Troubleshooting and Error Messages

If you are unable to transmit a stored fetal trace, having selected the appropriate Pulse or the Tone barcode, follow the steps listed below until the problem is resolved:

1.Switch on the recorder and enter the receiver-phone number.

2.Look on the recorder print-out and check the receiver phone number is correct. If it is not, follow the instructions given in the section Setting the Receiver Phone Number found in this chapter.

3.Using a telephone on the same line, call the receiver number and check if it is clear, engaged or disconnected. If there is a problem with the telephone line contact the telephone service supplier.

4.Check that the PCMCIA card modem is approved by Philips and that it and the connections between the modem and the telephone wall jack are correctly fitted in accordance with the telephone line supplier and the modem manufacturers recommendations.

5.Check the printed recorder trace to see if the correct Pulse or Tone barcode has been scanned when the Receiver Phone Number was entered (a P or a T is printed on the trace to indicate this). If the incorrect Pulse or Tone barcode has been scanned follow the instructions given in the section Setting the Receiver Phone Number in this chapter. To confirm whether the exchange you are using is Pulse or Tone, contact your telephone service supplier. Alternatively telephone the Receiver Phone Number and listen to the line being connected. If the telephone line clicks during dialing (caused by the operation of relays at the exchange) then the system is Pulse, if it makes a series of electronic sounds, then the exchange is Tone.

Transmission problems associated with the interface board raise the error message Err 532. To determine the source of any problem follow the instructions listed in

Chapter 8, “Troubleshooting Flowcharts.”

If transmission problems are due to a faulty modem card the error message Err 70 is raised. If the problem is either PCMCIA card modem or telephone line based, repair or replacement is the responsibility of the supplier.

Private phone switching systems sometimes do not use Tone or Pulse dialling. Proper operation of the remote transmission is not possible with some of these systems.
