Got my CTX in the mail today. Assembled it without a hitch, but I can't get the battery to charge. The red lights to the far left will light for a moment then nothing. The remote LEDs do not light at all. Is the charging system faulty or did Minelab send me two fully charged units?( battery and remote). The manual mentions a switch; I sure as heck don't see any switch anywhere. Any words of wisdom?
