Percent Key Operations
A total of five % functions are available. %1 and %2 are located on the default keyboard.
Your keyboard may be different.
Each function is individually programmable to add or subtract, from an individual item or
from a sale total, amounts ($ values) or percentages. You can also program the percentage
key taxable or non-taxable, so that sales taxes are calculated on the net, or the gross amount
of the item or sale. You can also program preset prices or percentages.
The operation examples in this section show the percentage key in a variety of
configurations. See "Function Key Programming" in the "Program Mode Programming"
chapter to assign a specific function to each percentage key.
Preset Percent Discount on an Item
In this example the%1 function is preset with a rate of 10 %.
1. Register the item.
2. Press the %1 key:
% 1
3. The discount is automatically subtracted.
