I have an 898c. I hope I'm not imagining this, but the instant I push the power button, it appears that the screen changes from a very dim back light to black just prior to it starting the boot up process. It's like the screen has a constant very dim back light on even when the power is off. I'm not too concerned with that, but I sure don't want any power drain when the unit is not on. Anyone else notice this or am I just dreaming? Thanks anyone.
