Almost certainly at least one of your Lighthouses is too close, in the wrong place, or having mechanical problems. Aside from placing them both at opposite corners of your ceiling, you could leave them running for a few days/weeks. They might wear themselves in.
If your problem cannot be resolved, maybe try using the headset with just one LH at a time, to find out which is more problematic, and RMA that unit.
In the past, I experienced this with my 5k+.
- LH 1.0 units were both mounted to the front wall.
Since then, a number of things done simultaneously resolved the problem.
- Moving both base stations to alternate ceiling corners, diagonal placement, instead of both on the front wall.
- Base stations as far and above the headset as possible.
- Replacement of 3 base stations so far just to get 4 working (RMA one LH 1.0 after a failure, RMA one LH 2.0 after immediate failure as published on these forums, replace one LH 2.0 after minor obstruction).
And now I do not experience such ‘grey outs’ even when deliberately trying to cover up the headset with both arms, whether using LH 1.0 or LH 2.0 .
