SD2 SN > 273 99 0001
Before replacing capacitor C7 on a device from the above list, please check the current
device status (firmware and hardware version).
Checking the current device status
To ensure the device status is up to date, the following needs to be checked:
Status Device version PC/ECG connector
EPROM V3.1.0 All Metal / 8 pin or 14 pin
EPROM V3.3.0 All B678 plastic / 14 pin
If the firmware is below V3.1.0, please contact getemed’s technical service to clarify the
current device status.
2.2 Required tools
The following tools are required:
• Phillips screwdriver PZ1
• Phillips screwdriver PH1
• Hexagonal socket wrench SW 5,0
• Soldering iron
• Digital multimeter

2.3 Required materials
The following materials are required:
• Tin solder
• Unsoldering wick
By a getemed Repair Kit
(look here: 9204-TD-0012-Rev A-Service-VitaGuard General equirements)
• 4 rubber feet
• 1 capacitor C7 (SMD 0805, 2.2 nF)
3 Working steps
If operational test reveals that no alarm signal is emitted upon power failure, capacitor C7
must be replaced. The maintenance work must be documented for each device in a
protocol “9204-TD-0014-A1-Rev A-Service-Protocol for Replacement of Capacitor C7”.
After maintenance work is completed, a copy of the protocol shall be sent to getemed AG.
3.1 Device type
The device type is read from the label. Tick the appropriate device type in the protocol.
3.2 Serial number
The serial number is read from the label and entered into the protocol.
3.3 Maintenance work
3.3.01 Remove the rubber feet and open the housing.
3.3.02 When opening the housing, pay attention to the copper plate
