4.Use OSD to adjust VTX
which displays information like battery voltage and mAh consumed while you fly. In addition, the
Betaflight OSD can be used to configure the quadcopter, making in-field adjustments and tuning more
convenient.
MODE2 MODE1
The graphics above show the stick command to bring up the OSD menu. The stick command is: throttle
centered, yaw left, pitch forward. The exact stick command therefore depends on which mode your
transmitter sticks are in.
In the OSD menu, use pitch up/down to move the cursor
between menu items. When a menu option has a > symbol
to the right of it, this indicates that it contains a sub-menu.
Roll-right will enter the sub-menu. For example, in the
screen to the right, moving the cursor to “Features” and
then moving the roll stick to the right will enter the
“Features” sub-menu.
If you are using a video transmitter that supports remote
configuration, enter the “Features” menu to configure the
vTX. From there, enter either “VTX SA” if you are using
SmartAudio (TBS Unify) or “VTX TR” if you are using IRC
Tramp Telemetry.
To adjust PIDs, rates, and other tuning-related parameters,
enter the “Profile” sub-menu.
In the “Scr Layout” sub-menu, you can move the OSD
elements (like battery voltage, mAh, and so forth) around on
the screen.
The “Alarms” sub-menu lets you control when the OSD will
try to alert you that battery voltage is too low or mAh
consumed is too high.

When a parameter can be modified, the parameter’s current
value will be shown on the right-hand side of the screen. In
this case, roll left/right will adjust the parameter up and
down.
The screen to the right shows the current vTX settings. From
here, you can change the frequency band, channel, and
power level of the video transmitter. After making the
changes, move the cursor to “Set” and press roll-right to
confirm the settings.
