Manual control refers to the act of operating or controlling a device, system, or process directly by human intervention, without the use of automated or remote control mechanisms. It involves physical interaction or manipulation of controls, switches, or interfaces to initiate, adjust, or stop the desired operation.

Manual control provides direct human input and allows for real-time adjustments or modifications according to specific needs or preferences. It can be advantageous in situations that require immediate response or fine-tuning, or when automation or remote control is not practical or necessary.
