Critical Issue with HX v5.00 or later firmware

Applies To

  • Using the Customers Module in Uniwell Lynx with HX v5.00 or later firmware if your system has been setup to track customer balances at the POS Terminals by using a ‘Charge to customer’ media when finalising customer transactions

Issue Description

  • If a customer transaction is finalised using a ‘Charge to customer’ media and then a payment is made using the the Payment button on the Customer File screen the initial sales transaction is recorded in the EJF without the media and tax details and as such cannot be processed in Uniwell Lynx as a customer transaction


  • If the HX terminal has v5.00 or v5.10 series firmware then it must first be upgraded to v5.20 or later
  • Enable the ‘Calculate tax when charging to customer’ option (Program > Tax > Tax > System Option)
