Video Balance Adjustment
Range: 1=On, 2=Skip (exit)
The Video Balance Adjustment step is used to ensure that the wireless receivers’ video
levels are closely matched. This minimizes the brightness change that may occur when a
RX source is switched. Furthermore, skipping this adjustment can adversely affect video
performance so it is important to perform this step. It should also be repeated whenever
a new A/V receiver is installed or receiver positions are changed on the rear panel.
Note: The VID2 & VID3 balance adjustments are on the rear panel. A small
screwdriver is required to adjust them. DO NOT USE EXCESSIVE FORCE!
Note: The receiver video that is connected to RX1 is not adjustable and this source is
used as the video level reference when calibrating RX2 and RX3. Please see section
VIDEO RECEIVER BRIGHTNESS TEST
(page 4) before performing the Video Balance
Adjustment.
1.
With Diversity Demon installed, power up your FPV system. Point your video
camera at a background scene that offers good contrast and a noise free image
on the display.
2.
At the start of the balance adjustment mode the Green RX1 and RX2 LED’s will
rapidly toggle. This indicates that the RX1 and RX2 receiver sources are
constantly switching; What you see is the video from the two receivers in a ping-
pong fashion. The goal is to calibrate their brightness so that the two video
sources look the same (or nearly so).
While watching the video image, carefully adjust the VID2 trimmer pot to minimize
the brightness flicker between the two RX sources.
3.
Briefly press the pushbutton switch and confirm that the Green RX1 and RX3
LED’s are rapidly switching.
While watching the video image, carefully adjust the VID3 trimmer pot to minimize
the brightness flicker between the two RX sources.
4.
Briefly press the pushbutton switch to exit System Programming.
Note: If the battery voltage is too low the Video Balance feature will be disabled. Please
check for a low battery alert if you are unable to enable this fe ature.
