  4. My terminal doesn’t read the barcodes, what can I do?
    If the terminal doesn’t read barcodes very well – or doesn’t read barcodes at all – please try to perform a cold boot. A red laser shield is placed on the front of the Memor. This shield has to be clean and without any scratches in order to perform the best scanning experience. Clean the laser shield using normal window-cleaning. If a scratch is too deep, the laser shield has to be replaced. In order to replace the laser shield, please return theDelfi Mira terminal to Delfi’s repair center using the RMA-form found on Delfi’s website;
