[REULEAUX SAYS CHECK BATTERY WHEN FIRE BUTTON PRESSED]

I have Reuleaux DNA 200 and when the fire button is pressed it says CHECK BATTERY, and has Displayed WARRANTY SERVICE once and that went away. I have attached a screen shot of the device monitor screen. All three batteries currently in the device show 4.02 volts on a DVOM and were charged via LUC 4 bay charger.  Anyone have any ideas how to fix this? It was working fine last night.  

[Firing Button Issue]

It has worked flawlessly for the 2 months since i built it and just over the last few days has it been acting up. Maybe i will take it apart tonight and check it all out. 

[Firing Button Issue]

In my DNA mod the firing button does not always fire when pressed, it is also randomly locking without pressint the firing button 5 times in succession. Any insight as to why this may be occuring?
