7-4-4 Operator Panel
7-4-4-1 No Audio
• Check volume settings in the application and also in Windows.
• Use headphones, (the type that you use on a personal CD player or a laptop) to test the audio output
directly from the back of the BEP.
- If no Audio is present on the BEP, reload software. If the problem persists, replace the BEP.
- If Audio is present, follow the audio signal to the OP Panel (the audio amplifier is located in
the upper OP panel). The Audio output from the BEP goes to the Internal I/O and from there
to the OP Assembly (use an adapter to plug the headphones to the RCA outputs of the
Internal I/O). If Audio outputs are working, replace Upper OP Assembly. Otherwise replace
Internal I/O board.
- Always measure the speakers’ impedance; it should measure approximately 7 ohms. If
speakers are bad, it is possible that the amplifier on the Upper OP Assembly might be
defective, too.
7-4-4-2 No Video on LCD Display
• If the video is too dim, has dimmed areas or there is no video at all, replace the HV LCD inverter.
• Check the cabling within the system.
• If the HV LCD inverter is burnt, there is a possibility that the Digital Video Card on the PC also got
damaged; in that case you can replace the Video Card.
• Replace the Video Adapter inside the BEP.
• Replace the Back End Processor if the problem continues.
• Replace the Upper Panel Assembly.
7-4-4-3 Wrong Key Activated on the Touch Panel
• Calibrate touch panel.
• Replace Upper Panel Assembly.
7-4-4-4 Touch Panel Not Responding
• Calibrate the Touch Panel.
• Reload software.
• Replace Upper Panel Assembly.
7-4-5 Probes
7-4-5-1 Probe Recognition
• Check all the probes on all the ports. Remove all the probes, and then check each probe singly in
every port.
- If the problems persist with all the probes, replace the GRLY board.
- If only one probe fails to be recognized, replace the probe.
7-4-6 Software
7-4-6-1 Image or Patient Data Loss

of the HDD data and submit a complaint.
