Electrostatic Discharge Hazards
Electronic equipment is sensitive to static electricity. To protect these components from damage
caused by static electricity, special precautions must be taken to minimize or prevent electro-
static discharge.
Observe these safety precautions while you work with the equipment or in its vicinity.
–
Before performing maintenance or repair work, ensure that the static electricity inherent to
your body is discharged.
–
Do not wear clothing made from synthetic materials to prevent static electricity from build-
ing up. Your clothing should therefore be made of cotton or cotton mix materials.
–
Keep plastics such as vinyl and Styrofoam materials as far away from the equipment as
possible.
–
Do not remove the circuit boards from the housing of the device.
