LIFE SUPPORT POLICY

This important safety information applies to all Wavelength 

electrical and electronic products and accessories:

As a general policy, Wavelength Electronics, Inc. does not 

recommend the use of any of its products in life support applications 

where the failure or malfunction of the Wavelength product can 

be reasonably expected to cause failure of the life support device 

or  to  significantly  affect  its  safety  or  effectiveness.  Wavelength 

will not knowingly sell its products for use in such applications 

unless it receives written assurances satisfactory to Wavelength 

that the risks of injury or damage have been minimized, the 

customer assumes all such risks, and there is no product liability 

for Wavelength. Examples of devices considered to be life support 

devices are neonatal oxygen analyzers, nerve stimulators (for 

any  use),  auto-transfusion  devices,  blood  pumps,  defibrillators, 

arrhythmia detectors and alarms, pacemakers, hemodialysis 

systems, peritoneal dialysis systems, ventilators of all types, and 

infusion pumps as well as other devices designated as “critical” 

by the FDA. The above are representative examples only and are 

not intended to be conclusive or exclusive of any other life support 

device.
