Electromagnetic Compatibility Compliance Statement Information
The Willow pump may be used at home, office, or other general areas. Special
consideration should be given to use:
• During Medical Procedures: Do not use the Willow pump during any medical
procedure or during imaging. For example, do not use
pump during RF ablation of a skin anomaly, x-ray, MRI, or ultrasound.
• With other Equipment: Use of this equipment adjacent to or stacked with other
equipment should be avoided because it could result in improper
operation. If such use is necessary, the pump and the other equipment
should be observed to verify that they are operating normally.
• In High Electrostatic Discharge Environments: If the air is very dry, use the pump
where floors are wood, concrete, or ceramic tile. If floors are covered with synthetic
material, the relative humidity should be at least 30%. If you notice shocks when you
touch things, as sometimes happens in very dry winter months,
be sure to touch a metal item such as a table before handling the Willow pump.
• In Industrial Settings: Avoid using the pump near arc welding equipment,
radar installations, and similar industrial settings.
• Near RF Emitters: Keep devices that use WiFi, Bluetooth, and other intentional
RF emitters at least 30 cm from the pump during operation. This includes
communications equipment peripherals such as antenna cables and external
antennas. Otherwise, degradation of the performance of the Willow pump
could result. If you know the power output the RF emitter, the table labeled
“Electromagnetic Compatibility Compliance Statement Information”
can be used for more precise information about separation distances.
