Main FM Screen
The Main FM Screen summarizes key parameters for the audio that resides on
the RF carrier of the FM signal, as illustrated below:
DEVIATION: The maximum frequency excursion from the carrier center
frequency is illustrated on this level bar. Typical maximum deviation, required by
Industry Canada or FCC, is 75 kHz to avoid bleeding into adjacent channel
bands of 200kHz bandwidths. 100% represents a full 75 kHz deviation.
RIGHT LEVEL: Right level bar represents the audio level on the right audio input
channel.
LEFT LEVEL: Left level bar represents the audio evel on the left audio input
channel.
DC VOLTAGE: The switching power supply DC output voltage is displayed here.
If additional screens, details, and settings are required, several additional
screens can be accessed through the SYSTEM SETTINGS button described
later in this section.
