General Information

About this Guide

Who This Guide is For

What to do Next

This guide tells you how to install, service and repair a Series 50 XM Fetal/Maternal monitor or a
Series 50 XMO Fetal/Maternal monitor. It describes all the system hardware and software, and
tells you how to test the system and diagnose operating and service problems. It also tells you what
upgrade paths are available and how to follow them.

It gives instructions for both a Series 50 XM Fetal/Maternal monitor and a Series 50 XMO Fetal/
Maternal monitor. The features available on the monitor you are installing or servicing depend on
which options have been purchased. All instructions apply to a fully equipped monitor. If your
monitor does not have a described parameter, then you can ignore that part of the instruction and
skip to the next point.

The illustrations in this book show the Series 50 XMO Fetal/Maternal monitor, with the fetal

pulse oximetry

This guide is for technical personnel installing and servicing the monitor. They must have a good
understanding of medical equipment installation procedures. Conventional current technical
terms are used throughout this guide. Familiarity with such terms is assumed.

Familiarize yourself with the contents of this guide and the Instructions for Use before attempting to
install or service the monitor.

Philips uses a two-section serial number (“XXXXGOOOOO'') for instrument identification. This
is located on labels attached to the monitor. One label is on the right side of the monitor, the other
label is identical and attached to the base of the monitor. The first four digits are the Serial Prefix
Number, and identify the modification standard of the instrument. The last five digits are the
Serial Number of the instrument. The letter that separates the serial prefix and suffix designates the
country in which the instrument was manufactured, “G'' = Germany.

Service Philosophy

Any errors produced are marked on the trace paper with the symbol and a specific error
message is shown on the monitor display. In addition, the errors are reported on the system error

log (see page 24 for instructions on how to print the error log). Read the error messages and system
error log to determine whether the fault lies in the hardware or firmware. These problems can be
repaired by board replacement or unit exchange. Do not attempt component-level board repair.

Overview of the Service Tests

The system contains resident tests to enable monitoring of system status and errors that occur.

" Power-On Self Test (see page 112)

This is invoked whenever the system is switched on.

" Performance Assurance Tests

• Parameter Test (see page 112)
This checks the processing of the signal from the transducers.

• Quick Test (see page 114)
This checks the display, recorder and complete instrument hardware and software.

" Service Tests

These are invoked by connecting the monitor to a PC and using a software service tool to
assess, test and configure the system.

• Cyclic Test (see page 116)

• Permanent Test (see page 116)

" Safety Tests

These test the electrical safety of the monitoring system and must be carried out after
upgrades and repairs. You must use a safety testing tool.

• Instrument Safety Test (see page 120)

• System Test (see page 120)

• Safety Test Blocks (see page 119)

6 General Information

About the Monitor

The monitor has five color- and mechanically-coded input sockets:

" Cardio 1/Combi for fetal heart rate (FHR) and fetal oxygen saturation (FSpO

" Cardio 2 for fetal heart rate

" Toco for uterine activity

" NPB for external blood pressure (NIBP)

" SpO

for maternal pulse oximetry

2

)

2

When a transducer is connected, the monitor automatically selects the correct operating mode.
The unit can:

" monitor FHR using both direct ECG (DECG) and ultrasound (US)

" monitor maternal heart rate using ECG

" monitor twins using either DECG and ultrasound or dual ultrasound

" monitor uterine activity (Toco) externally or internally

" detect fetal movements (FMP) using ultrasound (optional)

" measure maternal blood pressure externally (optional)

" measure maternal pulse oximetry (optional)

" display maternal ECG waveform and record “snapshot” ECG waveform (optional)

" monitor FSpO

(optional)

2

A series of error messages appear in the instrument's display if certain measurements cannot be
carried out. Built-in check facilities give you a greater monitoring confidence because most of the
instrument functions can be checked quickly and easily.

The Performance Plus Package signal processing technique used by the instrument ensures that the
information provided by the monitor is very accurate. Ultrasound FHR traces are comparable with
direct ECG FHR traces and variability recorded in the ultrasound mode is almost identical to that
recorded in the DECG mode.

The recorder uses a high resolution thermal array print head which gives a very reliable and good
quality trace. Automatic annotation capabilities include time, date, paper speed and monitoring
methods. Nursing notes can also be documented using an optional barcode reader.

Either of the monitors can be upgraded to include all parameters, depending on availability within
the country of purchase.

