Handling PC boards
The PC boards contain components that are
highly sensitive to static electricity.
Those who come into contact with circuit
boards containing sensitive components
must take certain precautions to avoid
damaging the components (ESD protection).
When working with ESD sensitive compo-
nents, always use a grounded wrist band
and grounded work surface. Adequate
service tools must also be used.
PC boards (spare or exchange parts) must
always be kept in protective packaging for
sensitive electronic device.
PC boards must not be inserted or removed
while the mains power or battery power is
applied to the PC boards.
Remove and insert the PC boards very
carefully to avoid damage to the connectors.
