The EBX-18 includes a “Battery Saver” jumper at location V13. This jumper keeps the Lithium
battery from discharging (keeping it disconnected) before the EBX-18 board is in the customer’s
hands and ready to be used. The default configuration of the jumper is a no-connect position
(placed only on pin 1). Figure 8 shows the location of the V13 Battery Saver Jumper.
