This section provides a step-by-step description of equipment installation and
configuration procedure. Follow these procedures closely upon first power-on
andeachtimeanychangeismadetogeneralconfiguration,suchaswhenanew

Oncethedesiredconfigurationhasbeensetup,nomoresettingsarerequired
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial configuration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and firmware features and
capabilities.Pleaseseetherelevantsectionsforadditionaldetails.

IMPORTANT:When configuring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
