indicates the electrostatic sensitive area. When operating the equipment in this area,
Do not touch the device with bare hands to avoid damaging the electrostatic sensitive
devices (ESSDs) on the circuit board.
The electronic line is very prone to electrostatic damage. Wear the ESD-preventive wrist
strap, ESD gloves, and ESD-preventive clothes properly when handling hard disks,
especially bare hard disks. Hold only the edge of the hard disk.
Since an ESD-preventive wrist strap prevents only the static electricity of your body, you
need to wear an ESD-preventive coat to prevent the static electricity of the clothes.
Wear the ESD-preventive wrist strap, ESD-preventive gloves, and ESD-preventive clothes
before installing or replacing the device. Otherwise, the static electricity of your body may
damage the ESSDs on the circuit board.
Use special ESD-preventive bags to carry or transport the parts.
