8. Disassembly

Note: ESD concept; the internal circuits will be more susceptible to ESD during the

housing exchange. The construction of the internal block 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.

It is a requirement for the service personnel to observe ESD protection rules while performing service on the CFX65.
