4.4 GLOBAL SYSTEM SETTINGS
Several Global settings and parameters should be reviewed and set after the unit is powered ON for the first time.
These settings are saved and do not need to be re-entered each time the unit is used.
To access the Settings Menu, press the Home/Settings button (Figure 4-1), then select Settings. This accesses
the Global Settings page (Figure 4-2).

4.4.1 Brightness
A slider bar (1) controls the screen brightness. To increase battery life, use as dim a setting as practical.
4.4.2 Ignore Alignment Prompt
The SDR-OMNI periodically (every 10 minutes, or if the internal temperature changes by 5⁰ F) runs an RF
alignment procedure to ensure maximum accuracy over temperature. This could possibly occur during an
extended avionics test (e.g., transmitting VOR/ILS/COMM/UAT or receiving ADS-B OUT data), thereby
interrupting the test. Checking this box (2) will suppress the alignment and ensure that the test is not interrupted.
If critical parametric testing is desired, this box should be unchecked so that the SDR-OMNI always operates at
the highest accuracy.
