7.2Replacing the Battery

The lithium battery maintains power to the D400's built-in Real-Time Clock and NVRAM if there is a power disconnect. The D400 is supplied with a 1/2AA 3.6 V 0.9 Ah Lithium battery that you must insert on the D400 main board when the D400 is installed. To ensure the battery is good, it is recommended you replace the battery every five years.

You can access the battery compartment by removing the D400 main module from the chassis. The battery holder BT1 is located near the front corner of the board, behind the two rows of Serial Port Status LEDs.
