First, verify that the electrodes are properly placed and making good contact with the skin; check for loose connections or dried gel. Ensure the leads are plugged into the correct ports on the monitor. Try replacing the lead wires or the electrodes. Check the battery polarity and ensure it is inserted correctly. If the monitor has a test mode, use it to verify signal detection. If the flat line persists, try a different monitor. Document the issue and the troubleshooting steps. If the problem cannot be resolved, reschedule the patient and report the equipment malfunction.

The technician should educate the patient on proper wear and care: keep the monitor dry, avoid rough activities, and keep a diary of symptoms and activities. Confirm that the electrodes are secure and the skin is clean and dry. Use additional tape if needed to secure leads. Verify that the monitor is recording by observing the display or listening for beeps. Provide a contact number for questions. At the end of the monitoring period, review the diary and ensure the data is complete before removing the monitor.
