1 Purpose

This document describes how to replace the capacitor C7.

2 Description

2.1 Devices

This section describes the prerequisites for authorized exchange of capacitor C7 on a
VitaGuard VG 300, VG 2000 or VG 3000.

Device version Serial number beginning from

VitaGuard

VG300 SN > 251 99 0001
VG2000 SN > 252 99 0001
VG3000 SN > 253 99 0016

Werner & Müller RW300 SN > 261 99 0001
RW2000 SN > 262 99 0201
RW3000 SN > 263 99 0001

Messer Medical / PX1 SN > 271 99 0001
Air Products SD1 SN > 272 99 0201
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

3.3.03 Unsolder capacitor C7.

3.3.04 Solder new capacitor C7.

3.3.05 Visually inspect soldered wires, mounting of the main board and Masimo board if
applicable. Check the position of wires and flat cables to other components and housing.
Make sure nothing is pinched or torn off.

3.3.06 The copper plate must be clamped securely before the housing is closed.

3.3.07 If both housing parts fit closely together, insert and tighten the housing screws.

3.3.08 Stick new rubber feet on the screws.

4 Functional check:

4.1 Remove the alkaline batteries from the battery compartment and then remove power
adapter during device operation. Ensure that the device outputs a permanent warning
tone.

If the test is not passed, you will work after “9204-TD-0014-Rev A-Service-Replacement
of Capacitor C7”.

4.2 Test the device according to work procedure AA30.

Please forward getemed a copy of the protocol together with the Maintenance Declaration so
that we can update our device database.

The next pages show some example pictures to help locate capacitor C7 on different main
boards.
