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 signifi cantly 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, 
defi 

brillators, 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.
