DIAGNOSTICS
Bfore installing a new system, it is always best to set up the system on a bench to test the system
configuration. It is always easier to detect problems when the modules are together.
After installation, test the radio paths, using the radio strength testing function described later in
this section. Record the radio strength and background noise measurements for later reference
(refer section 6.2.2 for this feature). If a later test shows that the radio path has changed, this may
be the cause of a new problem.
