Solutions identified for identified hazards:

Foreseeable misuses:

Wireless communication:

• RF communications should be encrypted and/or authenticated to prevent attacks, and a possibility for frequency-hopping should be explored to avoid incidental or deliberate interference.

Changes that may occur during lifetime:

Battery degradation:

• Battery circuit should be within safe voltage/current regulation circuit, with precautionary shut-down available.

Overheating:

• Temperature sensors should monitor for overheating and shut-down before hazardous temperatures can be reached. Good ventilation should be implemented in design.

Disposal after lifetime:

Correct disposal/recycling instructions should be included with package, including clearly visible warnings. A potential take-back program should be considered to accept products back.
