Using the numeric keypad
The numeric key pad enables you to enter quantities using a touch screen. You can also use it with a mouse pointer. It's just a bit more difficult to use than tabbing to, or clicking on, the quantity field and entering the quantities manually.
In auto mode the keypad enters numbers into the Item code field. To enter a quantity go to manual mode, scan the item then key in the quantity.
The keypad doesn't sum the values you enter. As in 1 + 2 = 3. It adds the number after the value already in the quantity field. As in 1 then 2 results in 12. If you want to add to, or subtract from, the quantity press the '+1" or "-1" keys. If you want to enter a quantity of 100, first press the "1", then "0" twice.
