The MDX-P00 uses a 9-volt battery (alkaline recommended) that allows
testing of 12-volt batteries discharged down to 1 volt in addition to sup-
plying power while the option menu is active. The MDX can test down to
5.5 volts when the internal 9-volt battery is not functioning. When the 9-volt
battery needs replacing, the tester displays LOW INTERNAL BATTERY,
REPLACE. Change the battery as soon as possible.
NOTE: The tester retains setup information while you change the 9-volt
battery.
1. Turn the tester face down.
2. Remove the screw securing the battery compartment cover using a
small Phillips screwdriver.
