I recently purchased a 1022 with Livescope unit. I've used it two times and have had no issues with it. I was out yesterday and powered up the 1022 and Livescope and it came on for about 2 minutes then the screen went very dark. I powered it down and back up numerus times with the same results. When I tried to power up the 1022 only with a map displayed, it did the same thing. I was told that my voltage to the unit may have been too low. I got home and checked voltage on my battery and it was at 12.5 volts. I plugged the charger in for a while and tried to power up the 1022 and Livescope and it powered up properly. I just wanted to see if anyone has experienced the same thing with lower voltage.
