Re: power-up initialisation..?

2005-06-05 by srmaietta

Okay Colin,   I tried the func+page and nada.  but then when I cycled 
it off and on again, it came on as normal. (normal?)  I then cycled it 
again and did F1+7 and was able to clear data F1+F2.  Cycling further, 
with page this time to see if it would lock up again, and yes, holding 
Page upon power up loeft it blank, and now it exhibits the same 
behavior every time on power-up (a few leds lit or none, no PLED, and a 
quick flash upon power down.  

trying the FUNC+PAGE again in hopes of it working again. . nope. 
Perhaps it worked the first time because I hadnt messed with it for a 
few hours and some cap had discharged or something??  

thanks for following with me here..
