Our entry-level 21 connection unit comes pre-programmed with content of your choice, be it your business card, an animated file or simply a test promotion of your choice. Simply turn your unit on, and your message will begin broadcasting until it is switched off again. If you'd like to change the content of your content, just let us know - our creative team can design a new advert and ship it overnight on a USB memory stick, which means that all you have to do is turn on and plug in. The new content will automatically load your Solo unit and start broadcasting immediately. For more control, you can purchase the optional 'Blue-Caster' Windows-based interface. Once loaded to your laptop or PC, Blue-Caster enables the user to upload content to the unit using the supplied USB cable. You can then set specific broadcasting times, the duration of broadcasts, organise multiple content to run concurrently on the unit and retrieve statistics to monitor the success of your campaign.
