Recharging occurs whether the monitor is on or off. While in a cradle that is connected to AC power, the monitor also receives operating power from the cradle, thus preserving battery power for use when the monitor is removed.To Recharge the Battery1. Confirm that the green “power” light (the right of two on the cradle) is on.If it is off, plug the power adapter into the cradle.2. Insert the monitor into the cradle until it clicks into place.3. Confirm that the green “battery charging” light on the cradle (the left of two on the cradle) is on.• If the green “battery charging” light is off, the monitor battery is already fully charged.• A steady yellow light indicates a problem with the battery or the cradle (contact a qualified service technician) or that the monitor is not properly seated in the cradle.Release buttonGreen: monitor is running on cradle powerGreen: battery is chargingYellow: battery or cradle fault, or monitor is not properly seated in the cradle
160 Maintenance Welch Allyn Propaq LT Vital Signs Monitor4. 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.• You can leave the monitor in the cradle when the battery is fully charged.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.WARNING Do not incinerate, submerge, crush, disassemble, or autoclave the lithium-ion battery.Caution Do not remove or replace the battery unless you are a Welch Allyn qualified service technician. Caution Do not use the monitor while the battery is being replaced.
Directions for Use Maintenance 161Inspecting and Cleaning the Monitor and AccessoriesBefore cleaning the monitor, cradle, AC power adapter, or any accessories, thoroughly inspect them. • Look for any signs of damage and any improper mechanical function of buttons or connectors. • Gently bend and flex cables, inspecting them for damage or extreme wear, exposed wires, or bent connectors. • Confirm that all connectors engage securely. Immediately report any sign of damage or malfunction to your service department. At least once per year, thoroughly inspect the cradle and the AC adapter power cord for damage or extreme wear.To clean the monitor, the cradle, or any accessories, follow these steps:1. Wipe the equipment with a cloth slightly moistened (not wet) with one of the approved cleaning solutions listed in Table 12 on page 162.2. Thoroughly wipe off any excess cleaning solution. Do not let the cleaning solution run into or accumulate in connector openings, latches, or crevices. If liquid gets into connectors, dry the area with warm air, and then check the equipment to confirm that it operates properly.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. Always unplug the AC power adapter from the electrical power outlet before inspecting or cleaning the cradle, the AC power adapter, or the monitor. Exposing any of these to liquids, such as cleaning solutions, while they are connected to electrical power could result in electrical shock or fire.Caution Use only a cleaning solution recommended by Welch Allyn for this equipment. Use of any other cleaning solutions which have a high acid content or are otherwise inappropriate can cause damage to the equipment, including cracking and deterioration of the plastic case. Caution Always follow the mixing/diluting instructions provided by the manufacturer of the cleaning solution.

Certain multifocal tachycardias can initially alarm as “low rate.”Alarm hold-off period HR/PR% SpO2RR3 seconds10 seconds5 secondsTo keep false alarms to a minimum, the monitor briefly delays or “holds off” triggering audible and visual alarms for limit violations for these vital signs. After the hold-off period begins, if the monitor detects that the vital sign has returned to acceptable limits, the monitor cancels the alarm. The next time a limit is violated, the monitor starts a new hold-off.Audio alarm hold-off with Acuity When a monitor is connected to Acuity, the audio alarms at the monitor can be delayed up to 4 minutes and 15 seconds. The delay time is selected in Acuity software at the time of Acuity installation. Visual alarm indications are not delayed.Acuity has a default audio alarm hold-off of 11 seconds.Alarms suspend When ‘alarms suspend’ is enabled, the monitor alarm tones for all parameters can be suspended on the floor for a configurable period: 90 seconds, 2 minutes, 3 minutes, 4 minutes (default), 5 minutes, 10 minutes, 15 minutes, or 60 minutes. Patient out-of-range;transmitter failureWhen a monitor is used with Acuity, an equipment alert is generated whenever the monitor fails to communicate with Acuity after a connection has been successfully established. In addition, the ‘No Acuity’ icon is displayed on the monitor.Battery failure An equipment alert is generated before the monitor battery becomes exhausted.Snapshot/event mark When is pressed, the monitor records a Snapshot. If the monitor is connected to Acuity, the monitor also sends a message to Acuity so Acuity can mark and print it. Table 18.
