Battery Backup Power Supply
9820K models can be equipped with an optional battery backup power supply. This allows the
last transaction data to be displayed for a minimum of 15 minutes. After the batteries reach a
certain low-voltage point, the power will automatically shut off. If you need to shut off the
battery power before the low-voltage point is reached, momentarily disconnect, then reconnect
the cable that plugs into P1 on the power supply.

Electronic Totalizer
The 9820K stores a running quantity total. This electronic totalizer works independent of the
optional mechanical totalizer that may be installed at the pump module, and is shown as whole
gallons (liters) on the displays (decimal point is shown, although it is disregarded). The
totalizer data is stored in battery-backed memory. The 9820K is supplied with an actuator
(
Figure 6-5 on page 47 ), which allows you to view and reset the electronic totalizer. When the
9820K is shipped, the actuator is attached with a tie wrap to the electronic chassis behind the
register door. At installation or startup, cut the tie wrap and remove the actuator. Retain for
future use.
