This RadShack Pro-2026 is the first scanner I've owned that has a constant 
backlit display.  I've heard and read that constant backlighting isn't 
necessarily a good thing because a) those things burn out sooner than later 
and b) they generate a bit of heat.  So I've got a few questions to ask of 
y'all:
1)   Can the tiny lightbulb be replaced with a clear/amber LED or perhaps a a 
group of them?
2)   If I install my own on/off switch, where would be a good place to mount 
it?  I'm hesitant to drill any more holes in the case - I figure they 
surrounded that thing with metal for a reason.
3)   Would a garden-variety photoresistor (coupled perhaps with a pot to 
adjust sensitivity) work as an automatic on/off switch, or would it be 
necessary to manufacture a switching circuit of some kind?  And, as with a 
switch, where would I mount the photoresister?
My current vehicle mounting scheme doesn't use the mounting knobs, so I guess 
I could use those holes, now that I think of it.
And, totally unrelated to the above...
4)   Anybody know how to disable the keypress beep on this thing?
