It is necessary to consider the customer's need to switch channels quickly. Therefore, when the button is pressed for less than 7 seconds, it quickly switches the channel. If it exceeds 7 seconds, the scanning function starts. Q: How to fast export and import to help manage 480 channels?A: Sorry, the QT40 framework do not support batch import and export function.
