Constant beep alarm at key on

I had boat out yesterday fishing with no problems. Today, while in the garage, I turned the key on to check something on my Vessel View Mobile app, and the constant alarm tone is sounding. I can't get the code info from VVM, due to a problem accessing my account. I am working with Mercury to resolve that (which is what I was doing at the time I discovered the warning). Doesn't it sound odd to have a critical alarm sound before the engine even starts? From what I know, that alarm indicates failure into Guardian mode. It's been about 3 weeks since I got my boat back from replacing the shift actuator.

Is the kill switch on?

If the battery master supply switch is turned off, it will do this if you key on. I travel with mine off and havd stopped to get gas, turned on key to check gauge and that’s what happens

I just took it to shop to check the codes. None were found, and the beeping ceased after checking. Who knows about these things?

I just read this, and I think that is what i did. Forgot to turn on master battery switch. (I just went down and repeated it to test). Thanks to all who replied.

Don't feel bad, I have done the same thing several times. I always turn the battery switch off when my boat sits covered in the lift. Several times I turned the key on to start the fuel pump, and got the long beep and the word "fault" on my Smartcraft display. Turned the key off (realized what I had just done) and turned the battery switch back on and everything was fine.

+3 on the battery switch.
