Before replacing the internal back-up battery on a device from the above list, the
employee must 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

• Silicone adhesive

By a getemed Repair Kit
(look here: 9204-TD-0012-Rev A-Service-VitaGuard General equirements)

• 10 cm self-adhesive copper strips (5 x 2 cm each)

• rubber feet

• lithium battery 3V Varta CR2430 LF

3 Work Instructions

The maintenance work for each device must be documented in the protocol “9204-TD­0013-A1-Service-Protocol for Replacement of Internal Battery”. 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 in the protocol.

3.3 Maintenance work

3.3.01
Remove housing screws

3.3.01 Remove the rubber feet and open the housing.

3.3.02 When opening the housing, pay attention to the copper strips used to improve electrical
contact between the housing halves.

3.3.02
Pay attention to
the copper stripes

3.3.05
Loosen these 4 screws

3.3.03 To prevent other hardware failures, measure the voltage of the internal back-up battery.
The voltage PWR_BACKUP is measured from positive pole of CT13 against ground. If
the measured voltage is above 3.0V, the back-up battery is good.

3.3.04 Remove jumper JU4 to break the battery circuit.

3.3.05 Loosen the motherboard with a screw driver or socket wrench, depending on how the
main board is fixed to the casing.

3.3.05
Example:
Main board
mounted with
nuts

3.3.06 The main board is connected to the housing with wires soldered to adhesive copper
strips. Remove the self adhesive copper strips from the housing in order to lift the main
board out of the housing.

3.3.06
Copper stripes

3.3.04
Jumper

3.3.07 The buzzer is connected to the motherboard with 2 wires. Unsolder the wires and
carefully raise the motherboard.

3.3.08 While raising the motherboard, pay attention to the keypad connector and remove the
connector.

3.3.09 Heat the outer ends of the solder tabs and lift off the sides. Remove the back-up battery.

3.3.09 Back-up battery with
solder tabs

3.3.10 Solder in a new back-up battery: The positive side of the battery points in the direction of
the keypad connector. Measure the battery to see if voltage is above 3.0 volts.

3.3.10 Measure voltage

3.3.11 Reconnect the keypad connector to the main board. Solder the buzzer wires back to the
solder pads on the main board.

3.3.12 Fit the main board back into the casing and solder the wires to new self adhesive copper
strips. Stick these onto the housing corners.

3.3.13 Prior to tightening the main board, align the display so that it is straight.

3.3.14 Measure the current consumption at jumper JU 4. The measured value should be less
than 30 µA.

3.3.14 Measure current

3.3.15 Attach jumper JU 14 again and secure it with silicone adhesive.

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

3.3.17 The copper strips must be clamped securely before the housing is closed.

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

3.3.19 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, replace C7 according to “9204-TD-0014-Rev A-Service­Replacement 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.
