No red dot visable romeo 5 - SIG SAUER Romeo5 1x20mm Compact Red Dot Sight Optimized for TREAD

If your having issues with the dot try this , make sure the battery is good ,if you can't see a dot hold the + button down for a full 30 seconds, if you still don't have a visible dot pump the + button untill you see one , I hope this helps , it worked for me ...
