Removing the LCD Meter
Perform the following procedure to remove the LCD meter.

3. Loosen the two screws that anchor the LCD meter to the Electronics Module. These screws are captive and should
not be removed.
4. Firmly grasp the LCD meter and pull it straight away from the Electronics Module. Retain the six‐pin dual header for
later reinstallation.
