| Post subject: | Uniwell UX-70 / CRC Error |
Dear colleagues, This is my first topic here. I am a owner of a electronic repair shop in Austria , and actually have a problem with a Uniwell UX-70 cash register. Regularly I don not repair cash ragisters, so I unfortunatelly do not have any experience in this field of electronic equipment. remedy: When you switch on the apparatus on the Disply one can read "CRC-Error" " E-99 " Maybe a colleague has had a similar problem, and can tell me the cause. Thanx in advance ...sorry for my bad english... |

I haven't had this error but if it is a file CRC problem, then it may be due to a flat or faulty battery. If the customer has switched the machine off for some time (such as a month or more), the battery will have gone flat and lost the programming. It would require a RAM clear and re-programming using the programming tables. They are in this manual: http://the-checkout-tech.com/manuals/ca ... anual.html |

Dear Admin, Many Thanx for your answer. Indeed the battery was faulty within this machine. I' ve allready replaced them, but the fault didn't changed. I will try to solve the problem by reprogramming it. I'll report the success. |

Ah, well, there you go. It must be RAM cleared if you change the battery since the memory will be corrupt. |

Dear Admin, Dear friends of cash registers So, in the mean time I could get a second cash register to copy the content of the RAM memory from one machine to the other via RS232 interface. But after inspection of the second machine I could detect a defective memory as well. So now I have two ragisters with the same fault. CRC ERROR 99 E - 99 I tried the RAM initial reset, but without success. Pls could you give me some advise about the steps to do. Many Thanx in advance Rados |

Look up RAM test. You must perform this procedure from the manual using the layout shown in the diagrams. |
