the probe
(voltage at T/8 3/4Uz = 3.53 V (from D7) connected and 1/4Uz = 1.18 V disconnected
against approx.1/2Uz = 2.46 V as the threshold at the comparator.

2.2.12 Recorder 50 Part No. 218 111 12
Construction
The Recorder 50 is a compact module comprising a drive and drive electronics. The drive
essentially comprises 2 shells in which the DC motor-transmission-speedo unit, rubber
cylinder, thermal-array printhead, paper container with paper feed flap are assembled.
The complete drive electronics is located on the PCB Recorder 50 in the drive.
2.2.12.1 Function
The circuit setup is shown in the circuit block diagram Recorder block diagram The two
main recorder components are the printhead and the motor for paper advance.
The printhead power supply comes from the through-connected battery voltage,
increased to +22 V by a transformer.
The printhead controller acts on the printhead and the motor indirectly. It can be reset by
the host processor or by the printhead electronics.
The printhead controller acquires its data from the host processor and returns relevant
information. It acts on the printhead via a protective circuit which measures the print
head temperature and processes this. This protective circuit also receives information on
the requested heating pulse duration, which can be adjusted, and which can be modified
in accordance with the printhead temperature.
The Eagle 1000 uses only one motor speed, 25 mm/s. This is preset by the motor controller and can be adjusted.
The motor current signal MISEN, which is passed on to the host processor, is used to
protect the motor.

Electronic interfaces
Printhead interface
The thermal-array printhead is connected with a 30-lead flat strip cable to the PCB DIGITAL. Serial loading of data ensues via the KDATA cables, using the clock signal KCLOCK
into the printhead shift register. Parallel data is transferred to the printhead latch register
with the KLATCH signal. The heating period is controlled by the KSTRB cable.
The printer controller receives an analog signal, which varies according to the temperature
of the printhead, via cables TERM1 and TERM2.
Via signals delivered by the VDD1 cable when not printing the thermal-array printhead is
put into power save mode.
The remaining leads are used to supply voltage to the printhead. Refer to P-Plan PCB
Recorder for pin assignment.
Motor interface
The motor is connected to the male multipoint connector on the printer controller via a 4lead plug-in socket. The motor is connected between +22V and Motor+, the speedo generator between MOTGEN- and MOTGEN+.

4.2 Instrument performance
4.2.1 Start-up performance
After switching on, the software performs a start-up self-test. There is an internal and an
external test. Only in the event of a malfunction, in the case of the internal test, whenever
still possible, a corresponding error screen appears and an audible technical malfunction
alarm signal is activated.
Internal test:
- CPU test, internal watch dog test, LCD RAM test, RAM test, ROM CRC test and
EPROM test
External test:
- output beep (audible alarm signal test)
- output chessboard pattern on the screen
- output software version on the screen
- external watch dog test with time base test
- afterwards the power up screen appears on the display
4.2.2 Operating performance
During normal operation important system data are checked every 5 seconds. In the event
of an error this activates a warm start and the audible technical malfunction alarm signal is
activated.
4.2.3 Performance in the event of a malfunction
during start-up
After switching on, the software performs a start-up self-test. In the event of an error,
whenever still possible, one of the following messages appears on the error screen and
the audible technical malfunction alarm signal is activated:
Error in RAM, Error in ROM Error in permanent memory (EEPROM) Error in time
base Exception error during start-up Permanent start-up/shutdown error and QSPI
error.
There is now no alternative but to switch the instrument off.
In the case of a cyclic startup failure refer to 4.6 Troubleshooting tips.
during normal operation
During normal operation the working memory and backing storage are checked every 5
seconds by means of the checksum. If a malfunction is detected, this triggers a warm
start.
In the event of exceptions (deviations from normal processor operation, e.g., bus error,
address error, illegal command, division by zero, etc.) this also triggers a warm start.
Page 88
GE Medical Systems EAGLE 1000 Page 88
Information Technologies Servicing Instructions 227 468 01 Rev.G
Warm start
During a warm start the system is reinitialized and the configuration data are loaded. They
are stored in the RAM (in normal memory and backing memory) and in the EEPROM and
are protected in both cases by a checksum. Provided the checksum is correct, the data
will be downloaded from the RAM. If the test fails, testing continues in the sequence indicated above. If the data on the EEPROM are also defective, the fac
tory default data are loaded. In the event of repeated start-up/shutdown (more than twice
within 20 seconds) the error screen will appear, see above.
4.3 Battery management
Battery connection
After disconnecting and reconnecting the battery the instrument has to be started up without a power input until the battery is depleted. Otherwise, the battery is considered depleted and, depending on the actual charge, strongly overcharged.
Battery replacement
When the operating time of the instrument with a full battery is only less than 1.5 hours it
has to be replaced. The charging time to 80% capacity is approx. 3.2 hours, to 100%
approx. 12 hours.
Battery test for version V2.1 and higher
Discharge battery (switch on instrument without power line) until the audible alarm signal
sounds and the flashing message Battery appears. When this event occurs the battery
display reading is saved and after the plugging in of the power line can be seen in the
service screen. If the value is greater than 40 %, for instruments which have not been in
use for a long period, the battery can be formed by charging and depleting the battery
again. Otherwise, the battery has exceeded its service life and must be replaced.
When starting up the instrument after disconnecting the battery from the PCB ECG Monitor it must be operated without power input until the battery is depleted. Otherwise, depending on the actual battery charge, battery overcharging may occur.
* A new battery should be depleted and charged 3 times to achieve full capacity.
* To maintain the battery capacity for a long time the battery should be depleted and
charged at least once a month.

The insulating foil in the instrument serves to isolate the floating components, i.e., to ensure the required air gaps. This foil is thus of great significance from a viewpoint of safety
and must, under all circumstances be put back into the instrument when it is being reassembled. Pieces of insulating foil are located. (Where the pcb is equipped).
x under the PCB ECG Monitor
x under the PCB Oximeter
x under the PCB Press/Temp in the case of PCBs Press/Temp or Temp without isolating
foil around the PCB
x twice round the PCB PRESS/TEMP or
x around the pcb Temp
x around the power unit
4.4.2 High voltage
On the PCB ECG Monitor upper right when looking at the reverse side, next to the buzzer
is the CCFT supply for the LCD Reverse Video. In stand-by mode this generates 565 V AC
at 30 to 40 kHz. Sparking as a result of contact with this voltage causes un
pleasant burns! It is thus important to exercise caution when touching this PCB.
4.4.3 ESD protection
All instrument PCBs bear semiconductors which must be protected from electrostatic
discharge. When working on open instruments and when handling PCBs it is thus im
portant to observe the ESD safety precautions. It is especially important that service technicians always establish contact between the PCB and ground before touching a component or a cable.
When working on an open device or on PCBs use an ESD protective underlay. This
should be connected to a non-fused earth conductor potential. During battery operation
the instrument non-fused earth conductor connector must be connected to the ESD protective underlay. The service technician must be connected to the ESD protectiveunderlay
via an armband. Use an ESD protective travel bag to transport PCBs.

To remove the instrument cover undo the 4 screws on the instrument baseplate, 3 on the
rear panel and one under the handle. Remove cover. In instruments with a recorder pull
the metal plating on the recorder side slightly outward.
In instruments version V2.0 or higher with opening above the sockets on the rear panel
unscrew the two sockets for RS 232 and Nurse Call on the rear panel and push them into
the inside of the instrument.
Undo the 3 screws on the rear panel and fold this out to the back side. Disconnect the
plug coming from the power unit to the PCB ECG Monitor. For instruments V2.0 or higher
the rear panel can now be removed.
4.5.3 Removing and reinstalling assemblies
Power unit
The power unit bears an additional primary fast-acting fuse, whose rating is printed on the
PCB. To remove the board disconnect the contacts to the protective earth, the line filter
and to the PCB ECG Monitor. Undo the spring catches on the spacers and remove the
PCB Power Supply.
When reinstalling the new PCB the insulating envelope must once again be positioned
under the PCB on the spacers, with the opening facing toward the RS 232 and Nurse Call
sockets. Make sure that the connection to the PCB ECG Monitor is to the righthand connector 15VPS.
Recorder
To remove the recorder undo the 3 countersunk head screws on the instrument base and
disconnect the flat strip plug-in connector on the PCB ECG Monitor.
There are spare parts available to repair the recorder. For quick repair we recommend to
exchange subassemblies.
When reinstalling the recorder care must be taken to lay the flat strip cable correctly over
the battery.

