5. FAULT FINDING LOG
You will always be asked for this report:
●when requesting technical assistance from the Techline.
●for approval requests when replacing parts for which approval is obligatory.
●to be enclosed when returning monitored parts on request. The log is needed for warranty reimbursement, and
enables better analysis of the parts removed.
6. SAFETY ADVICE
All work on components requires that the safety rules be obeyed to prevent damage or injury:
–Make sure the battery is properly charged to avoid damaging the computers with a low load.
–Use the appropriate tools.IMPORTANT:
Any fault on a complex system requires thorough fault finding with the appropriate tools. The FAULT
FINDING LOG, which should be completed during the fault finding procedure, ensures a record is kept of
the procedure carried out. It is an essential document when consulting the manufacturer.
IT IS THEREFORE COMPULSORY TO COMPLETE A FAULT FINDING LOG
EVERY TIME A FAULT FINDING PROCEDURE IS PERFORMED.
