MX4200.2
13. Turn the scanner on.
14. Locate a small gray potentiometer on the printed
circuit board. The potentiometer looks something
like a gray plastic Phillips screw head. If the
scanner front panel is facing you, the pot will be
just behind the keyboard on the left side. (Don't
confuse this pot with the 3 pots along the right
edge of the board. The battery voltage sensor pot
is not near any other pot.)
15. Slowly adjust the potentiometer to the threshhold at
which the low battery indicator begins to flash.
This procedure worked with great success on an MX-4200,
and its battery life was increased from 2 to 7.5 hours.
I would like to thank Rick Meyer, WB9UFL, for finding the
potentiometer in his MX-4000, and Ron Smithberg for let-
ting me experiment with his MX-4200.
