Just bought a Variax Standard. Updated to latest firmware (was 2.21, now 2.23). Workbench HD loaded and working. All behaving as it should so far. The behavior of the battery status lights on the back of the guitar is a little odd, and not as described in the manual. Battery is fully charged. First press of the status button shows 4 lights, as it should. A second press lights up lights 1 to 4 in sequence (1 comes on, then goes off, then 2 does the same, then 3, then 4). A third press flashes light 2, then light 1, then light 1 a second time, then light 2 again. Fourth press goes back to showing the status (4 lights on again). Is this as it should be? What does it mean? It's not random - the sequence is exactly the same every time, so I'm guessing it's some sort of testing or status indication. I'm a bit worried about battery life though - I bought the guitar brand new today, but I know it's older stock and the serial number on the guitar starts Y15, which I guess means it's a 2015 guitar. Shelf life on these types of batteries is typically 3 years or so whether used or not.
