This document provides instructions for operating a point of sale system in training mode to allow cashiers to practice transactions without processing real payments. It outlines the following steps: 1) The cashier must sign into the system to activate training mode and a store-issued training card is required. 2) The system will switch to training mode and prompt for the training card and PIN to process a sample prescription without an actual sale. 3) Sample items can then be sold and the sale finalized to print a receipt, after which the training mode is ended by pressing the training mode button again.
