    Environmental Compliance Waste Electrical and Electronic Equipment (WEEE) Directive GE Measurement & Control is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back initiative, directive 2012/19/EU. The equipment that you bought has required the extraction and use of natural resources for its production. It may contain hazardous substances that could impact health and the environment. In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of the materials of your end life equipment in a sound way. The crossed-out wheeled bin symbol invites you to use those systems. If you need more information on the collection, reuse and recycling systems, please contact your local or regional waste administration. Visit http://www.ge-mcs.com/en/about-us/environmental-health- and-safety/1741-weee-req.html for take-back instructions and more information about this initiative. TransPort® PT878 User’s Manual v
