MX4200.3
The low battery circuit on Ron's MX-4200 was misadjusted
to shut down the scanner prematurely when the battery
voltage fell below 4.7 volts. I readjusted the low bat-
tery threshhold to 4.0 volts.
You can use the same procedure, but you will need the
following equipment:
o An adjustable, regulated DC power supply, capable of
furnishing between 3 and 5 volts at 500 mA or more.
o An accurate means of measuring voltage from the
power supply. A digital voltmeter with an accuracy
of 5% or better is preferred.
o A #1 Phillips screwdriver.
o A Small, slotted screwdriver or alignment tool.
