Calibration
Why do we need to calibrate the True-D?
A Diversity receiver system is two receivers built into a single package, allowing the pilot to choose two
different antenna systems for maximum levels of video range & clarity. With two receivers used by
algorithm diversity, you need to get constant numbers between the two individual modules for calculation
of the best video signal in the goggles.
Note: when you update new firmware, you have to recalibrate your True-D.
How to do I calibrate the True-D diversity module?
Step 1: Plug True-D into the Fatshark goggles.
Note: Make sure all pins on True-D are correct when you plug in the Fatshark goggles.
Step 2: Plug Battery and make sure to turned on RX in the Fatshark goggles.
Step 3: Turn on your VTX.
Step 4: Press the Select button to open the navigation menu.
Step 5: Use Down button to scroll to the Setting menu.
Step 6: At the Setting menu, use the Down button to move the cursor to select the Calibrate function
and press the Select button. Then, wait for the process calibration completed and press Select button
to exit.
Calibrate: Utilize this menu to calibrate the True-D modules
for first time usage. It is highly recommended you
re-calibrate when using a different video transmitter.

Note: After Calibration, if you have a popup as below, please make as guide in this picture.
