Method for setting an operational parameter in a medical device

A medical device, comprising:

• a display device,
• an input device which is actuatable to set an operational parameter displayed on the display device of the medical device, wherein the input device is advanceable in an actuation direction by movement steps to increase or decrease the operational parameter by a change amount associated with one of the movement steps and wherein the operational parameter is adjustable over a predefined overall numeric range with at least a first predefined numeric sub-range within the predefined overall numeric range and a second predefined numeric sub-range within the predefined overall numeric range,
• wherein each sub-range is associated with different predefined change amounts for a fine-tuning-state numeric value and a tuning-state numeric value by which the operational parameter is adjusted when in the respective state, and
• a control device for controlling operation of the medical device, the control device being configured to adapt, during advancement of the input device within a subrange, said change amount from the fine-tuning-state numeric value to the tuning-state numeric value larger than the fine-tuning-state numeric value in case a first condition is met,
• wherein the control device is configured to adapt said change amount in dependence of the advancement of the input device by being configured to apply a first set of values with the operational parameter in the first predefined numeric sub-range of the predefined overall numeric range and to apply a second set of values with the operational parameter in the second predefined numeric sub-range of the predefined overall numeric range.
