ESD Notice (Electrostatic Discharge) 

Today’s electronics are electrostatic discharge (ESD) sensitive.  ESD can weaken or damage the electronics in a manner 
that renders them inoperative or reduces the time until their next failure.   Connect an ESD wrist strap to a ground 
connection point or unpainted metal in the product.  Alternatively, you can touch your finger repeatedly to a ground 
connection point or unpainted metal in the product.  Before removing a replacement part from its package, touch the anti-
static bag to a ground connection point or unpainted metal in the product.  Handle the electronic control assembly by its 
edges only.  When repackaging a failed electronic control assembly in an anti-static bag, observe these same 
precautions.
