This article explains how to resolve lag or delayed response when using Remote Controller of the Deeper Quest or Spark.
Possible Cause
The most common cause of delayed or unresponsive manual control is that the controller requires calibration. Calibration resets the controller’s internal sensors and restores normal responsiveness.
How to Calibrate the Controller
Turn on the controller using the main power switch.
Press and hold both A and B buttons simultaneously for 3–4 seconds. The purple LED lights will flash briefly.
Release the buttons.
The flashing LEDs indicate that calibration is complete, and the controller is ready for use.
Additional tips:
