Data is maintained by small lithium-thionyl-chloride batteries internal to the memory ICs. At the time of manufacture, no
special disposal requirements were in effect for these batteries as the amount of hazardous material contained was below
the regulated threshold. Consult your local waste disposal agency for proper disposal.
