1.2.2 WARNING – The unit is sensitive to ESD.
Description
ESD (electrostatic discharge) is the transfer of electrostatic charges between two
objects with varying charges, either through direct contact or through an electrical
field.
The discharge contains very little electricity and is therefore not hazardous to
humans, however, electronics can be damaged by the high voltages.
Elimination
Location of attachment point for ESD bracelet
