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).
