160 Maintenance Welch Allyn Propaq LT Vital Signs Monitor Note The yellow light might flash briefly when the monitor is being inserted in the cradle or removed from the cradle. This is normal behavior and does not indicate a problem. 4. When the battery is fully charged, the green “battery charging” light is off. • Keep the monitor in the cradle whenever the patient is in bed. This keeps the monitor battery at full charge, so that it is ready for use if it must be removed from the cradle.
Directions for Use Maintenance 161 Inspecting and Cleaning the Monitor and Accessories WARNING Do not autoclave the monitor, the cradle, the AC power adapter, or any accessories. WARNING Do not immerse the monitor, the cradle, or the AC power adapter in liquid when cleaning. Do not immerse accessories in liquid when cleaning unless the accessory manufacturer’s cleaning instructions explicitly instruct you to do so. WARNING Fire and electrical shock hazard.
