So my wife bought me a new sigelei ZMAX for X-mas. She gave it to me early on X-Mas Eve. I was using it all of X-mas eve and all day yesterday. Around 6 PM I started having issues. It iis telling me Low Load or Low Volume and powering itself off. When I get it to turn back on it will allow me one hit and then power off. The batteries are fully charged. Anyone have any ideas? Did I mess up a setting on this thing? Any help anyone can give me would be greatly appreciated.
