FAQ
Q: To start a scan, I have to press the up or down button on the microphone for 7 seconds, any chance to shorten the pressing time?
A: The long press is not only related to scanning but also fast switch channels. 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.
