EB3A, is it possible to lock-out control panel for backpacking?.. every way i have tried, some button or control will get pushed, and then it will run down/discharge… i have tried finding a cover or something to cover it, and i have been able to make things work, but the covers will eventually dry out, crack, and fall apart… and it will be so much easier to just lock out the panel… also on the eb3a, is it allright to carry it on its back, that is, with the control screen facing up?.. if the eb3a can be transported with the screen facing up, that may eliminate having to lockout/cover the screen… … anyway, thanks in advance, i look forward to hearing from you, and have a great day/week/weekend… …
