Fuel Range Indicator

[Jim Fraser <fraserj@fero.com>]

Hello, and happy muggy/rainy day to fellow N.E.ers!

I have a question about the fuel range (miles to empty) indicator in my
1990 CQ:
The unit becomes annoying because it counts down to *30,* then *E*
flashes in my face -- all when I have a good 75 miles or so left before
I come close to empty.  Now, I imagine this is some type of early
warning -- but it often flashes *E* when just under 1/4 tank remains,
even though I don't need to fill it for a few days.  I then either watch the 

light flash in my face with every startup, or switch to another display
every time.

Is there a way to adjust the fuel range indicator such that it not only
stops being so annoying, but could even become useful?  I've seen
mention of a pot on the back of the cluster for adjusting fuel range.
Should I give it a turn or two and see what happens?

Any info would be interesting...
