Troubleshooting the Display

If the display does not turn on:

• Check the connection to the vehicle battery.

• The vehicle battery may be too low (below 1 volt) to power the ana-

lyzer. Fully charge the battery and retest.

• The analyzer’s 9-volt battery may need to be replaced. Follow the

directions in “Replacing the MDX P-300 Battery” and replace the

9-volt battery (alkaline recommended).

• If the analyzer does not power on when you press and hold the

MENU button, replace the 9-volt battery.

• If troubleshooting does not solve the problem, call 800-776-1995 to

obtain service. See “Patents, Limited Warranty, Service” on page 22

for more information.

Replacing the MDX P-300 Battery

The MDX-P300 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.