1. To find the correct setting, connect a Toco transducer to the monitor and then change the setting until the
trace is recording 20 units on the paper. Because of the 8-second time-out feature, and the delay between
changing the setting and seeing the change on the paper, you may have to repeat this procedure to set the
offset.

2. If the alert acknowledgement function is on, the fetal monitor adds the alert acknowledgement function on
the recorder marker button. This alert acknowledgement is given only to the central station after a request
from the central station (communication is via the digital interface.)

3. With this setting you can switch the control between the RS232 port on the new Telemetry/System board
M1350-66536 and the RS422 port implemented on the System Interface board M1350-66532. If only one
of them is built into the fetal monitor this one will be active regardless of the setting.

4. Response mode is an output-average filter. You can select whether the monitor averages samples over a short
time (approximately 10 seconds) or longer period (approximately 50 seconds). The times vary according to
the heartrate and signal quality and those quoted here are valid for good signal quality and a heartrate in the
120 bmp range. The fast response mode, because it requires fewer samples, allows you to see sudden changes

in output more easily. Fast response mode is indicated on the trace by .

6. Press and release to return to the normal display.

You can also change the format of the time and date using the optional Barcode Reader and the
feature setting barcodes supplied with it.

Getting Started (Basic Considerations and Operation) 39

Changing the Time Format

To change from 12-hour to 24-hour format, enter
TIME FORMAT 24H (MILITARY) from the feature setting sheet.

To change from 24-hour to 12-hour format, enter
TIME FORMAT AM/PM from the feature setting sheet.

To change from Day.Month.Year to Month/Day/Year format, enter
DATE FORMAT NORTH AMERICAN from the feature setting sheet.

To change from Month/Day/Year to Day.Month.Year format, enter

DATE FORMAT EUROPEAN from the feature setting sheet.

If the batteries are not changed when they become low or empty of charge, the settings will return
to their default values: the date is set to 04.04.44 and the time is set to either 00.00 (European
Format) or 12:00A (US Format).

Setting Paper Speed and Scale

Setting the Paper Speed

The paper speed can be 1, 2 or 3 cm/min. The default for North America is 3 cm/min; the default
for other countries is 2 cm/min. A change in paper speed will result in a change in the appearance
of an FHR trace, care must be taken to ensure ALL monitors in your institution are consistently
set at the same speed.

The ACOG technical bulletin on FHR monitoring states that “accurate pattern recognition is
difficult if not impossible at 1 cm/min and that 1 cm/min is only recommended for more
economic screening. When FHR abnormalities arise, the faster paper speeds will enhance FHR
pattern recognition.”

Use the Paper Speed Key to display the current paper speed and to return to the normal display.
You also return to the normal display automatically if you don't press any key for a few seconds.
When you return to the normal display, the new paper speed is set, and the time, date, speed and
monitoring modes are printed on the paper.

To set the paper speed:

1. Press and release to display the current speed.

2. Press or to set the speed.

3. Press and release to return to the normal display.

Caution
Using recorder paper that is not approved by Philips can damage the monitor. This type of
damage will not be covered by warranty.

Some monitor configurations come with a fetal monitoring record (FMR) management system.
Included in the FMR system are labels that facilitate a total management system for organized
storage and retrieval of patient records.

If you wish to use paper with a different FHR scale (for example, 50 - 210 bpm instead of 30 - 240
bpm) you can change the paper scale settings:

1. Using the service software (see “Using the Service Program” on page 30).

2. Using pushbuttons (see “Configuring the Monitor Using Pushbuttons” on page 21).

Note If an OBMS Board (M1350-66532) is plugged in at the same time as the Combined Telemetry/

Digital System Interface Board (M1350-66536), the digital interface on the Telemetry Board is
switched off as per default. See Chapter 5 for information on how to activate RS232.
If the Software Revision installed is earlier than A.04.01 the RS232 system interface will remain
inactive.

System Interface Option J12

The system interface is provided for connection to the Obstetrical Display Information System
(ODIS), and the Obstetrical Information Management System (OBMS) Central Stations.

The pin allocations for the various signals are shown below.

Figure 5-8 System Interface Connections

The following table lists the pin numbers, the signals at each pin and the signal details. If a
Telemetry/System Interface M1350-66536 is connected at the same time, you should check the
correct setting of C13. See Chapter 5 for the correct setting.

Initial Inspection

The upgrades are supplied packed in protective shipping cartons. Before unpacking, visually check
the packaging and ensure there are no signs of mishandling or damage. Using the table above,
ensure that you have received the correct components for the upgrade option number, check that
the contents are complete and that you have the correct upgrade.

