6 General Information

When the system is ordered from the factory the respective country option, including local
language st andards, power cords, voltage, video format and fetal paper will be automatically
allocated, apart from Canada, Belgium and Switzerland which have more than one language
option. The standard unit is delivered in the USA with 30-240 bpm paper scale selected and in the
rest of the world with 50-210 bpm paper scale selected.

The default language option for Canada is English. Option #ABC selects French.
The default lang uage option for Belgium is Dutch. Opti on #ACL selects French.
The default language option for S wi tz erland is German. Option #ABQ selects French. Option

#ACN selects Italian.

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 30 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.

n

Power-On Self Test (see page 96)
This is invoked whenever the system is switched on.

n

Performance Assurance Tests

• Parameter Test (see page 118)
This checks the processing of the signal from the transducers.

• Quick Test (seepage 119)
This checks the display, recorder and complete instrument hardware and software.

n

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 121)

• Permanent Test (see page 121)

n

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 126)

• System Test (see page 126)

• Safety Test Blocks (see page 125)

General Information 7

About the Monitor

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

n

Cardio 1/Combi for fetal heart rate (FHR) and fetal oxyg en saturatio n (FSpO2)

n

Cardio 2 for fetal heart rate

n

Toco for uterine activity

n

NPB for external blood pressure (NIBP)

n

SpO2 for maternal pulse oximetry

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

n

monitor FSpO

n

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

n

monitor maternal heart rate using ECG

n

monitor twins using either DECG and ultrasound or dual ultrasound

n

monitor uterine activity (Toco) externally or internally

n

detect fetal movements (FMP) using ultrasound

n

measure maternal blood pressure externally

n

measure maternal pulse oximetry

n

display maternal ECG waveform and record “snapshot” ECG waveform.

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 P lus P ackage signal processing technique used by the instrument ensu res that the
information provided by the monitor is very accurate. Ultrasound FHR traces are comparable with
direct ECG FHR traces and variabi li ty r ec o rded in the ultr aso und m od e is almost identical to t hat
recorded in the DECG mode.

The recorder uses a high resolution thermal array print h ead which give s a very reliable and good
quality trace. Automatic annotation capabilities include time, date, paper speed and monitoring
methods. Nursing not es 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 fea ture, and the delay between
changing the se tting and seeing the cha n ge 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. Thi s ale r t ackn ow led g ement 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 (approxima tely 10 seconds) or lon ger period (approx imately 50 second s). The times var y according to
the heartrate and signal quality and those quoted here are val i d f or go od 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 mo r e e a sily. Fast response m o d e is indicated on the trace by .

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 sp eed wil l r e sul t in a chang e in the app earance
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

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

2. Turn the monitor on.

3. Check that the paper speed, and time and date are configured.

4. With no transducers connected, press .
You should see the following:

DISPLAY: All parts of the display are lit followed by all mode symbols. These will flash
alternately for about 10 s econds.

RECORDER: During the test the recorder speed will automatically set to 3cm/min and a
test pattern will be printed on the recorder paper to verify the condition of the thermal print
head and if the printer is correctly configured. See Figure 10-1. Recorder Test Pattern, for a
sample recorder test pattern.

This chapter tells you how to upgrade the monitors, which options require which steps, and how
to restore the monitor’s original configu ration. Many of the upgrade option s (especially those
whose option number begins with “C”) require very similar steps to upgrade them, as you will see
from the tables.

1. Check the monitor’s serial number as described in the section on “Instrument Identification”
on page 1-6.

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 Chapter10, “Safety,
Maintenance, and Calibration.”

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 config uration. See page 30 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.

To remove the power supply from the monitor:

psm20sca.tif

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 supply.

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 t he n ew one. The t echni que for r em oval and replacement is
the same for all of the boards. These boards are:
