Nautel’s service representative takes full responsibility for commissioning the transmitter, validating all
external interfaces (i.e., the ac supply, RF output, remote control and monitoring equipment) and
checking out the equipment prior to activation. The service representative turns on the transmitter,
performs all adjustments and set-up procedures, and carries out
proof of performance
tests at the site.
These tests ensure that the transmitter is operating normally in compliance with its specifications. The
service representative also provides a demonstration and a short explanation of the operation of the
transmitter. Finally, the customer signs an
Acceptance of Installation Certificate
that provides feedback
to Nautel regarding the commissioning service.
