BATTERY BACK-UP POWER SUPPLY
9820A models can be equipped with an optional battery back-up 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 re-connect, the cable
that plugs into P1 on the power supply.
VIEW/RESET TOTALIZER
Electronic Totalizer
The 9820A stores a running quantity total. This electronic totalizer works independent of the
optional mechanical totalizer that may be installed, 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 9820A is supplied with an actuator (shown in the above illustration)
which allows you to view and reset the electronic totalizer. When the 9820A 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 actuator. Retain for future use.
