• Check for cracked or broken patient cable, patient leads, power cord,
communications cables, display, and enclosure.
• Check for bent or missing pins on all cables.
• Check all cable and cord connections; reseat if any connectors are loose.
Cleaning the Equipment
Monthly, or more often if needed, follow these cleaning instructions:
1. Disconnect the power plug from the AC outlet.
2. Wipe the exterior of the patient cable and electrocardiograph and with a damp cloth
using mild detergent diluted in water.
3. Use 70% isopropyl alcohol to disinfect patient cable, lead wires, and equipment.
4. Dry all components with a clean, soft cloth or paper towel.
5. Wait at least 10 minutes to allow all traces of alcohol to evaporate before turning the
electrocardiograph back on.
WARNING To ensure patient safety and proper operation, perform the
following inspections daily.
WARNING To prevent the spread of infection, the electrocardiograph and
patient cable must be kept clean, especially the components that come in
contact with patients.
Caution Do not let soap or water come into contact with the
electrocardiograph’s internal printer, connectors, or jacks.
Do not attempt to clean the electrocardiograph or the patient cable by
submersing them in liquid, autoclaving, or steam cleaning. Do not pour alcohol
directly on the equipment or soak any components in alcohol. If alcohol or liquids
spill into the electrocardiograph while cleaning, arrange to have it checked before
using it again. For Welch Allyn phone numbers, see page ii.
