Warning Signs
The following warning signs must be observed and be kept clean and
readable.
Beryllium oxide
This warning sign is applied on boards and units which contain beryllium
oxide parts.
This warning sign is applied at the bottom, inside the cabinet, below the
power supply unit.
The previous section details parts containing beryllium oxide and how to
avoid dangerous dealing with these parts.
Static Electricity
Static electricity means no risk of personal injury but it can severely
damage essential parts of the repeater, if not handled carefully.
Parts on the printed circuit boards as well as other parts in the repeater
are sensitive to electrostatic discharge.
Never touch printed circuit boards or uninsulated conductor
surfaces unless absolutely necessary.
If you must handle printed circuit boards or uninsulated conductor
surfaces, use ESD protective equipment, or first touch the repeater
chassis with your hand and then do not move your feet on the floor.
Never let your clothes touch printed circuit boards or uninsulated
conductor surfaces.
Always store printed circuit boards in ESD-safe bags.
