Introduction
This Service Guide contains technical details for the Avalon FM20 and FM30 fetal/maternal monitors.
It provides a technical foundation to support effective troubleshooting and repair. It is not a
comprehensive, in-depth explanation of the product architecture or technical implementation. It offers
enough information on the functions and operations of the monitoring systems, so that engineers who
repair them are better able to understand how they work. It covers the physiological measurements
and the monitor hardware that acquires and displays them.
The Avalon FM20/FM30 Fetal Monitor Service Guide supplements the maintenance and
troubleshooting procedures, carried out by the operator that are described in the Instructions for Use.
Refer to the Instructions for Use for maintenance and troubleshooting procedures that may be
performed during normal operation.
Only qualified and authorized service personnel should attempt to install the system, disassemble the
monitor, remove or replace any internal assemblies, or replace the transducer cable or belt buttons.
For detailed information concerning the configuration of the fetal monitor see the Configuration
guide.
