However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by simply turning the equipment off and on, the user is encouraged
to try to correct the interference with one or more of the following ways:
•
Reposition the receiving antenna.
•
Increase separation between the equipment and receiver.
•
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•
Consult the dealer or an experienced radio/TV technician for assistance.
Labels and symbols are displayed on the device as shown in the following images:
1.5.4
(ESD) Electrostatic discharge sensitivity symbol
WARNING
Pins of connectors identified with the ESD warning symbol should not be touched and the connections should not be made
to these connectors unless ESD precautionary procedures are used.
Precautionary procedures are the following:
•
Environmental procedures as: air conditioning, humidification, conductive floor coverings, non-synthetic clothing
•
User procedures as: discharging one's body to a large metal object, using wrist strap connected to earth.
It is recommended that all staff involved receive an explanation of the ESD warning symbol and training in ESD precautionary
procedures.
the electrostatic discharge is defined as an electric charge at rest. It is the sudden flow of electricity between two objects caused by
contact, an electrical short, or dielectric breakdown. ESD can be caused by a buildup of static electricity by tribocharging, or by
electrostatic induction. At lower relative humidity, as the environment is drier, charge generation will increase significantly. Common
plastics generally will create the greatest static charges.
Typical electrostatic voltage values:
Walking across a carpet
Walking over untreated vinyl floor
Vinyl envelope used for work instructions
Worker at a bench
If two items are at different electrostatic charge levels, as they approach one another, a spark or Electrostatic Discharge (ESD) can
occur. This rapid, spontaneous transfer of electrostatic charge can generate heat and melt circuitry in electronic components.
A latent defect can occur when an ESD sensitive item is exposed to an ESD event and is partially degraded. It may continue to perform
its intended function, so may not be detected by normal inspection. Intermittent or permanent failures may occur at a later time.
Static dissipative material will allow the transfer of charge to ground or to other conductive objects. The transfer of charge from a static
dissipative material will generally take longer than from a conductive material of equivalent size. Some well known insulators are common
plastics, and glass. An insulator will hold the charge and cannot be grounded and conduct. the charge away.
Both conductors and insulators may become charged with static electricity and discharge. Grounding is a very effective ESD control
tool, however, only conductors (conductive or dissipative) can be grounded.
The fundamental ESD control principles are:
•
Ground all conductors including people
•
Remove insulators, substitute with ESD protective versions
•
neutralize with ionizers
•
ESDS outside the EPA (ESD protected area) to be in packaging having ESD shielding property
