The AGC sets the desired output power level. This is set on
the RF Levels screen where it can be increased or
decreased by +-1% or +-10% increments. The current AGC
setting is shown in the RF Levels screen and on the bottom
banner. The display can be changed to show in Watts rather
than percent but the step size for setting the AGC will still be
in increments of 1 or 10%.
Carrier Switch:
From any screen, the FM amplifier or transmitter carrier can
be turned on or off to facilitate adjustments, settings, and
testing/troubleshooting. To toggle carrier states, simply touch
the switch icon:
The same result occurs by turning on or off the system via
the web or SNMP interface, or through controlling of the
Remote Port. A quick beep from the on-board buzzer
signifies that the response has been taken. The power
supplies and fan will remain active while the carrier is turned
off via this switch.
If additional screens, details, and settings are required, several additional
screens can be accessed through the SYSTEM SETTINGS button described
later in this section.
