I'm reaching out for some clarification on the device I'm just starting to use. Specifically, I'm curious about the slide button located beneath the flavor cartridge. I've seen other models with different configurations, and it's not entirely clear to me what purpose this button serves. Does it have a specific function that enhances the user experience or adjusts the device's settings in any way? I'm eager to understand how to make the most of my new device, and any insights you could provide would be greatly appreciated. Looking forward to your guidance on this feature, as I want to ensure I'm using it correctly and maximizing its potential. Thanks!
