Just picked up an Avengers machine by OK. Wondering if anyone who owns one also might have some insight into this one question...

On power up, I get a yellow screen that my translation app says contains the text "Power Supply. Please Wait." I'm thinking this is more likely to be "Power On, Please Wait". i.e. I'm booting. This is accompanied by an Alarm sound for about 10-15 seconds which goes off once the machine is up. It seems to play fine, for what I know about it so far, sound is good and all the gimmicks pass their self tests.

Is this a normal boot screen process for the machine, or is it indicative of a problem? I haven't reset it or anything as yet.
