When I turn on my Pro Plus 2 I get the diagnostic count down and then the unit flashes ALT 5 times and shuts down. The manual says the unit will perform an immediate shutdown if activated at elevations of 14,000 ft or higher. It doesn't have any further information. I'm in Santa Monica. I have no idea of my elevation. I can't find a thing about this online. Any Help?
