I use the battery on 4500 on aircraft startup, and the screen is very dark, and almost can't see it. How do I brighten up the screen when it is operating on battery only. After radio master on, screen is fine.

Please update to the latest software version 7.10.24. We now allow 100% DIM brightness on battery power. If you press the CHECK button, you can use the right knob to adjust the brightness to a more reasonable number like 80%.
