Batboard

I have two a5 spectras in a mobile install. One a dash mount uhf and the other a remote mount vhf. The backlight on the dash mount one always comes on with the setting set at what it was when it turned off. The remote mount always comes on with the backlight set to just the display and I have to manually change it. As far as I can see all the settings are the same. Can anyone provide some insight? Thanks

Have you swapped face plates between the units? They should be interchangable.

there is a setting in the RSS for default on power up

Ill double check that setting, and if that doesn't do it I'll swap heads. Thanks
