5 Disassembly of C72
Note: ESD concept; the internal circuits are more susceptible to ESD because of the use of
exchangeable housing. 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.
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 service on the C72.

9 GRT Software: Regular Usage
Step 1: Select the section SWUpdate
Step 2: Choose the area you want to work with
•Personal Repair
Personal Repair is always accessible. Basis for the decision if a SW-Update is
authorised by Siemens is the so called Service Release-Table .
Example:
Mobile Phone has already SW50. Service -Release-Table shows SW50. In this case
SW-Update is not necessary and therefore not authorized
In any case customer data can be erased on request. (xfs and mapping have to be
activated) Of course JPICS hardware and authorisation have to be available.
•Operator SWAP
This area is only accessible if you are released by the service management to
perform SW-Updates for Net-Operators. Basis for the decision if a SW-Update is
authorised by Siemens is the so called Master-Table.
Customer data will be erased without any exception and any chance to influence by
the user. JPICS hardware and authorisation have to be available.
•Operator SWUpdate
This area is only accessible if you are released by the service management to
perform SW-Updates for Net-Operators. Basis for the decision if a SW-Update is
authorised by Siemens is the so called Master-Table.
Like in “Personal Repair” customer data can be erased on request. (xfs and mapping
have to be activated) Of course JPICS hardware and authorisation have to be
available.
