    Does anyone have a link to (or scan of) this manual? I found the VL-Plus manual on line, but there are a lot of differences between the 4030, 4030-VL1, 4030VL2 and Plus models.

    I suggest you contact Oleksandr at DREM. He's extremely responsive to issues with the DREM and rather tireless in pursuing solutions.
