Introduction
This part of the Maintenance section covers maintenance tasks that include schedule maintenance,
dismantling and assembly instructions and fault finding. Due to the complexity of most modules the
recommended policy is repair by replacement of the radio. However module replacement information is
supplied in the event that Park Air Customer Support advises this may be done.
A faulty module may be traced by aid of the front panel LCD and Scroll/Select control; VFP or MARC.
Note ...
Access to a PC is essential when fitting spares.
During all maintenance tasks the warnings and cautions given in this section should strictly be adhered to.
For maintenance purposes and loading new software, a Virtual Front Panel (VFP) is used. The VFP is a
standard PC loaded with a bespoke software package for carrying out these tasks. Separate VFP
operational instructions are included in Part 3 of this section of the document.
