I guess I should ask what caller you are using and how old your TX 1000 is. I will say the TX1000 that came with my older Fusion isn’t near as bright as the one that came with my X2S. Foxpro says this had to do with the firmware update or something. I refuse to update the Fusion remote for the brightness issue but I think the update also increased the range of the remote.
Here’s a tip for your situation of switching from Day/Night mode without sticking your head inside your jacket or backpack… Assuming you don’t use the User button to control some other function you can set the “User” button to control the display mode settings. Game changer as I have been in the same situation on those bright snowy days where you haven't a clue where you are on the remote. Simply hit the user button to toggle between Daytime, Foxpro, Nighttime modes.
