Troubleshooting Display Problems Problem No Display or Display Completely Blank. May Be Caused By Vision display is Off. Turn Vision Display On. Vision Base is Off. Turn Vision Base On. Brightness and/or Contrast controls may be out of adjustment. Adjust Brightness and/or Contrast until you can see display. Display and/or Base connections may be loose. Power down system, check all display connections. Restart system. Central Station Does Not Boot Up Problem May Be Caused By...
Problem No Communication Message Problem “NO COMM” (No communication) message. May Be Caused By... Try This... Vision Base System errors. If internal system errors occur, some error text or coded information will be displayed. Write down any such messages and contact MDE technical support for assistance. May Be Caused By... Try This... Link Auxiliary Base (LAB) is off. Turn LAB on. Connections may be loose. Power off system; check all system connections, paying particular attention to antenna.
Problem Recorder Errors Problem No recording. May Be Caused By... Try This... Bedside monitor’s antenna and or transceiver are missing and/or loose. Check connection to transceiver and antenna connection. Tighten or replace if necessary. Ensure transceiver’s LED is “on”. Check test page of monitor’s network status on RF transponder’s hex code. May Be Caused By... Try This... Recorder out of paper. Remove old paper cylinder (if present), and install new roll of paper. Paper was installed backwards.
Problem Certain events don’t record. Touchscreen Errors Problem Touchscreen is not functioning or screen response is inaccurate. May Be Caused By... Try This... ALARM RECORD device set to Printer instead of recorder. Open Hard Copy Setup popup and make sure Recorder is selected for Alarm recording. ALARM RECORD is not set on Alarm/Arr popup. Set ALARM RECORD to “ON” for event on Alarm/Arr popup. May Be Caused By Try This... Touchscreen out of calibration.
Arrhythmia Anomalies Arrhythmia anomalies can occur for a variety of reasons. Often they are traced to problems with patient electrodes, lead wires, or cables. Always ensure patient ECG signal is as clean as possible. Problem Anomalous event classifications. May Be Caused By Try This... Noisy ECG signal causing false event detection and classification due to attachment, motion, or electrical artifact. Ensure ECG signal is clean by using good setup and lead placement techniques.
Extraordinary Event Detection Problem Extraordinary Event Detection. May Be Caused By Try This... Some beats do not meet algorithms criteria for classified abnormal, even though a clinician may consider it abnormal. No action required. All arrhythmia detection algorithms must make tradeoffs to minimize nuisance alarms. No algorithm has 100% sensitivity to all abnormal beats. All beats in observed event do not meet criteria for that type of event.
Alarm, Save, Print, or Record Anomalies Problem Alarm does not sound; central station does not save, or does not record. Print Buttons do not appear on popup. May Be Caused By Try This... Arrhythmia has not been turned “on” for patient. Verify setup for patient. Ensure arrhythmia monitoring option is “on” and limits are set appropriately. Event limits are set to inappropriate values. Verify setup for patient. Ensure proper settings are “on” and limits are set appropriately.
Caring for and Maintaining Your Central Station WARNING : To avoid el ec tri c s hoc k, unpl ug the AC pow er cor d be fore cl ea ni ng CAUTIO N: Do not i mme r se the i ns tr ume nt or i ts a cc ess ories i n li qui ds.
