Electrostatic Discharge (Esd) Warning; Operating Environment - Altigen AltiWare OE/ACC Version 5.0 Administration Manual

including an electrostatic discharge mat. Some boards have very sensitive
ceramics that contain embedded traces. These traces are very close to the
edge of the component and are easily chipped if they are hit against a hard
object or surface.

Electrostatic Discharge (ESD) Warning

Electrostatic discharge is caused by static electricity. It can damage boards
and may result in hard failures, early life failures, or cause a system to
experience intermittent, erratic behavior. Always use an ESD kit when
working on the telephony boards. The use of a special wrist strap or foot
strap (to ground the wearer to the computer's case) reduces the risk of ESD
damage.

Operating Environment

(Condiciones Ambientales de Operación/Betriebsbedingungen)
Before you set up and use the system, consider the environment in which
the system will reside:
• Choose a work surface large enough to accommodate the entire
system.
• Use a flat, stable work surface with enough space around it for proper
air circulation. For proper heat dissipation, a fan is recommended in
front of the AltiGen telephony boards to ensure sufficient airflow. Be
sure the fan filter is clean and does not block the airflow.
• Always work with grounded equipment and fixtures. The use of an
ESD mat (to dissipate static) and grounding wrist/foot straps is
necessary.
• In the manual assembly process, boards must be removed from the
anti-static bag and placed gently on a dissipative workstation mat, so
that they become discharged safely before being touched. The
dissipative mat should have a rubber upper layer and conductive
bottom layer. Regular cleaning of the mat should be done using an
anti-static mat cleaner.
The following table contains the operating specifications for the AltiGen
telephony board.
