Battery Saver Jumper
The EPM-19 includes a “Battery Saver” jumper at location V4. This jumper keeps the Lithium
battery from discharging (keeping it disconnected) before the EPM-19 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 11 shows the location of the V4 Battery Saver Jumper.