Claims for Damage

Follow the instructions in the section “Unpacking and Checking the Shipment” on page 3 if the
shipping cartons show signs of damage.

What You Need

Upgrading a monitor requires simple tools:

" pozidrive screwdriver size 1
" safety test equipment
" PC for configuration
" Configuration software “pegserv.exe”
" Cable to link PC to fetal monitor

Before You Start

Warning
Disconnect the electrical power to the monitor before you remove any component. Follow

the necessary electrostatic discharge (ESD) procedures throughout the upgrade process.

Instruction 1 Verifying Monitor for Upgrade

Before you start the upgrade process, ensure that you are upgrading the correct monitor and that it
is working properly.

Options Requiring this Procedure

C01 C02 C03 C04 C30 C31 C32 C33 C34 C35 S01 J10 J12 J13

--

!!! ! !!!!!!!!

1. Check the monitor’s serial number as described in the section on “Instrument Identification”
on page 5.

When you have upgraded the monitor, remove the old serial number labels from the
monitor and replace them with the new labels supplied in the upgrade pack.

2. Ensure that the monitor you are about to upgrade works correctly. Perform a Quick Test
and a Parameter Test on the monitor. These are detailed in Chapter 9.

If the monitor does not successfully complete its service tests, do not upgrade it. Make
appropriate arrangements for its repair. It is more expensive in time and money to
troubleshoot after an upgrade.

Instruction 2 Checking Current Configuration

The first step in the upgrade process for all upgrade options is checking the current configuration.
You do this by printing the error log to provide you with a record of the current configuration.
After you have finished upgrading the monitor, you will need this record to help you to restore the
initial configuration. See page 24 for instructions on printing the error log.

Instruction 4 Using the New Base Assembly

When you upgrade a Philips Series 50 IX monitor, you receive a new base unit that is fully fitted
with the options that were ordered. All you have to do is transfer some components from the
original monitor into the new base unit and perform a firmware upgrade. From the original
monitor, you must reuse the cover, the power supply, the recorder and the ROM board.

72 Upgrades

1. Undo the four screws at the rear of the power supply.

2. Pull the power supply out of the rear of the monitor.

3. Put the power supply into the new card cache of the upgrade kit. This is basically a reversal
of the above procedure. Hold the ON/OFF switch (on the front of the monitor) as this can
be dislodged while inserting the power supply. If you have trouble locating the power supply
into the rear of the monitor, remove and check that the pins connecting the supply to the
backplane are not bent. Reinsert the power supply (see page 14 for the correct location).

Reusing
Boards

Depending on the configuration of the original monitor, you may have to swap up to three other
boards from the original monitor into the new one. The technique for removal and replacement is
the same for all of the boards. These boards are:

" Telemetry interface

" Dual serial interface

" OBMS interface

1. Undo screws (1) and (2) at the top and bottom of the board.

2. Move lever (2) upwards and pull the board out of the rear of the monitor.

Restoring

Settings Using
Pushbuttons

!!! ! !!!!!

1. If you have not yet done so, print the error log (see “Printing and Clearing the Error Log” on
page 24). This will serve as a useful record of the current monitor configuration.

2. Enter the new serial number from the serial number labels (included in this upgrade kit).
This must be done using the service software: see “Writing the Serial Number” on page 36
for instructions. A serial number can be written only once to the exchanged board. If you
accidentally confirm an incorrect serial number you can reset it using an access code
obtainable from your Philips Response Center.

3. You will be prompted for the option configuration. You can set all the option settings using
the pushbuttons, as described in “Writing the Serial Number” on page 36. Using the error
log you printed previously, ensure that you restore only those options that the customer had
before you commenced the upgrade.

4. Double check the settings carefully. If you accidentally confirm an incorrect serial number
you can reset it using an access code obtainable from your Philips Response Center.

5. Step back to the main menu of the service program and select “Configuration Tasks” to set
the paper speed, time format, and so forth, or perform the self tests, or read the error log.
You will find detailed instructions for all these tasks in Chapter 3, “Configuring the
Monitor.”

Using the data from the error log you must now restore the customer’s original service settings. Of
course, if you have added new functionality, you should ensure that default settings for the new
parameter(s) are satisfactory for the customer and if not, change them. See “Configuring the
Monitor Using Pushbuttons” on page 21 for instructions on changing the settings.
