Saw a post "elsewhere" that the back light on the F75 is always on.

Doesn't seem a great idea for battery life. Now you can pulse the LED's at a rate that invokes optical continuity in the human brain, and this can save a fair amount of power. But now you're possibly creating a nasty noise source as the current is gated on and off at a particular rate.

zap the batteries pretty quick,maybe not,that would be a good question to ask Fisher for sure.

do you think they would release the machine if this was sucking down battery power? After all this time of getting it just right I think not.

Yes it's always on, but you don't even notice anything during the day, so it's not like a big bulb or something. Driven w. 4 AA batts it's still far better batt. life & lasts longer than say the typical 2 9-volts....
I still have all my bars after a week of lots of "playing"....that tells me batt drain is a non-issue.....
Seems to be alotta concern on this. I was wondering about it myself, but proof is in the pudding, my batts are lasting super long. Perhaps it even glows more at night? something else I can ask on...

to it in the background rather than light a bright light. Like I said, the batteries seem to last forever just like the T2, especially those of us accustomed to the 9 volt Fishers....
