Question:

Can this microwave beep be shut off? It beeps continually unless connected to land power. It drives my wife crazy

My contact at Furrion advised that if your Furrion Built-In Microwave # FMSN09BL beeps continuously when it does not have a shore power connection it is most likely a warning indicator that the power source is not delivering sufficient operating voltage. This would explain why it does NOT have this issue when connected to more steady shore power. The operating manual, which I will email to you separately, notes that it is recommended to have a dedicated 20-amp circuit for this oven so that it does not have to share power with any other device.

You might try unplugging the microwave for a few minutes to allow its circuitry to fully power down, and then plug it back in. If there is another type of fault this may clear it.
