Introduction

This guide tells you how to install, service, and repair an Series 50 A (M1351A) and an Series 50 IP/IP-2 (M1353A) fetal monitor. Throughout this book, the M1353A is referred to as the IP-2. This also covers the IP, unless stated otherwise. It describes the system hardware and software, and tells you how to test the system and diagnose operating and service problems.

It gives instructions for both the Series 50 A and the Series 50 IP/IP-2 monitors. The features available on the monitor you are installing or servicing depend on which options have been purchased. If your monitor does not have a described parameter, you can skip that part of the instruction and move on to the next point.

Who Should The manual is for anyone who services and repairs Series 50 A (M1351A) and Series Read This Guide 50 IP/IP-2 (M1353A) fetal monitors. You must understand English and be familiar with

current conventional technical terms.

What to do	Familiarize yourself with the contents of this guide before attempting to install or service the
Next	monitor.

Repair Strategy

Reading operating error messages and the error log helps you to determine whether a fault is a hardware or software problem. Faults may be repaired by replacing a board when possible, or exchanging the monitor. Repair or replacement of components on the boards should not be attempted.

After any repairs you must carry out the following tests:

l

l

l

Performance test, by running the Self Test (see page 65).

Quick Test (see page 66).

Parameter Test (see page 68).

You must also perform the appropriate safety tests (see the section “Safety Testing” on page 100).

A series of preventive maintenance tasks and performance assurance tests must be carried out regularly to ensure the proper functioning of the monitor: these are described in “Regular Maintenance” on page 96.

Conventions and Symbols Used in this Guide

Conventions and Symbols Used in this Guide

This guide uses the following conventions for notes, cautions, and warnings:

Warning

A warning alerts you to a potential serious outcome, adverse event or safety hazard. Failure to observe a warning may result in death or serious injury to the user or patient.

Caution

A caution alerts you to situations where special care is necessary for the safe and effective use of the product. Failure to observe a caution may result in minor or moderate personal injury or damage to the product or other property, and possibly in a remote risk of more serious injury.

Note— A note calls your attention to an important point in the text.

On your monitor, this sign indicates that there is detailed information in this book which you must read before proceeding with your task

Equipotential Terminal

This symbol is used to identify terminals which are connected together, bringing various parts of an equipment or system to the same potential, not necessarily being earth potential (the value of potentials of earth may be indicated adjacent to the symbol).

Protective Earth Terminal

This symbol identifies the terminal for connection to an external protective earth.

Initial Inspection

Initial Inspection

The monitor and any supporting options ordered are supplied packed in protective shipping cartons. Before unpacking, visually check the packaging and ensure that there are no signs of mishandling or damage.

Claims for	If the shipping cartons show signs of having been mishandled, contact the carrier and
Damage	arrange for his agent to make an inspection.
	If any of the equipment supplied is damaged, you should contact both the carrier and your
	local Philips Medical Service Organization. Arrangements will then be made for repair or
	replacement, as appropriate.
Repacking	You are advised to retain the original packing carton and material. You will find it useful if it
	becomes necessary to return a piece of equipment to Philips for service. If you need to
	repack the equipment but cannot locate the original packing materials, Philips can advise
	you on alternatives.

Overview

Overview

This guide describes three different Series 50 Fetal Monitor models:

l

l

l

M1351A Single Ultrasound model (with US and Toco channels).

M1351A Dual Ultrasound Twins model (with US1, Toco and US2 channels).

M1353A model (with US1, Toco and US2/ECG channels).

The M1351A single and double ultrasound model is for external monitoring of FHR and uterine activity in the antenatal period from early gestation (approximately 20 to 25 weeks) to term. The M1353A is for monitoring FHR, including twins, maternal heart rate and uterine activity. FHR and uterine activity can be monitored externally in the antenatal period from early gestation to term, and internally throughout labor and delivery. The basic capabilities of the three models are summarized in the table below.
