1 Documentation and nomenclature of GE Medical Systems Information
Technologies instrument part Nos
1.1 Configuration of Instrument part No
The instrument part No comprises 8 digits, the first 6 digits determining the instrument type, the
last 2 digits the instrument version. The language is determined by configuration, thus having no
influence on the part No.
E.g. Instrument Type Version
Responder 1000, without battery, 230...240 V 101 166 01
Responder 1100, with battery, 230...240V 101 166 12
1.2 Configuration of the PCB part No
388 xxx yy Spare part numbers for the operative PCBs.
The instrument documentation, e.g., reference diagrams, circuit diagrams and parts lists are listed
under this part No.
The 388 number is located on the barcode label.
Configuration of the barcode labels:

Service Instructions
──────────────────────────────────────────────────────────────────
303 xxx yy Spare part numbers for PCBs tested especially thoroughly
303 numbers are only given to PCBs where the level of testing applied to 388 PCBs is inadequate for
implementation when servicing in the field, or where only a complete set of PCBs can be replaced in
the field.
In addition to a barcode label (388 number) 303 part Nos also have an additional label with a 303
number and are to be found in the spare parts list under this number.
389 xxx yy Replacement numbers for defective PCBs
Where servicing is required 389 PCBs are available for the replacement of some PCBs. When using a
replacement PCB (389 part No) the defective PCB is to be returned to the Freiburg factory.
Replacement PCB part Nos are included in the spare parts list.
389 PCBs have an additional adhesive label.
1.3 Instrument Status Documentation (nominal status)
Due to the hardware and software combination unambiguous documentation of the instrument
assembly status is necessary, also in the event of repairs.
This documentation comprises the following documents and measures:
Master Record Index (MRI)
This document is a component of this instrument documentation.
This document states the combination of permissible hardware and software for a particular
instrument version. The permissible PCB Index is given in the “Index” column with each update
delivered. Further permissible PCB Indexes are given in the “compatible” column. The PCB
Index can be found in the PCB barcode label.
Product Status Index
This document is created during manufacture. The Product Status Index documents the
hardware/software product status.

5 Unit Test Functions
5.1 General
After power-up and during operation, the Responder 1000/1100 runs automatic self-tests.
After power-up, the device beeps and all LED’s will briefly light up.
When the unit detects a error, the "Service" LED lights up and an acoustic signal sounds.
Every three seconds the unit try’s a new restart and test whether the error still appears.
5.2 Test Mode
The test mode is activated by inserting a jumper on PCB Responder 1000/1100 (J3 5-6). In the test
mode, some LED’s of the energy levels (2J to 30J) will indicate any detected malfunction. The
table below lists all error codes and the corresponding explanations.
If the device detects a error, then:
1.) switch Off the device
2.) insert jumper J3 5-6 (use the jumper J2 3-4 for this test)
3.) switch On the device
After power up, the “Service” LED lights up, an acoustic signal sounds and the error code will
indicated by the LED’s of the energy levels. This mode is active until the device will switched
Off.

6 Repair Notes
6.1 Safety Notes
WARNING !
Shock hazard. Before replacin
g
the
primary fuse inside the unit, alwa
y
s
switch off the unit and disconnect the
power cord.
WARNING !
Shock hazard. Always switch of the unit
and disconnect the power cord before
opening the unit. Do not reconnect the
power cord when the unit is open.
When replacing electronic components, always implement ESD protection.
Return replacement PCBs only in ESD packaging.
Return defective or exhausted batteries to the factory for proper disposal.
6.2 Component Replacement
Opening the unit
Before opening the unit switch the instrument off and disconnect power cord plug. To open the
unit, remove the 7 attachment screws on the base of the unit, place top shell to the left next to the
instrument. When reassembling the unit, make sure that none of the cables are pinched.
Replacing the PCB
The PCB is located in the top shell. With the unit open, first disconnect the plug connections
KOPOS and KONEG to the HV-capacitor. Disconnect the plug connection BATTLOAD
(only if the unit is equipped with battery). Disconnect the plug connection PADDLENEG,
PADDLEPOS, PADCONN1 and PADCONN2 to the paddles. At the Responder 1100
disconnect the remaining plugs to the keypad (plug connection KEYCONN) and to the Sync
input (plug connection SYNC). Then remove the 12 attachment screws.
Replacing the battery module
The battery module is located in the bottom shell. With the unit open, first disconnect the plug
