Software update
Key point: This menu is available only if a suitable USB memory unit, which is recognised by the receiver, has been connected. Otherwise you do not have access to this menu. This file with ‘.abs’ file extension can be downloaded from the website ‘www.edision.gr’ through a computer with internet
connection: http://www.edision.gr
Save the downloaded file to the USB memory unit and plug this unit into the USB port of ‘piccollino’.

In pratica devi scaricare da PC l'aggiornamento su una chiavetta USB e poi "passarlo" da questa al ricevitore.
