8 ESD Protection
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.
It is a requirement for the service personnel to observe ESD protection rules while
performing servicing the AP75.
Reference for ESD Protection is the manual:
