I just finished installing my second ALP system.

It will not go into silent startup mode. I get about 28-30 beeps and a flashing red light before it goes into LDI mode. I've tried everything- updating the firmware, un-selecting the 3rd front sensor in park mode in the Config.

I have also tried to put it into silent startup mode manually.

Thought it may be a sensor issue, but I tested them and they are all working.

Any ideas?
