2.     Key mode must be turned to the OFF position
3.     Install the paper roll (making sure you hear a click when putting down the arm). You DO NOT have to put the plastic through the middle of the paper rolls, the spool is only used to gather the paper if you are keeping the journal.
4.     Plug in the machine and wait for the printer to print on the paper (if the machine shows E10 on the display, the paper hasn’t been inserted correctly) 
5.     Press 0 (forEnglish language) then CA/AMT TEND (the large cash button) 
6.     Enter the date in the format ddmmyy
7.     Enter the time using a 24hr clock

9.     Insert 2 x AA batteries (not supplied), if L appears on the screen the batteries have not been inserted correctly. 
10.   When entering a sum of money in to the till, DO NOT use a decimal point, £1.99 is entered as 199 then the department button. 

Receipt Printing Mode

How to set the machine to print standard customer receipts

PGM > 1 > CH 

How to set the machine to print journal mode

PGM > 0 > CH

The machine is printing a EURO symbol

The cash drawer doesn’t open more than a few inches

Inside the cash drawer is blue semi clear plastic clamp (which is used to hold down notes / receipts) which sometimes becomes lodged in the top of the cash drawer in transit – therefore stopping the drawer from opening correctly.

To resolve this – you can sometimes get a ruler in drawer and release it. Or failing that you will need to open the cash drawer as far as you can and pull on it until it releases it self.
