+=============================+

Jumper J2 is used to configure the battery backup method.  To use the on-board battery, 
place a jumper block connecting pins 2-3.  If you wish to connect an external battery, 
pin 1 is the battery positive lead, and pin 4 is for battery negative.

You can clear the contents of the CMOS memory by placing a jumper block connecting 
pins 3-4, then turning on the power.  Turn off the power, configure the jumper for 
either the on-board or external battery, and turn the power back on.  The system
will act as if it has never been turned on before.
