When an electrical device is labeled as "automatic," it signifies that the device is designed to function independently without the need for manual input. This means the device can initiate its operation, complete its tasks, and often shut itself off without requiring any direct action from a user. Automatic devices are built with sensors, timers, or programmable features that allow for this autonomous operation, making them efficient and user-friendly.

In contrast, other options suggest forms of operation that involve more direct human involvement. For example, a device that must be manually operated requires a person to turn it on or off. A device that needs a remote control still depends on the user to function, meaning it isn't fully automatic. Lastly, a device that operates only on a timer would still require presetting and thus introduces a level of manual input that "automatic" devices typically do not require. Overall, the essence of "automatic" is rooted in self-sufficiency in operation.
