in the domestic currency, then when the conversion key is pressed, the
exchange currency rate and amount due will appear. The amount is then
entered in the currency you have chosen. A new screen will then appear
and ask  which currency you want to give the change in.

Function 52 is the EAN key. This would be used to manually enter a bar
code, as opposed to scanning it.

Function 53 is price enquiry. If the server presses this key before
scanning or entering a bar code or product, the screen will display the
amount of the product, then you can continue to sell at this price, or
cancel.

Price override is similar to the previous key, except that the price of the
bar code or product will be displayed and the server will then be
prompted to sell at this price or enter another amount.
A practical example of this would be for end of date lines to be sold at a
reduced price.

The next key function is Item promotion.
As mentioned previously there are 9 promotions on the machines. The
item promotion will apply one of these promotions to an individual
product within a transaction.
The promotions can be set as  percentage discount, percentage
premium or mark-down amount.

Function 56 is promotion override. This will allow the server to carry out
the promotion when the promotion is not active.
For example if a promotion of 25% discount is set to be given each day
between 3 o’clock and 5 o’clock and this promotion is pressed at say
10 past 5, the screen will  warn the server that the promotion is not
active, they can then press the promotion override key to activate this
promotion.

Function 57 is subtotal promotion. This key would be pressed to give a
promotion for the subtotal.
The server would press the promotion number followed by the subtotal
promotion key.
