Antistatic Precaution
ACM devices contain electronic components;
take all necessary antistatic precautions
including:
1) Before handling an ACM device
touch an exposed earthed surface to
discharge any body static.
2) Always store in an anti-static
container or package; never place
on a non anti-static surface.
3) Handle the device by the edges;
never touch the electronic
components on the device.