Information Technologies Servicing Instructions 227 468 01 Rev.G
Battery
To remove the battery disconnect the plug-in connector on the PCB ECG Monitor coming
from the battery.
In instruments V2.0 or higher undo the two screws on the aluminum board over the battery, exposing the battery.
When reinstalling the battery place the two washers under the battery so that the flat strip
cables to the RS 232 and Nurse Call are not pinched (ensure that this is avoided).
Place the aluminum plate above the battery and insert both screws, so that their tips come
out at the bottom of the battery. Now place the battery upon the screw sockets to meet the
screw threads.
Attention! Fasten screws only after the threads have met. Otherwise battery isolation might be destroyed resulting in a short circuit!
Put loctite on the screw ends to avoid loosening after screwing on.
When removing the battery in instruments prior to V2.0 the two cable grips must be cut
open and the battery freed from the adhesive surfaces on the instrument baseplate.
When reinstalling the battery 2 new cable grips and 2 pieces of 1 mm thick Scotch Mount
double-sided polystyrene adhesive tape are required to ensure that the two flat strip cables do not get pinched under the battery.
When reinstalling the battery ensure that the battery connection to the ECG input side
emerges from the battery block on the left-hand side and is plugged into the left-hand
socket BATT on the PCB ECG Monitor.
When putting the instrument back into operation it should not be power-line operated until
the battery is depleted; otherwise, the battery would be overcharged.
PCB Oximeter for SpO
2
When removing this module disconnect the plug coming from the panel socket after cutting the cable grip. Hold on to the hexagonal supports (8 or 6 mm) with spring catches with
a spanner and undo the 3 screws. Disconnect the flat strip cable to the PCB ECG Monitor.
For safety reasons, when reinstalling the module make sure the insulating foil Isolation
PCB SpO2 is inserted under the PCB. Use a new cable grip to attach the cable leading to
the panel socket.
Caution! The end of the cable grip must point toward the PCB for it not to get into the
recorder gear drive.

To remove this module disconnect the flat strip connectors from the sockets TEMP and
PRESS. Undo the two nuts with the 5.5 mm socket wrench. Undo the two posidrive
screws. Pull out the PCB vertically to the PCB ECG Monitor from the middle male multi
point pass through connector.
For safety reasons, when reinstalling the PCB ensure that in versions without an insulat
ing wrapping around the floating components the insulating foil is put back under the PCB.
PCB ECG Monitor
To remove this PCB disconnect the remaining plug-in connectors. These are:
- that from the input socket ECG
- the foil strip contact to the display under the grip recess. This requires undoing the
securing mechanism by lifting the plug frame at the right and at the left and carefully
pulling out the foil strip cable
- the 4-pin socket to display back lighting
- the keypad contact to the membrane keypad next to the EPROM on the right-hand
side. Undo securing mechanism in the direction of the keypad cable.
- the flat strip cable to the Nurse Call socket
- the flat strip cable to the RS 232 socket
- the flat strip cable to PCB Oximeter SpO

Filter screen and display
Caution!
The filter screen at the front is stuck to the LCD display! Both components may be damaged during their removal. For this reason proceed as follows:
To remove the filter screen undo the two plastite posidrive screws and the hexagonal
spacers on the instrument baseplate next to the foil strip cable to the display and pull the
baseplate through the upper slits. When removing the baseplate be careful not to damage
the display foil strip cable and the cable to the backlight circuit. Using a blunt object press
firmly on both sides beyond the PCB Display on the filter screen until this becomes free
after about 30 seconds.
Now you can pull the display away towards the front after removing the 4 Plastite Philips
screws (display 930 117 17) or the 4 M3x6 screws (display 20003727-00x).
When mounting a display with a flex foil cable, fold the cable such that only about 5 cm (2
inches) protrude into the device through the aperture in the enclosure. Do not break the
cable, as this would cause a defect.
Screw the display in firmly first of all, turning the self-cutting screws in the direction they
were turned when being loosened until they click in to avoid cutting a second thread
when being tightened.
Before sticking the metal frame of the display and the filter screen degrease with alcohol
or loctite adhesive remover. Then remove the protective foil from the display. Avoid contamination with dust or fluff. Stick a new adhesive frame onto the metal frame of the display.
Place the filter screen into the recess in the casing and press down firmly.
Membrane keypad
To remove the keypad detach it with a knife applied at the corner adjacent to the filter
screen without damaging the filter screen or the edge of the casing.
Before reinstalling the keypad remove any old adhesive with petrolether. Degrease the
housing recess. Remove the protective foil from the new membrane keypad. Insert the
keypad cable through the slit in the casing. Place the keypad precisely in the casing recess and press down firmly. Avoid putting a kink into the keypad cable as this would lead
to a malfunction!

Sockets for signal inputs
Circular connectors:
To remove the sockets undo the 2 posidrive plastite screws in each case from the in
side.
When reinstalling each socket insert the wide lug upwards. In the case of the temperature
input socket direct the connections inwards and upwards. First of all, turn the selfcutting screws in the direction they were turned when being loosened until they click in to
avoid cutting a second thread when being tightened.
For instruments with sockets not attached by screws, the front panel should be replaced
when they are renewed, in this case field replacement is not recommended.
