Safety summary
Welch Allyn Micropaq Monitor
Electrostatic discharge (ESD)
CAUTION
SENSITIVE ELECTRONIC DEVICES DO NOT SHIP OR STORE NEAR STRONG ELECTROSTATIC, ELECTROMAGNETIC, MAGNETIC OR RADIOACTIVE FIELDS
ATTENTION OBSERVE PRECAUTIONS FOR HANDLING
ELECTROSTATIC SENSITIVE DEVICES
WARNING Electrostatic discharge (ESD) can damage or destroy electronic components. Handle static-sensitive components only at static-safe workstation. WARNING Assume that all electrical and electronic components of the monitor are static-sensitive. Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accumulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few. Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are static-sensitive and handle them accordingly. •
Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.
•
Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations-a properly grounded table and grounded floor mat-and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.
•
Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.
•
Remove or insert static-sensitive components and assemblies only with monitor power turned off.
•
Insert and seal static-sensitive components and assemblies into their original static-shielding bags before removing them from static-protected areas.
•
Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies from their protective bags and before beginning any disassembly or assembly procedures.

Indicators Visual Alarm indicator Green
Flashes slowly during normal operation.
Red
Flashes during patient alarm. Remains on continuously when alarms are silenced or suspended.
Yellow
Flashes during an equipment alert and while the monitor is not connected to the network. Remains on continuously if the operator suspends an alert at Acuity for 90 seconds or acknowledges (dismisses) a low battery alert from the monitor or Acuity.
Note
Flashing green indicates that the monitor is connected to the network but not necessarily connected to a patient. If the monitor is actively monitoring a patient, continuous green indicates that no alarms or alerts are detected.
Audible Alarm indicator Beeps to indicate a patient alarm, and beeps faster for life-threatening arrhythmia alarms. Beeps when the equipment needs attention. This beep tone is slower than the patient alarm tones. Volume can be configured at Acuity as high, low, or off. Volume can be configured at Acuity for network connection or for when communications with the FlexNet network are interrupted.
Controls Snapshot key When connected to Acuity, pressing this key sends a snapshot of the patient’s numeric and waveform data to the Acuity Central Monitoring System. Depending on how Acuity is configured, this will cause Acuity to print a 21-second snapshot (14 seconds of history, 7 seconds of data after the button is pressed) to the Acuity central station printer. Note
Snapshot is the default selection of the monitor. However, the connected monitor will inherit the configuration previously defined by Acuity. For example, if Acuity has defined the Snapshot key to respond with a Nurse Call function and a new monitor is introduced to the system, the Snapshot key definition will remain as Nurse Call. For more information about using the Acuity Central Monitoring System, refer to Acuity Directions For Use (810-1605-XX)
