The use of the VBar Control radio requires a VBar NEO or an RX
Satellite with a legacy VBar or Mini-VBar unit with firmware version 6.0
PRO or higher. This version is free for all legacy devices as an
incentive (but not for VBar NEO), for anyone who purchases a VBar
Control radio. After registering your VBar Control radio on www.vstabi.info, customers will be able to add and download firmware version 6.0 PRO free of charge, even for any VBars or MiniVBars they already own. More information on this process is available on www.vstabi.info.
