Corrective Action
When all the indications have been noted, you should refer to the
following fault interpretation charts and carry out the actions detailed
against any LED whose status is abnormal. If you are unsure as to
how to undertake the actions detailed – or if several led indications
are abnormal and you are unable to distinguish between the likely
cause and affects – then seek immediate assistance from an approved
service agent.
Fault Reporting
Irrespective of whether fault rectification is successful or not, report the
fault occurrence to the nearest service agent – who will then forward
the details to the manufacturer. This type of customer feedback is an
important factor in maintaining high product reliability, and also
provides important data concerning the equipment field performance.
CAUTION
The following diagnostic charts are designed for ‘first aid’
troubleshooting only. If a problem cannot be resolved by
taking the actions given then fully trained assistance should
be sought immediately.
Do not under any circumstances make internal circuit
adjustments or interfere with the circuit boards in any other
way.
