6. Charging the Internal Battery

The MS4000 has a built-in charger for its internal 12V, 4.5Ah sealed lead-acid battery. It is recommended to fully charge the unit before each use to ensure maximum memory retention capability.

1. Locate the charging port on the side of the MS4000 unit.
2. Connect the appropriate AC power cord (not included in all packages, check product contents) to the charging port and then to a standard wall outlet.
3. The Left LED indicator will illuminate RED, indicating that the unit is charging.
4. When the Left LED turns GREEN, the internal battery is fully charged.
5. Disconnect the unit from the power outlet once charging is complete.

7. Operating Instructions: Preserving Vehicle Memory

Follow these steps to use the MS4000 to maintain vehicle memory during a battery change:

1. Ensure the MS4000's internal battery is fully charged (Green LED on the charging indicator).
2. With the vehicle's ignition OFF and all accessories off, plug the MS4000's OBDII connector into the vehicle's OBDII port.
3. Once connected, the Green LED (Circuit Indicator) on the MS4000 should illuminate, indicating a successful connection to the vehicle's electrical circuit.
4. If the Amber LED (Low Battery Indicator) illuminates, the MS4000's internal battery voltage is 11.6 volts or lower, and it requires charging soon. It is recommended to charge the unit before proceeding with a battery change if the Amber LED is on.
5. With the Green LED illuminated, you can now safely disconnect and replace the vehicle's starter battery. The MS4000 will supply power to maintain the vehicle's memory.
6. After installing the new vehicle battery and reconnecting its terminals, remove the MS4000's OBDII connector from the vehicle's port.
7. Verify that all vehicle settings (radio presets, clock, etc.) have been retained.
