Working scope
The remote controller controls Qumi through infrared transmission, rather than direct control.
The working radius of the remote controller is about 7m (23 inches) and the working angle is
15° higher or lower than Qumi (However, the remote controller cannot be vertical to the side or
back of Qumi).
If Qumi fails to respond to the remote controller's commands, move the controller closer to
Qumi.
