We do offer support to program departments on the Sharp ER-A320 cash register. Because the Sharp ER-A320 is no longer made and the manual is not available in PDF we no longer publish the directions.
If you need support programming the departments on you Sharp ER-A320 you will need your programming key. If you would like us to help over the phone we can do that for a fee. To arrange telephone support call us at 800-863-2274. Please do not call us looking for free support. We are happy to help you at our normal support rates.
