Do not remove the NGC board-mounted lithium battery or the
termination panel cable at this time. Removing the lithium
battery will cause a cold start and that may not be desirable.
When replacing the lithium battery, the termination panel
cable must remain connected to power the digital controller
assembly; otherwise, the unit will cold start. The user will
receive specific instructions during each procedure if either
cable should be unplugged.
As with all electronic components, caution should be used
when handling boards. Static electricity can potentially damage
board components, voiding any warranty.
