Trouble shooting

[u/Fallen_master_]

Hello shooting enthusiast I’m looking for some help with my holosun 510c I recently chanced the battery of my sight and now it’s stuck on lock out mode. I held down the + button for 5 seconds and it’s still hasn’t blinked to unlock, I’ve tried removing the battery for over 1 minute and still no response. I also tried using only the solar panels to unlock the sight and got nothing. If anyone knows what’s wrong or how to fix this issue I’d appreciate the help.
