discharge the bubbles. Press the spray button to spray the bubbles and press the button again
once all bubbles are discharged.
2. Flow Meter Calibration
1
In the app, tap Execute Operation to enter Operation View. Tap , then , and tap Calibration
on the right of the ow meter section.
2
Calibration starts automatically. After 25 seconds, the result of the calibration is displayed in the
app.
After calibrating successfully, users can proceed with the operation.
If calibration fails, tap “?” to view and resolve the problem. Afterward, recalibrate.
During calibration, tap , then to cancel. If the calibration is cancelled, the accuracy of the
ow meter is based on the data before the calibration was started.
When to Recalibrate
1. Installing a different nozzle model. Note: Choose the corresponding model in the app after replacing
nozzles. Go to Operation View, tap
, then for conguration.
2. Using a liquid of a different viscosity.
3. The error between the actual value and the theoretical value of the completed area is more than 15%.
Discharging the Bubbles in the Hoses
The T20 features an automatic bubbles discharge function. When it is necessary to discharge bubbles,
start the function through one of the two methods below. The aircraft will discharge automatically until
the bubbles are fully discharged.

Calibrating the Compass
It is important to calibrate the compass. The calibration result affects the ight safety. The
aircraft may malfunction if the compass is not calibrated.
DO NOT calibrate the compass where there is a chance of strong magnetic interference. This
includes areas where there are utility poles or walls with steel reinforcements.
DO NOT carry ferromagnetic materials with you during calibration such as keys or mobile phones.
If the aircraft status indicators show a blinking red light, compass calibration has failed. Please
recalibrate.
After calibrating successfully, the compass may be abnormal when you place the aircraft on
the ground. This may be because of underground magnetic interference underground. Move
the aircraft to another location and try again.
