I have an HU2 with an Omnishot battery adapter. When I plug the Micro force V+F zoom control in and power up the hand unit, the low battery light just blinks really fast and is not operational. If I plug the zoom control in after powering up the HU2, it works just fine.
It’s definitely an omnishot adapter issue. When I use the stock Preston batteries everything works as it should.
Has anyone else experienced this issue? Is it ok to be plugging cables in while the unit is powered up like that?
