For obvious reasons this function would normally be set with a high
authority level.

The next function is error correct. This is used to cancel the last product
entered on the screen .It can not be used after subtotal or after a server
interrupt.

The no sale function is next this is mainly used to open the drawer
outside a transaction.

Function 15 and 16 are set as spare on the 850 and 880 models. Any
functions which are named spare are not used at present.
However on the UP5700 function 15 is the screen key. This is used to
change to another screen or keyboard.

Function 17 is named pre-set. However this function is no longer used
as there is a quicker method of assigning pre-set products to the
keyboard.

Function 18 to 33 are used for the payment types. You would therefore
allocate the function such as payment type 1 to the keyboard. Then
assign cash to be payment type 1, we covered the payment types in an
earlier section

Function 34 is auto receipt. This is the receipt on/off switch. The capital
letter A will be displayed to the server if the machine is in auto receipt
condition.

Function 35 is spare.

Function 36 is VIP. This function key is used to change the price band
of the products.
For example if product 10 is set to one pound for price band 1 and set
to zero for price band 4, you can set up the EPoS so that when the VIP
key is pressed, the products sold will be at price band 4.
The VIP price band key will be active for the transaction or until the VIP
key is pressed for a second time. Also the letter v will be displayed
informing the server that VIP key is active.
