I just installed the Voice Pro 408 which has the SWV 2.021 version. I noticed a jack plug on the back on the unit that indicates external battery 6volt. Any idea how to get this.. or is plugging the unit into a Battery/Surge protector good enough?

The Voice Pro unit's do loose the programming upon a power outage. I suggest that the system be pluged into a UPS, we use a 500va UPS.
The battery back-up is only to keep your personal mailbox outgoing announcement and your voice messages that have been left in your Mailbox active upon a power outage.
