ENVIRONMENTAL ISSUES
Manufacture Stage• Use of tin/lead and other chemicals in the production of the PCB’s.• Various chemicals used to create the design’s components (LCD,
Microcontroller, Multiplexers, etc.).
Normal Use Stage• ON: Not more than 100mA.• Stand-by: Less than 30mA• OFF: No power consumption.
Disposal/Recycling Stage• Proper processing of PCB and Integrated Circuit components to
ensure safe disposal/recycling of non-biodegradable and hazardous materials.

ETHICAL ISSUES
Failing Parts• TI Microcontroller, Codec, LED’s and analog
components, might fail over time.• All circuit components and additional peripherals
used when testing might be damaged if not compatible.
Safety Concerns• Overheat of voltage regulators may lead to
combustion of packaging or other circuit parts (Highly unlikely).

SUMMARY
Environmental Issues• Use of chemicals.• No more than 100mA when ON and less than
30mA on Stand-by mode.• Safe Disposal/Recycling of electrical components.
Ethical Issues• Parts might fail overtime or if misused.• Combustion (i.e. Fire).
