After controller battery was run down.
Charged for approx 25-28 minutes and unit would turn on with full screen detail. I tried to turn on immediately after battery was depleted with charge cable hooked to controller. Controller would not turn on. Checked again 10 minute point controller would not on. So waited for around 25-28 minutes and controller would come on. NOTE, I hooked coil to charger while waiting for controller battery to run down. After the around 25-28 minute mark detector controller come full on. I left charge cable hooked to controller with portable lithium battery. And battery icon in controller showed charging in progress. All systems go. Coil was still loaded in controller and it paired with no problem. Wireless hesdphones were still,loaded and reflected paired. I did unpair head phones and repaired them with no problem. After spending around 30 minutes with controller on trying to lock it up. I infact did. I never turned on backlight. I did turn external speaker control to max on controller. After screen locked up I still had detection. Meaning I had audio. No ID as screen was locked up. Showing 01 with pinpointer showing in the screen icon wise. I never had mi6 pointer with the unit. And never tried to pair mi6 pointer. Never! Meaning I didn’t have it out there hence never hit any button on any mi6 pinpointer.
So waiting for battery in controller to go dead again. And will do the same button sequence I think I did this last time the screen locked up. And will show this. Let’s see if screen locks up again stay tuned.
