Chapter 7 - Replacing Parts
Replacing Parts
This chapter identifies the boards and replacement parts, giving their part
numbers, and lists the tools you’ll need to service the Series 50 T Fetal
Telemetry System.
For most service tasks, it is not necessary to remove parts, and you should
only dismantle the Telemetry Receiver and Transmitter as far as is necessary.
Warning
Electrical power is dangerous. Before removing any parts from the
Receiver, the power to the Receiver must be disconnected.
Caution
Static electricity will damage sensitive electrical circuitry. Ensure you are
adequately grounded before touching any circuit board or its associated
components.
Ordering Parts
To order a part, contact your local Philips Sales/Service Office, quoting the
part number listed in the tables. To order a part not listed in the tables, give
the following information:
• The model number of the Telemetry System.
• The complete serial number of the Telemetry System.
• A description of the part, including its function and location.
Caution
Occasionally, as well as markings indicating manufacture by Philips,
electronic components will carry standard commercial identification
numbers. These components have been selected to meet specific
operational criteria. Using components purchased through normal
commercial channels may result in degradation of the operation
performance or the reliability of the Receiver or Transmitter.
