So we just picked up this wonderful thing today! 😍 I'm just having issues setting it up and let's be honest, the manual is way too confusing! I tried to get them on the same channel and they both started beeping really loud! Does anyone know why that is or what I have to do to set it up properly? πŸ˜‚
