Section 5 - Initial Activation

1. Overview

After finishing the installation, the equipment is ready to be activated. It is important to observe that the
transmitter is configured at the factory with the parameters that were supplied by the customer at the time
he made the purchase, such as the channel output, power, MER, etc.
One should check the functionality and performance of the RF power, DC currents, temperature, alarms,
and communication.
Never turn on the equipment without connecting it to an Antenna or RF Load, as this may
cause serious damage to the Equipment.
You must ensure that the general circuit breaker is off. Then, ensure that the all POWER
ON / OFF settings are set to the OFF position in all Drawers.
Make sure that the Channel is configured and the Exciter is the same as the Mask Filter
and the antenna.
Check if the Antenna VSWR for the operating channel is better than -23dB of Return Loss.
Using a voltmeter, check that the AC Mains of the equipment is within its characteristics.
