SX 1 Level 2 Service Manual
Note: ESD concept; the internal circuits will be more susceptible to ESD because of
the use of exchangeable housing. The construction of the internal block must be/is
designed, in the best possible way, to protect the circuit against sparks.
The keypad must be completely closed to prevent any occurrence of an ESD
disruptive discharge.
The SIM contacts may be open, thus reachable for ESD contact discharge. This
could lead to damage or destruction of the E-Gold pins.
It is a requirement for the service personnel to observe ESD protection rules while
performing servicing the M55.
