Appendix A Modem Interface Module 167
If you are unable to transmit a stored fetal trace, having selected the appropriate Pulse or the
To ne 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.
