Safety Symbols; Protection Against Electrostatic Discharge (Esd) - Avaya DECT R4 Installation And Administration Manual

Safety symbols

For protection and to avoid damage to the IP-DECT system, you will find stickers with the
following symbols:
This safety symbol appears on boards which contain Electrostatic Sensitive

Protection against electrostatic discharge (ESD)

Integrated circuits are sensitive to ESD. To avoid damage caused by ESD, service engineers
and other people must handle equipment and boards carefully.
Electronic equipment has become more resistant to ESD, however, you might face situations
where static electricity can build up. Such situations are caused by an increasing application of
man–made fibres like nylon, acrylic, etc. which can generate ESD of 10,000 Volts and more.
For example, walking across a nylon carpet for a few feet can cause a person to be charged–up
to more than 10,000 Volts of ESD.
Under these conditions, you can easliy damage a a system board or a (C)MOS device by
touching the device. The device might be degraded and not totally defective, but the device
might fail at a later date without apparent reason.
To make sure that equipment and parts are well protected during shipment, special packaging
materials are utilized. System boards are shipped in anti–static bags and (C)MOS devices and
other sensitive parts in small shielded boxes.
