Note: When utilizing the SMART SEARCH
feature the True-D module will detect channels
that have the closest frequency with your VTX
transmission frequency and preference for
channels which you saved. Please ensure you
select your exact channel.
Band Scanner: Utilize to determine current
broadcast band, channels, and frequencies with
a powered video transmitter. Identify a
potential channel, band, and frequency with
low noise for optimal use. Quickly find a
pilot/VTX for spectating, troubleshooting, and
even locating your lost drone by observing
signal strength.

Settings: The setting menu is utilized to
configure the True-D module functions.
Alarm: Buzzer will warn you at configured low
signal level. The options are as follows: None,
25%, 35% and 50%. If a low signal is detected on
antenna A the buzzer will single beep and if a
low signal is detected on antenna B the buzzer
will dual beep.

options are as follows: None, 15 minutes, 30
minutes, 45 minutes.

Auto lock: To install ON/OFF in the setting
menu. If you choose “ON” mode, Screen will
auto lock after 10 seconds. If you choose “OFF”
mode, Screen will display continuously.
Units: show wave index in % or dBm.

Docking: To install ON/OFF in the setting menu.

Balanced mode, and the default recommend
stock setting. High: Slow switching speed, which
is optimal for long range.
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.
Calibration
Why do we need to calibrate the True-D?
A Diversity receiversystem 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, follow the instructions on the screen.

Step 7: Press the Select button to save & exit or exit. You will return to the Channel working space.
Note:
RSSI Value Standard when calibrating True-D:
-Min: 190 ± 30
-Max: 400 ± 40
If value RSSI is not in the range aboved, you should move your quad closer to the True-D .
